Integrated LO Amplifi er: -4 dBm Input
Sub-Harmonically Pumped (x2) LO
High 2LO/RF Isolation: > 28 dB
LM3 SMT Package
General Description
The HMC265LM3 is a 20 - 31 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer downconverter with integrated LO and IF amplifi ers in
a SMT leadless chip carrier package. The 2LO to
RF and IF isolations are an excellent 35 to 48 dB,
eliminating the need for additional fi ltering. The
LO amplifi er 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
fi xture. Utilizing the HMC265LM3 eliminates the
need for wirebonding, thereby providing a consistent connection interface for the customer.
