Norm,
The LNB units are used on the C Band Satellite TV Receiving Dishes ( the
ones that are 8 to 15 ' in diameter). The DRO is a ceramic piece glued to
the PCB with a metal case around it and a adjustment screw. Some are fixed
in a metal can. The Mixer is used for 3.7 to 4.2 GHz Y may be able move
Hi all!
It sounds like two different schools of thought are at work here.
One is build it. Definitely cheep. Recreating a microwave receiver
with a final if that the Dongle can use shouldn't be a problem.
We need:
An antenna
Preamp/filter
Mixer
LO generator
Filter on the output of the mixer to the

Hi Norm, N3YFK
You need the book " The ARRL UHF/MICROWAVE
Experimenters Manual
ARRL Order No 3126 and ISBN 0-8
verter for 5760 MHz"
The article written by Rick Campbell, KK7B contains all
PCB plains and a list of material needed for it.
I hope this helps

Art,
How do I recognize the Dielectric Resonance Oscillator? Where might I
get one of these units? Where, how and with what do I plumb the rf
with?
Suggestion on parts re the lna ic and I assume a mixer ic?
Wonder about the limit of dead bug construction at GHz? What methods
might one use? I assum
Norm,
You could start with the 5.1 GHz DRO in an old C Band LNB for the LO. Add an
LNA IC, and Mixer. Use the IF section in the C Band LNB to cover cable loss.
