General Description
The HMC265LM3 is a 20 - 31 GHz surface mount sub-
harmonically pumped (x2) MMIC mixer downconverter
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 consistent
connection interface for the customer.
