General Description

The HMC258LM3 is a 14 - 20 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer with
an integrated LO amplifi er in a SMT leadless chip
carrier package. The 2LO to RF isolation is an
excellent 40 dB, eliminating the need for addi­tional fi ltering. The LO amplifi 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 fi xture. Utilizing the HMC258LM3
eliminates the need for wirebonding, thereby pro­viding a consistent connection interface for the
customer.
