24 GHz amplifiers

mm-Tech 1.5 watt linear amplifier:

A number of these amplifiers have made their way to the surplus market. They generally have an output of >1.5 watts (32 dBm) and some have been able to do 2 watts (33 dBm). Here are the specifications at 24.192 GHz:

WR-42 waveguide in and out
>55 dB small signal gain (these things are HOT!)
P1 dB approximately +30 dBm
Psat approximately+31.5 to +33 dBm with +32 dBm typical
-20 dBm input for full output typical
Noise Figure = 5-6 dB
VDC = + 12 VDC @ 1.25 amps
Size is 3.5" X 2" X 1"

A number of these amplifiers have also made their way to the surplus market. They generally have an output of .5 watts (27 dBm) at 24.192 GHz. Here some specifications for them:

A fairly large number of these amplifier have shown up over the last few years. They are very small units and some have waveguide inputs and outputs and others have female SMA connectors. Those that I have seen have not come with heatsinks so be careful with them. You MUST add a good heatsink to them because they will get very hot if you don't.
