HMC258LM3
GaAs MMIC SUB-HARMONIC
SMT MIXER, 14 - 20 GHz
v01.1201
General Description
Features
Functional Diagram
The HMC258LM3 is a 14 - 20 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer with an
integrated LO ampli er in a SMT leadless chip car-
rier package. The 2LO to RF isolation is an excellent
40 dB, eliminating the need for additional ltering.
The LO ampli er is a single bias (+5V) two stage
design with only 0 dBm drive requirement. All data is
with the non-hermetic, epoxy sealed LM3 packaged
device mounted in a 50 ohm test xture. Utilizing the
HMC258LM3 eliminates the need for wirebonding,
thereby providing a consistent connection interface
for the customer.
