http://www.peregrine-semi.com/content/products/broadband/broadband_mosfet.html But that's just a double-balanced mixer, of which there are many - some operating to about 40GHz or maybe more. A DBM isn't the same as an I/Q demodulator. In order to make an I/Q demodulator you would need 2 DBMs, a 2-way splitter, a 90 degree phase shifter, at least one variable-gain amplifier and maybe some other bits as well. The I/Q demodulators do all this on a single chip. regards Grant Yahoo!
