GENERAL DESCRIPTION

The ADRF5515A is an integrated, dual-channel, 3.3 GHz to 4.0

GHz, 20 W receiver front end ideally suited for time division duplex-

ing (TDD) wireless infrastructure applications. The ADRF5515A

consists of a high power switch and a two-stage low noise amplifier

(LNA) on each channel.

This user guide describes the ADRF5515A-EVALZ, designed to

easily evaluate the features and performance of the ADRF5515A. A

photograph of the ADRF5515A-EVALZ is shown in 

Figure 1

.

The ADRF5515A data sheet provides full specifications for the

ADRF5515A. Consult the ADRF5515A data sheet in conjunction

with this user guide when using the ADRF5515A-EVALZ.
