I've been trying a pair of these and have been happy with them so far:

E-PHEMT PreAmplifier

Note that it did take around a month for them to arrive since they're made to order, but I have yet to find anything else close to these specs for a reasonable price.
Very nice, how is it powered up ? I might get one ...what do they mean "Tuned Freq/?" like you enter a freq. in that range that you want it tuned to? I would be interested in the 150-174 one...N connectors...73,s Marcy

12 VDC power. And they factory tune it to your target frequency range - I had them tune mine for railroad frequencies (160 - 161 MHz).

With an IP3 of 40dBm the 1dB compression is probably in the 25dBm range and not bad. It would probably make a good preamp for a repeater as its narrow band at 3-4MHz wide at VHF and would be a little wider at UHF. But for general purpose scanner type use it needs to cover at least a complete band like 136-174 or 108-174 and you could run separate antennas for each band with its own preamp then combine with a triplexer, etc.

It probably uses a $3 PGA103+ pHEMT amplifier as the specs seems identical.

High IP3, +45 dBm Typ. at 2 GHz
Low Noise Figure, 0.6 at 1 GHz; 0.9 dB at 2 GHz
Gain, 11.0 dB Typ. at 2 GHz
P1dB +22.5 dBm Typ. at 2 GHz
May Be Used as a Replacement for RFMD SPF-5189ZA,B

I ordered from Stridsberg this past week. Rep on the phone was very friendly. He did say he/they were a little behind and it would be next week before my order shipped.
