Machining and Microwaves
In microwaves projects, especially above 10GHz, we oft need also a lot of mechanical components. Neil G4DBN presenting on his YouTube channel machining skills on lathe and milling machines. Neil G4DBN description of his YouTube channel: Machining and Ham Radio microwave and mm-wave radio experimentation. I make things, machine stuff on my Colchester lathe and Bridgeport mill, model things in…
Read More200 mW on 122/134 GHz by Michael DB6NT
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,…
