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 it up to 5.8 GHz. The LNA may be able to go there as well. The ARRL and THE RSGB have several books on making things in this band. A lot of surplus equipment at sites is being changed out for new, and you might find something that can be tuned down in frequency from the 6 GHz band. Mini-circuits has several Low Noise amplifiers and mixers that can be used. Suggest you check out their web site. Try to fine some Amateur Radio Microwave Activity in your area. Most of us will spend time helping others to "get on the air"
Good Luck, Art, KC6UQH http://www.minicircuits.com/homepage/homepage.html Good luck with the project -----Original Message----- From: Lizeth Norman [mailto:[email protected]] Sent: Sunday, November 11, 2012 10:04 PM To: [email protected] Cc: [email protected] Subject: Re: [amsat-bb] receiving 5.8 GHz
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 assume microstripline transmission lines.. No trips to AES, HRO or Skycraft here.. 73 de Norm n3ykf

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.

Hi all! What schemes are available for someone who only has a funcube dongle? It tops out at 1700 MHz. I am thinking hetrodyining using a brick and a double balanced mixer. Block down converter is another option. Any other options on the cheep side? Norm n3ykf _______________________________________________ Sent via [email protected].
