K-band source with dual-detectors and varactor modulator diode
click here for connection diagram and specification sheet
This unit has two detector diodes arranged so it can detect if something is moving toward or moving away from it. There is also a varactor modulator/AFC diode in this unit to set the transmit frequency or apply modulation, and it does have a 5 milliwatt Gunn diode and a standard WR-42(UG-595/U)flange output. Click here to see matching horn antenna! or you can make your own by downloading the N1BWT program available just below the photo. The units measure only .8"L x 1.03"W x .95"H, (20mm x 26mm x 24 mm) and are powered by 5 vdc. A mechanical adjustment screw easily adjusts the unit from about 22 to 25 ghz, and the varactor can electronicly control the frequency also. They are new, and the cost is $US75.00 each.

To download an Acrobat .pdf data sheet (140Kb), please click here 10 ghz source
This unit was made by M/A-Com, but is now made by MDT. They are exactly the same source. This device produces 10-15 milliwatts of RF output. It operates on +8 vdc, and includes a sensitive Schottky mixer/detector diode (200 ohms output impedance) for reception, and a varactor modulation diode that uses 1-20 vdc for up to 100 Mhz of frequency-control and modulation. A mechanical tuning-screw allows the frequency to be adjusted from about 9 ghz to about 11.5 ghz. Weight is about 5 oz, and measurements are 43 mm x 42 mm x 42 mm. Uses a standard UG-39 flange for RF connections.(here is the matching horn!) Ask for M/A-Com 10 ghz model when ordering. Each unit costs $US86.
Here are some links that describe possible data/wireless uses for these units:
