GENERAL DESCRIPTION

The ADRF5345 is a high linearity, single-pole, four-throw (SP4T)

switch manufactured in the silicon process.

This user guide describes the ADRF5345-EVALZ evaluation board,

designed to simply evaluate the features and performance of the

ADRF5345. A photograph of the evaluation board is shown in

Figure 1

.

The ADRF5345 data sheet provides full specifications for the

ADRF5345. Consult the ADRF5345 data sheet in conjunction with

this user guide when using the ADRF5345-EVALZ.
