just joined the forum, should have joined a long time ago !
I'm active on es'Hail and have built local 24cm and 9cm repeaters (GB3FT and FB) - but as you might expect es'Hail is more attractive for any number of reasons and quite a few of the locals are getting ready to operate thru' es'Hail so expect to see more activity from the NW of the UK.
Anyway I've pulled together all the key parts for a 13cm amplifier using a MRF24300N plus Rogers PCB material, FET, heat sink/spreader etc etc. Another local ham is going to CNC all the parts including the PCB pattern.
Hopefully it'll all work ok - if it does I have enough Rogers PCB material for about another 15 units.
The question is should I use the NXP broad band reference design or is there something more appropriate ?
Currently I'm leaning to copying the the design on page 6 of the NXP data sheet combined with a temp compensated bias circuit.
Luckily I have a well equipped workshop for test and alignment etc
