The AD9363 is a high performance, highly integrated RF agile transceiver designed for use in 3G and 4G femtocell applications. Its programmability and wideband capability make it ideal for a broad range of transceiver applications. The device combines an RF front end with a flexible mixed-signal baseband section and integrated frequency synthesizers, simplifying design-in by providing a configurable digital interface to a processor. The AD9363 operates in the 325 MHz to 3.8 GHz range, covering most licensed and unlicensed bands. Channel bandwidths from less than 200 kHz to 20 MHz are supported.
The two independent direct conversion receivers have state-of-the-art noise figure and linearity. Each Rx subsystem includes independent automatic gain control (AGC), dc offset correction, quadrature correction, and digital filtering, thereby eliminating the need for these functions in the digital baseband. The AD9363 also has flexible manual gain modes that can be externally controlled. Two high dynamic range ADCs per channel digitize the received I and Q signals and pass them through configurable decimation filters and 128-tap finite impulse response (FIR) filters to produce a 12-bit output signal at the appropriate sample rate.
The transmitters use a direct conversion architecture that achieves high modulation accuracy with ultralow noise. This transmitter design produces a best-in-class Tx EVM of −34 dB, allowing significant system margin for the external power amplifier (PA) selection. The on-board Tx power monitor can be used as a power detector, enabling highly accurate Tx power measurements.
The fully integrated phase-locked loops (PLLs) provide low power fractional N frequency synthesis for all receive and transmit channels. Channel isolation, demanded by FDD systems, is integrated into the design. All voltage controlled oscillators (VCOs) and loop filter components are integrated. The core of the AD9363 can be powered directly from a 1.3 V regulator. The IC is controlled via a standard 4-wire serial port and four real-time I/O control pins. Comprehensive power-down modes are included to minimize power consumption during normal use. The AD9363 is packaged in a 10 mm × 10 mm, 144-ball chip scale package ball grid array (CSP_BGA).

Markets and Technologies
The ADRV9363-W/PCBZ evaluation board will be available in June 2017. In the meantime you can use the AD-FMCOMMS3 for evaluation. The ADRV9363 will be in the same form factor and use the same FMC interface as AD-FMCOMMS3. It will be supported by the same carrier platforms and same software and tools. Limited by the functionality of AD9363, the ADRV9363 only supports 325MHz to 3.8GHz tuning range and up to 20MHz channel bandwidth. In addition, the ADRV9363 will use an on-board oscillator for external reference clock and it doesn’t offer EXT_LO test point.

The AD-FMCOMMS3-EBZ is a high-speed analog module designed to showcase the AD9361, a high performance, highly integrated RF transceiver intended for use in RF applications, such as 3G and 4G base station and test equipment applications, and software defined radios. Its programmability and wideband capability make it ideal for a broad range of transceiver applications. The device combines an RF front end with a flexible mixed-signal baseband section and integrated frequency synthesizers, simplifying design-in by providing a configurable digital interface to a processor or FPGA. The AD9361 chip operates in the 70 MHz to 6 GHz range, covering most licensed and unlicensed bands. The chip supports channel bandwidths from less than 200 kHz to 56 MHz by changing sample rate, digital filters, and decimation, which are all programmable within the AD9361 itself.
The AD-FMCOMMS3-EBZ provides software developers and system architect who want a single platform to operate over a wider tuning range than the AD-FMCOMMS2-EBZ. RF performance expectations of this board must be tempered with the very wide band front end. It does meet the datasheet specifications at 2.4 GHz, but does not over the entire RF tuning range that the board supports. Typical performance data for the entire range (70 MHz – 6 GHz) which is supported by the platform is published within the board documentation. This board is primarily intended for system investigation and bringing up various waveforms from a software team before custom hardware is complete. The objective being for designers to see waveforms, but not being concerned about the last 1dB or 1% EVM of performance. For performance-oriented platforms – please refer to the AD-FMCOMMS2-EBZ.
