Ka-LNA-2131-M

Multi-stage modular low noise amplifier.

Overview

The Ka-LNA-2131-M is a multi-stage modular low
noise amplifier that covers frequencies from 21
GHz to 31 GHz*. The LNA provides up to 34 dB gain
with a noise figure of 2.5 dB from a single supply
voltage from 7 V to 40 V. The LNA incorporates anenable/disable, current and temperature sensor
function allowing for remote fault analysis.
The LNA is fully enclosed in a housing with 2.92
RF connections and D-Sub for DC power, enable,
current and temperature sensor connection.
