Functional Diagram
General Description
The HMC264LM3 is a 20 - 30 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer with an
integrated LO amplifier in a SMT leadless chip car-
rier package. The 2LO to RF isolation is an excel-
lent 25 to 35 dB, eliminating the need for additional
filtering. The LO amplifier is a single bias (+3V to +4V)
two stage design with only -4 dBm drive requirement.
All data is with the non-hermetic, epoxy sealed LM3
packaged device mounted in a 50 ohm test fixture.
Utilizing the HMC264LM3 eliminates the need for
wirebonding, thereby providing a consistent connec-
tion interface for the customer.
