General Description

The HMC915LP4E is a high linearity, double-balanced converter that operates from 0.5 to 2.7 GHz and delivers a +28 dBm input IP3. The LO amplifier output and high dynamic range mixer input are positioned so that an external LO filter can be placed in series between them if necessary. The converter provides 28 dB of LO to RF isolation and is ideal for upconverter and downconverter applications. The IC operates from a single +5V supply consuming 88 mA and accepts LO drive levels of -2 to +4 dBm. The design requires no external baluns and supports IF frequencies between DC and 1 GHz. The HMC915LP4E is pin for pin compatible with the HMC552LP4E and the HMC215LP4E mixers with integrated LO amplifiers.
