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.
