Egtittite MICROWAVE CORPORATION HMC141C8 GaAs MMIC SMT DOUBLE-BALANCED MIXER6 -15 GHz FEBRUARY 1998 Features \ CONVERSION LOSS: 8.5 dB LO TO RF AND IF ISOLATION: > 30dB SURFACE MOUNT, NO THRU HOLES SMALL SIZE, NO DC BIAS REQUIRED * General Description The HMC141C8 is a miniature double-bal- anced mixer in a non-hermetic ceramic sur- face 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 consis- tency. This mixer has applications in point- to-point microwave radios and VSAT ground equipment where small size and surface mount compatibility are important.
