HMC265LM3
GaAs MMIC SUB-HARMONIC
SMT MIXER, 20 - 31 GHz
v01.1201
General Description
Features
Functional Diagram
The HMC265LM3 is a 20 - 31 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer down-
converter with integrated LO and IF ampli ers 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 ltering. The LO
ampli 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 xture. Utilizing the
HMC265LM3 eliminates the need for wirebonding,
thereby providing a consistent connection interface
for the customer.
Integrated LO Ampli er: -4 dBm Input
