GENERAL DESCRIPTION
The ADRF5048 is a SP4T, nonreflective switch manufactured in the
silicon process.
This user guide describes the ADRF5048-EVALZ evaluation board,
which was designed to simply evaluate the features and perform-
ance of the ADRF5048. A photograph of the evaluation board is
shown in
Figure
1.
Note that the ADRF5048 IC is populated on the ADRF5042 bare
evaluation board. However, the whole assembly is the ADRF5048-
EVALZ.
The ADRF5048 data sheet provides full specifications for the
ADRF5048. Consult the ADRF5048 data sheet in conjunction with
this user guide when using the ADRF5048-EVALZ.
