General Description
Electrical Specifications, T_A = +25° C
The HMC330 MMIC is a broadband double bal-
anced sub-harmonically pumped passive mixer that
may be used as an upconverter or downconverter.
The mixer requires no external matching or bias.This
design was optimized to provide better 1dB com-
pression performance as compared to the HMC266
under the same LO drive levels. The HMC330 pro-
vides greater than 38 dB LO to RF and 2LO to RF
isolation performance. Measurements were made
with the chip mounted and ribbon bonded into a
50-ohm microstrip test fixture that contains 5-mil
alumina substrates between the chip and K-connec-
tors. Measured data includes the parasitic effects
of the assembly. RF connections to the chip were
made with 0.076 mm (3-mil) ribbon bond with mini-
mal length <0.31mm (<12 mil).
