12GHz DIVIDE BY 8 PRESCALER

prescalerThis small board (which I found from this ebay source) uses the HMC363S8G by HITTITE,  a divide by 8 prescaler usable up to 14GHz. It is a very useful addition in my shack because now I can directly measure frequencies up to X band using my cheap Chinese frequency counter (it goes up to 2.7GHz, a video playing with it is here). The board is sandwiched between an aluminium and an ertalon plate. Input and output connectors are SMA. A small milled arrow denotes the proper signal direction.
