As an #RF designer, this rf amplifier seemed attractive to me, I bought it from #eBay and I think its design is beautiful. Anyway, I tested it and it gave almost 1 watt power in its output almost everywhere in the band.

PHA-202+ from @MiniCircuits test board. About +30dBm of P1dB. It seems to be a good component for pre-amplification, although if the second, third and fifth order harmonics were lower, it would add to its appeal.

@MakisSV1AFN I suggest that you use a helical structure (like temwell’s helical filters) to reduce the insertion loss, this amount of loss in the band will destroy the noise figure in the next stage.

@tomhajjar 1- Yes, it is true, it was interesting for me too. As it is known, the manufacturer claims that from 20 MHz to 1 GHz. I also tested it, with almost 0 dBm input, it gives about 30 dBm output power in the whole band.
