Manufactures high performance Silicon and Silicon Carbide semiconductors for Analog, Mixed Signal, Switching Power, RF Power & Microwave applications, Power Over.
Microwave Mods Microwave Modules (Liverpool, UK) made a range of RF products for the Amateur and professional markets. I've got some of their power amplifiers in various states of repair. Circuits (schematics) and manuals probably only exist on paper (if at all!) so I'll try and remember to add what I have to this page. You might also want to check out the which has some MM manuals. If you've sent me something in the past then thanks!

The stuff in no particular order.: MML 144-100LS 144MHz 100W out for 1 or 3W drive. Switched RX preamp. Thanks to Mike for the circuit.
I've got one of these and it works! MML 144-30LS 144MHz 30W out for 1 or 3W drive. Switched RX preamp. I bought one of these from an M1 station over the internet who assured me it was working. Caveat emptor. So I spent good money (38 Euros) on a MRF238 transistor and it now works.

You can get RF devices from for reasonable prices. Thanks Keith for the circuit.
MML 432-100 I don't have one of these but found the circuit whilst searching for information on a sick amplifier. The RF line-up of both amplifier is similar.
MML uses a single MRF646 driving a pair of devices. Earlier versions used the CM50-12A as the driver stage. It has a regulated bias circuit, VSWR protection and thermal shutdown - more protection for the devices than the 144MHz amplifiers!
BNOS uses a single MRF648 driving a pair of MRF648's. It also has a more sophisticated bias and control circuitry.
