HMC129G8
GaAs MMIC SMT DOUBLE-
BALANCED MIXER, 4 - 8 GHz
Features
Conversion Loss: 8 dB
LO to RF and IF Isolation: 30 dB
Small Size, No DC Bias Required
General Description
The HMC129G8 is a miniature double-balanced mixer
in a hermetic 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. Noise figure is essentially equal to the conver-
sion loss. The mixer can handle larger signal levels
than most active mixers due to the high third order
intercept. MMIC implementation provides excep-
tional balance in the circuit resulting in high LO/RF
and LO/IF isolations.
Electrical Specifications, T_A = +25° C, LO Drive = +15 dBm
