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.

I’m ready on 6cm with the same dish I’m using on 3cm.
Despite the strong local 5 GHz WiFi noise, had a nice 579/569 first QSO with this setup today with HB9Q, thank you Dan !
Setup is a 3.7m dish and 60W at CP feeder.
I can be QRV on 6cm or 3cm most of the days, skeds and tests are very welcome, as usual.
qrv 70cm, 33cm, 23cm, 13cm, 9cm, 6cm and 3cm.

I have a Rohde + Schwarz 90 deg angled adaptor male-male "RS LNW 2002/60"
sitting on my desk, mainly used as paperweight for some 20 years now. It is
marked "RS LNW 2002/60". I do not know the impedance but from the name I
presume it is 60 Ohms.
Can anyone confirm the 60 Ohms? Google did not help in this case.
If anybody wants to have it please mail me off-list @ BerndDF2ZC(a)gmail.com.
I can provide photo of course.
