I upgraded my DirecTV setup at home to a dual block converter. The
block converter is the little feed device that hangs out in front of the
dish and outputs a 1-2 GHz IF signal to the receiver in the house.
The old single block converter had done its job for several years and
was retired. I could not help opening it up to see what was inside.
It has a bunch of surface mount and strip line circuitry on a little
gold plated PC board. I recognize a voltage regulator, a quad op amp, a
555 timer, some chokes, a bandpass filter and some unrecognized strip
Does anyone have a block diagram or schematic diagram of this fine
example of microwave technology? Perhaps a magazine article was written.
I am just downright curious.
