DB6NT 122 134 GHzamateurradio hamradio power amplifier Endstufe

Most of the millimeter wave mixers used in the amateur radio sector are subharmonic mixers thatare also used for transmission. The transmission power generated in this way is usually around 0.2mW SSB or even less. Power amplifier chips for these frequencies are offered by Teledyne. Thesechips achieve a power of over 200 mW at 23 dB gain (TSC 115-145G-5S4C). However,…
