Description
The AMT2142021M is a connectorised LNA module operating in the 8.5 - 10.5 GHz
frequency range. The LNA exhibits 26.5 dB of nominal gain and has a typical mid-band
noise figure of 1.3 dB. The typical input return loss of the LNA is about 10 dB and the
output return loss 15 dB. The nominal 1 dB compression point is 14 dBm.
The LNA features field replaceable SMA connectors and can be used as a drop-in if
required. The module operates from a single +15 V supply.
