General Description
The HMC338LC3B is a 24 - 34 GHz Sub-harmonically
Pumped (x2) MMIC Mixer with an integrated LO
amplifier in a leadless RoHS compliant SMT package.
The 2LO to RF isolation is excellent at 30 dB,
eliminating the need for additional filtering. The LO
amplifier is a single bias (+3V to +4V) design with
a nominal -5 dBm drive requirement. The RF and
LO ports are DC blocked and matched to 50 Ohms
for ease of use while the IF covers DC to 3 GHz.
The HMC338LC3B eliminates the need for
wire bonding, allowing use of surface mount
manufacturing techniques.
