Microwaves the easy way?

http://www.chris-bartram.co.uk/
I've just discovered the GW4DGU website with details of (relatively) low cost assembled modules for 10GHz. The basic unit consists of a UDC10368C image-reject up/down converter (£149.90 built) which provides the basic up-down frequency translation needed to get a TX signal out on the band and a basic receive converter. Noise figure is not brilliant and TX power is low, but capable of being improved by additional preamps and PAs. Compared with a wideband FM system, even this used "stand alone" would be capable of decent results locally with a small satellite TV dish.

    That's a great link - thanks. No idea this stuff existed, but then I'm not a microwaver (well in spirit only).

    I didn't know either - this might be a fun way to get started!

    Yes, this approach, which could "grow" over time, would be a neat way of starting out on 10GHz. Start with the basic system PCB, then add RX preamp and a TX PA.

    I don't know about 10GHz, but off the top of my head I know of two other sources for Ham microwave stuff:
