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

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.
