General Description
The HMC128 is a miniature double-balanced mixer
chip that can be used as an upconverter or downcon-
verter. The device is a passive diode/balun type mixer
with high dynamic range. Noise figure is essentially
equal to the conversion loss. The mixer can handle
larger signal levels than active mixers due to the high
third order intercept. MMIC implementation provides
exceptional balance in the circuit resulting in high LO/
RF and LO/IF isolations. This mixer can operate over
a wide LO Drive input of +9 to +15 dBm.
