GENERAL DESCRIPTION
The HMC787A is a general-purpose, double balanced mixer in
a 12-terminal, RoHS compliant, ceramic leadless chip carrier
(LCC) package that can be used as an upconverter or down-
converter from 3 GHz to 10 GHz. This mixer is fabricated in a
gallium arsenide (GaAs), metal semiconductor field effect
transistor (MESFET) process and requires no external components
or matching circuitry. The HMC787A provides excellent local
oscillator (LO) to radio frequency (RF) and LO to intermediate
frequency (IF) isolation due to optimized balun structures and
operates with a LO drive level of 17 dBm. The ceramic LCC
package eliminates the need for wire bonding and is compatible
with high volume, surface-mount manufacturing techniques.
