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 amplifi 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 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 con-
sistent connection interface for the customer.
Integrated LO Amplifi er: -4 dBm Input

Typical Applications
The HMC265LM3 is ideal for:
20 and 31 GHz Microwave Radios
Downconverter for Point to Point Radios
LMDS and SATCOM
*Unless otherwise noted, all measurements performed as downconverter, IF= 2 GHz.
