HMC798LC4
GaAs MMIC SUB-HARMONIC
SMT MIXER, 24 - 34 GHz
v03.0110
General Description
Features
Functional Diagram
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.
