2300 MHz
• Medium Gain: 15.0 dB (Typ)
• Medium Output Power:
+12.0 dBm (Typ)

Description
The 2321 Series is a two-stage
thin-film bipolar RF amplifier
using resistive feedback and
active bias or temperature com-
pensation and increased Immunity
to bias voltage variations. Input/
output blocking capacitors couple
RF through the amplifier while a
low VSWR Is maintained through
inductive tuning. The 2321 Series
amplifiers are available in either
the TO-8 hermetic case or
connectored TC-1 package.

Connector Option
For TC-1 case the only connector option
available is the -1. The -1 option consists
of a SMA Female connector on both the
input and output (see note).
Model Number
Note: R-Series screening is not available in the TC-1 case as the case is non-hermetic.
