A very easy 35dB gain amplifier, 600-1700MHz ..
Using the two MMIC post mixer Ics contained within one of the now obsolete "bullet" LNBs.
Interestingly, doing this uses only about 5% of the cicuit board assembly! (so you are still left with 5 11GHz thingy-fets and an 11GHz diode mixer.
Power supply can be taken either as originally intended, down the coax (ie, no mods needed), or it can be tacked onto on of a couple of points. Isolating the DC from the output coax is easy enough if required.
Supply required: 12-18v at 80mA (as long as the internal 7805 that feeds the rest of the cct is removed)
The following pic shows the response up to 1300MHz. The lf response falls away mainly because of the high-pass filter incorporated between the last MMIC and the F connector.
