General Description
The HMC330 MMIC is a broadband double
balanced 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 compression performance
as compared to the HMC266 under the same
LO drive levels. The HMC330 provides 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-connectors.
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
minimal length <0.31mm (<12 mil).
