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 bal-
ance 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 sur-
face mount compatibility are important.
