10GHz Preamplifier
How do you build a 10GHz preamplifier from a Hirschmann LNB ??😋
.....and the measured data here:
Vy 73 de OE7DBH
Auxiliary equipment for various GHz measuring purposes and other test reports !
======= Broadband Low Noise Amplifier ======= Tested , Gain on 1264MHz : 38.25dB & -70dBm input 38.10dB & -100dBm input Usable operating frequency range: 600MHz.....3GHz ........and the next PCB is already installed in the housing ========= 10 GHz 3 stage preamplifier ======== 10 GHz preamplifier , .....used input section of old standard Kathrein LNB with waveguide input. 1. Oscillator switched off , 2. bandpass filter disconnected , 3. coupling capacitor and output added ( everything else remains original ! ) Gain ( i expect around 30dB ) and noise figure will be measured soon. Here's a...
