QRP 5W HF linear amp transistors and design
Dear all
I want to build a power amp for SSB HF 1.5-30 MHz Specs approx 5W out Cheap/easy to source components Surface Mount parts/small Rugged/stable into any/most loads Gain around 40 dB Flat gain to 1 dB or so Thought I would do something like Class A MMBT2222 - 2X push pull MMBT2222 - finals push pull balanced What to do for the finals? I looked at the PD55003 RF MOSFETS - can you get these easily? Will they work down to HF? What other issues? What about transformers? Is this a practical proposition? I havent seen any similar designs I would be grateful for some pointers Thanks Richard |
