The transition of test and measurement capabilities from 4G to 5G is not a simple step up. It is an evolutionary leap beyond the performance of current equipment in the development and operation ecosystem. A wider frequency spectrum. Unsurpassed millimeter wave bandwidths (28 GHz and 39 GHz). And standards that are forming but are still incomplete. These are just some of the challenges. And before they can be met, they have to be measured and tested.

We can help you do that with the broadest RF portfolio, the highest-performing converters, and deep expertise all along the signal chain.

CN0511

DC to 5.5 GHz Signal Generator with +/-0.5 dB Calibrated Output Power X +

CN0511

A high frequency, low distortion, low noise signal source is a necessity when testing and debugging communication, radar, and other RF systems. Synthesized RF signal generators are standard equipment in RF test labs, but often require additional filtering when low distortion or low broadband noise is required.

The system shown in Figure 1 is a complete DC to 5.5 GHz sine wave signal generator based on a direct digital synthesis (DDS) architecture. A quad-switch digital-to-analog converter (DAC) core and integrated output amplifier provide exceptionally low-distortion over the entire operating frequency range, with a matched 50 Ω output termination.

A wide bandwidth amplitude calibration ensures that the output power, from 0 dBm to -40 dBm, stays within +/-0.5 dB over the entire operating frequency range.

The onboard clocking solution includes a reference oscillator and phase-locked loop (PLL), eliminating the need for an external clock source. All power is derived from a Raspberry Pi platform board, with ultra high power supply rejection ratio (PSRR) regulators and passive filtering to minimize the impact of the power converters on RF performance.

With this highly integrated solution, wide bandwidth and accurate output power performance comparable to that of commercial benchtop signal generators is now available in a small, low cost, open source reference design.

CN0366

A 40 GHz Microwave Power Meter with a Range from −30 dBm to +15 dBm X +

CN0366

The circuit shown in Figure 1 is an accurate 40 GHz, microwave power meter with a 45 dB range that requires only two components. The RF detector has an innovative detector cell using Schottky diodes followed by an analog linearization circuit. A low power, 12-bit, 1 MSPS analog-to-digital converter (ADC) provides a digital output on a serial peripheral interface (SPI) port.

A simple calibration routine is run before measurement operation, at the particular RF frequency of interest. The user can then operate the system in measurement mode. When in measurement mode, the CN-0366 Evaluation Software displays the calibrated RF input power that is applied at the input of the detector in units of dBm.

The total power dissipation of this circuit is less than 9 mW on a single 5 V supply.

CN0302

Ultra-Fast Settling PLL with RF to 13 GHz X +

CN0302

The PLL circuit shown in Figure 1 uses a 13 GHz Fractional-N synthesizer, wideband active loop filter and VCO, and has a phase settling time of less than 5 μs to within 5° for a 200 MHz frequency jump.

The performance is achieved using an active loop filter with 2.4 MHz bandwidth. This wide bandwidth loop filter is achievable because of the ADF4159 phase-frequency detector (PFD) maximum frequency of 110 MHz; and the AD8065 op amp high gain-bandwidth product of 145 MHz.

The AD8065 op amp used in the active filter can operate on a 24 V supply voltage that allows control of most wideband VCOs having tuning voltages from 0 V to 18 V.

Low Noise, 12 GHz, Microwave Fractional-N Phase-Locked Loop (PLL) Using an Active Loop Filter and RF Prescaler X +

CN0174

This circuit is a complete implementation of a low noise microwave fractional-N PLL using the ADF4156 as the core fractional-N PLL device. The ADF5001 external prescaler is used to extend the frequency range of the PLL up to 18 GHz. An ultralow noise OP184 op amp with appropriate biasing and filtering is used to drive a microwave VCO to implement a complete low noise PLL at 12 GHz with a measured integrated phase noise of 0.35 ps rms. This function is typically used to generate the local oscillator frequency (LO) for applications such as microwave point-to-point systems, test and measurement equipment, automotive radar, and military applications.

CN0369

Translation Phase Locked Loop Synthesizer with Low Phase Noise X +

CN0369

The circuit block diagram shown in Figure 1 is a low phase noise translation loop synthesizer (also known as an offset loop). This circuit translates the lower 100 MHz reference frequency of the ADF4002 phase locked loop (PLL) up to a higher frequency range of 5.0 GHz to 5.4 GHz, as determined by the frequency of the local oscillator (LO).

Figure 1. Block Diagram of the Translation Loop Synthesizer

The translation loop synthesizer has very low phase noise (<50 fs) in contrast to a synthesizer using only a PLL. The low phase noise is because of the very low N value used by the ADF4002 integer-N PLL, which controls the voltage controlled oscillator (VCO). In this example, the ADF4002 phase frequency detector (PFD) runs at 100 MHz, and N = 1, yielding phase noise performance that is not limited by the N value of the PLL.

AD-FMCOMMS5-EBZ

Dual AD9361 Evaluation Board

4 Tx, 4 Rx 70 MHz - 6 GHz X +

AD-FMCOMMS5-EBZ

The AD-FMCOMMS5-EBZ is a high-speed analog module designed to showcase the AD9361 in multiple-input, multiple-output (MIMO) applications. The AD9361 is a high performance, highly integrated RF transceiver that operates from 70 MHz to 6 GHz, and supports bandwidths from less than 200 kHz to 56 MHz. The AD-FMCOMMS5-EBZ supports dual AD9361 devices, allowing for the creation of a 4x4 MIMO system. This platform is intended to enable the prototyping and development of many software defined radio applications, such as active antennas, transmit beamforming, and receive angle of arrival systems. The AD-FMCOMMS5-EBZ board has both wideband channels covering the full 6 GHz range, as well as narrowband channels matched to 2.4GHz. The AD-FMCOMMS5-EBZ also contains dual ADG918 SPDT switches, which create a calibration matrix between the two AD9361s. This switch matrix hardware, combined with the Analog Devices supplied API software, allow for a full digital and RF synchronization between the two AD9361s. The providing APIs also support full independent device configuration of the two AD9361s.

Because the AD-FMCOMMS5-EBZ supports both narrow and wideband input and output connectivity, it provides RF engineers the ability to connect the AD9361 to a RF test bench (vector signal analyzer, signal generator, etc.) and measure narrowband performance, as well as providing software and system engineers the ability to quickly prototype across the full 6 GHz operating range. Additionally the AD-FMCOMMS5-EBZ allows for both AD9361 devices to receive an on-board generated external LO signal, which can provide improved RF performance.

AD-FMCOMMS6-EBZ

AD-FMCOMMS6-EBZ Evaluation Board

X +

AD-FMCOMMS6-EBZ

The AD-FMCOMMS6-EBZ eval board is a 400MHz to 4.4GHz receiver based on the AD9652 dual 16bit analog to digital converter, the ADL5566 High Dynamic Range RF/IF Dual Differential Amplifier and the ADL5380 quadrature demodulator.

This is an I and Q demodulation approach to direct convert (also known as a homodyne or zero IF) receiver architecture. Direct conversion radios perform just one frequency translation compared to a super-heterodyne receiver that can perform several frequency translations. One frequency translation is advantageous because it:

Reduces receiver complexity and the number of stages needed, increasing performance and reducing power consumption
Avoids image rejection issues and unwanted mixing

This topology will provide image rejection and early implementation of the differential signal environment. There is an amplification stage to maintain the full-scale input to the ACD. The local oscillator and ADC clock are on board and share the same reference signal prevent smearing. The form factor is VITA57 compliant and all of the DC power is routed from the data capture board through an FMC connector. This evaluation board demonstrates a high performance receiver signal chain aimed at military and commercial radar using “commercial off the shelf” (COTS) components. The overall circuit has a bandwidth of 220MHz with a pass band flatness of +/_ 1.0 dB. The SNR and SFDR measured at an IF of 145MHz are 64dB and 75dBc, respectively.
