GENERAL DESCRIPTION
The HMC798ALC4 is a 24 GHz to 34 GHz subharmonically
pumped (×2) MMIC mixer with an integrated LO amplifier housed
in a leadless, RoHS compliant LCC package. The HMC798ALC4
can be used as an upconverter or downconverter between 24 GHz
and 34 GHz.
The 2 × LO to radio frequency (RF) isolation is typically 30 dB
in a 24 GHz to 30 GHz frequency range and 36 dB in a 30 GHz
24 GHz to 34 GHz, GaAs, MMIC,

to 34 GHz frequency range, eliminating the need for additional
filtering. The LO amplifier is single bias at a 5 V dc with a
typical 4 dBm LO drive level requirement The HMC798ALC4
eliminates the need for wire bonding, allowing use of surface-
mount technology (SMT) manufacturing techniques.
