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.

The circuit board used in the fi nal application should
use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown. A
suffi cient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon
request.
