Description
The HMMC-3122 is a packaged
GaAs HBT MMIC prescaler
which offers DC to 12 GHz frequency translation for use in
communications and EW systems incorporating high-frequency PLL oscillator circuits and
signal-path down conversion applications. The prescaler provides a large input power
sensitivity window and low
phase noise.

Operation
The device can be operated from

either a single positive or single
