I am offering a wideband preamp based on this device. It is a 2 stage
preamp to increase gain to 38 dB.
Performance is really good across multiple bands.

Do you still build preamps? Thanks!

*Subject:* [Moon-net GG] new experiment ...
I have been playing with a new Triquint ULNA device (TQP3M9036). It
Shows a lot of promise. It is like a MAR or MSA device in that it is
50ohm in and out. and has a claimed NF about .4db nf ( their numbers).
I have built several pramps to test them and have gotten even better
than they claim and they cover 50-1296 with ease and NF is .4ish or
below. The S11 and S22 are both great and the OIP3 is +35db also
...very nice device. It has great promise as a good terrestrial LNA.
Preamps are foolproof to build and would cost under $50 if all the best
quality parts are used.
