LM3 SMT Package
General Description
The HMC265LM3 is a 20 - 31 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer down-
converter with integrated LO and IF amplifiers in
a SMT leadless chip carrier package. The 2LO to
RF and IF isolations are an excellent 28 to 47 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 HMC265LM3 eliminates the
need for wirebonding, thereby providing a con-
sistent connection interface for the customer.
