HMC142C8
GaAs MMIC SMT DOUBLE-
BALANCED MIXER, 6 - 15 GHz
Features
Input IP3: 20 dBm
Conversion Loss: 8.5 dB
LO to RF Isolation: 35 dB
General Description
The HMC142C8 is a miniature double-balanced
mixer in a non-hermetic ceramic surface mount
package that can be used as an upconverter or
downconverter. The device is a passive diode/
balun type mixer with high dynamic range. The
mixer can handle larger signal levels than most
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 and unit-to-unit consistency. This
mixer has applications where small size and surface mount compatibility are important.
