The ADF4371 allows implementation of fractional-N or Integer N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. The wideband microwave voltage controlled oscillator (VCO) design allows frequencies from 62.5 MHz to 32 GHz to be generated.
The ADF4371 has an integrated VCO with a fundamental output frequency ranging from 4000 MHz to 8000 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allows the user to generate radio frequency (RF) output frequencies as low as 62.5 MHz at RF8x. A frequency multiplier at RF16x generates from 8 GHz to 16 GHz. A frequency quadrupler generates frequencies from 16 GHz to 32 GHz at RF32x. RFAUX8x duplicates the frequency range of RF8x or permits direct access to the VCO output. To suppress the unwanted products of frequency multiplication, a harmonic filter exists between the multipliers and the output stages of RF16x and RF32x.
Control of all on-chip registers is through a 3-wire interface. The ADF4371 operates with analog and digital power supplies ranging from 3.15 V to 3.45 V, and 5 V for the VCO power supply. The ADF4371 also contains hardware and software power-down modes.

Evaluation Kits (2)
The EV-ADF4371SD2Z evaluates the performance of the ADF4371 frequency synthesizer with an integrated voltage controlled oscillator (VCO) for phase-locked loops (PLLs). The evaluation board contains the ADF4371 frequency synthesizer with an integrated VCO, a USB interface, power supply connectors, and subminiature Version A (SMA) connectors.
This board requires an SDP-S board (not supplied with the kit). The SDP-S allows software programming of the EVADF4371SD2Z device.
Full specifications for the ADF4371 frequency synthesizer are available in the product data sheet, which must be consulted in conjunction with this user guide when working with the evaluation board.
The Quad-MxFE System Development Platform contains four MxFE® software defined, direct RF sampling transceivers, as well as associated RF front-ends, clocking, and power circuitry. The target application is phased array radars, electronic warfare, and ground-based SATCOM, specifically a 16 transmit/16 receive channel direct sampling phased array at L/S/C band (0.1 GHz to ~5GHz). The Rx & Tx RF front-end has drop-in configurations that allow for customized frequency ranges, depending on the user’s application.
The Quad-MxFE System Development Platform highlights a complete system solution. It is intended as a testbed for demonstrating multi-chip synchronization as well as the implementation of system level calibrations, beamforming algorithms, and other signal processing algorithms. The system is designed to mate with a VCU118 Evaluation Board from Xilinx®, which features the Virtex® UltraScale+™ XCVU9P FPGA, with provided reference software, HDL code, and MATLAB system-level interfacing.
In addition to the Quad-MxFE Digitizing Card, the kit also contains a 16Tx / 16Rx Calibration Board that is used to develop system-level calibration algorithms, or otherwise more easily demonstrate power-up phase determinism in situations pertinent to their own use case. The Calibration Board also allows the user to demonstrate combined-channel dynamic range, spurious, and phase noise improvements and can also be controlled via a free MATLAB add-on when connected to the PMOD interface of the VCU118.
The system can be used to enable quick time-to-market development programs for applications like:
- ADEF (Phased-Array, RADAR, EW, SATCOM)
- Communications Infrastructure (Multiband 5G and mmWave 5G)
- Electronic Test and Measurement
