DESCRIPTION
The STM351-2 module is designed to be used
as a linear RF Power Amplifier for WLL or other
fixed radio a ccess subscriber applications.
This particular model is one of several in de-
sign covering the 300-5 00 MHz freque ncy
range in individual bandwidths of 25 MHz
each.
Band splits and corresponding part numbers
for all bands are as follows:
