General Description

The HMC128 is a miniature double-balanced mixer chip that can be used as an upconverter or downconverter. The device is a passive diode/balun type mixer with high dynamic range. Noise fi gure 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.

Features

Conversion Loss: 7 dB
