Abstract
A microwave mixer is integrated with an yttrium-iron-garnet (YIG) tuning element to provide a YIG tuned heterodyne conveter or mixer. An input signal is provided to the YIG tuning element by an input coupling loop and local oscillator power is provided to an output coupling loop. A mixing diode is connected in series with the output coupling loop close to the YIG tuning element, and the mixing products appear on the output coupling loop. The output coupling loop is connected to a circuit which separates the local oscillator input signal from the intermediate frequency output signal.
