AD9361

 

The AD9361 is a high performance, highly integrated radio frequency (RF) Agile Transceiver™ designed for use in 3G and 4G base station applications. It is developed and manufactured by Analog Devices company.

Its programmability and wideband capability make it ideal for a broad range of transceiver applications. The device combines a 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 AD9361 receiver LO operates from 70 MHz to 6.0 GHz and the transmitter LO operates from 47 MHz to 6.0 GHz range, covering most licensed and unlicensed bands. Channel bandwidths from less than 200 kHz to 56 MHz are supported.

The two independent direct conversion receivers have state-of-the-art noise figure and linearity. Each receive (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 AD9361 also has flexible manual gain modes that can be externally controlled. Two high dynamic range analog-to-digital converters (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 error vector magnitude (EVM) of <−40 dB, allowing significant system margin for the external power amplifier (PA) selection. The on-board transmit (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 frequency division duplex (FDD) systems, is integrated into the design. All VCO and loop filter components are integrated. The core of the AD9361 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 input/output control pins. Comprehensive power-down modes are included to minimize power consumption during normal use. The AD9361 is packaged in a 10 mm × 10 mm, 144-ball chip scale package ball grid array (CSP_BGA).

5. User Guide : (FII-BD9361 can use it )

https://wiki.analog.com/resources/eval/user-guides/ad-fmcomms3-ebz

FII-BD9361 is developed by Fraser Innovation INC. It is absolutely compatible with AD-FMComms3-EBZ Board. The purpose of the AD-FMComms3-EBZ is to provide an RF platform to software developers, system architects, etc, who want a single platform which operates over a much wider tuning range (70 MHz – 6 GHz). It’s expected that the RF performance of this platform can meet the datasheet specifications at 2.4 GHz, but not at the entire RF tuning range that the board supports (but it will work much better than the AD-FMCOMMS2-EBZ over the complete RF frequency). We will provide typical performance data for the entire range (70 MHz – 6 GHz) which is supported by the platform.

This is primarily for system investigation and bring up of various waveforms from a software team before their custom hardware is complete, where they want to see waveforms, but are not concerned about the last 1dB or 1% EVM of performance.

You can find the user guide in above link at analog website. We will send you hardware configuration and system Scheme Diagram when you purchase this products.
