General Description
The HMC218BMS8GE is an ultra miniature dou-
ble-balanced mixers in an 8 lead plastic surface
mount packages (MSOP). This passive MMIC mixer
is constructed of GaAs Schottky diodes and novel
planar transformer baluns on the chip. The device can
be used as an up-converter, down-converter, bi-phase
modulator / demodulator, or phase comparator. This
mixer performs well when used as a down-converter
from 3.5 to 8 GHz and as an up-converter from 4.5 to 8
GHz. The low conversion loss, high isolation and wide
IF bandwidth make this mixer ideal for a variety of Rx
and Tx frequency plans.
