ADRF5519-EVALZ User Guide
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
The ADRF5519 data sheet provides full specifications for the
ADRF5519. Consult the ADRF5519 data sheet in conjunction with
this user guide when using the ADRF5519-EVALZ.
