General Description
The HMC798LC4 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 +5V design with a
nominal +4 dBm drive requirement. The RF and
LO ports are matched to 50 Ohms for ease of
use while the IF covers DC to 4 GHz. The HMC798LC4
eliminates the need for wire bonding, allowing use of
surface mount manufacturing techniques.
