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.
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.
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
