Motorola Part Number 52-P01413/C, Frequency Sources Part Number DRO-53-03. +5VDC. Stated range 5.4 to 5.9 GHz. SMA output connector. We don't know the exact specs such as output level, etc but we did a quick non-specific check and found the freq will range from about 5.3xx GHz to just a bit over 6 GHz. As to output level I am physically padded down 36dB between the device and my instruments but I do not have any reference specs. Measures about 1-5/8" x 1-3/8" on the mounting base. Looks like it would make a nice 5 GHz ham gadget. Since we cannot account for the end user expertise, it is sold as-is as-found with no return or warranty.
