GENERAL DESCRIPTION

The ADRF5519 is an integrated, dual-channel, 2.3 GHz to 2.8 GHz,

20 W receiver front end ideally suited for time division duplexing

(TDD) wireless infrastructure applications. The ADRF5519 consists

of a high power switch and a two-stage low noise amplifier (LNA)

on each channel.

This user guide describes the ADRF5519-EVALZ, designed to

easily evaluate the features and performance of the ADRF5519. A

photograph of the ADRF5519-EVALZ is shown in
