The HMC380QS16G is a high linearity down-converter receiver IC suitable for PCS/UMTS infrastructure applications from 1.7 - 2.2 GHz. The receiver IC is designed to support UMTS applications where a high third order intercept point is required. A passive mixer coupled with a high dynamic range IF amplifier achieves an input IP3 of +19 dBm. The converter provides a gain of 11 dB and 9 dB typical single side band noise figure. The IC operates from a positive +5V rail consuming 120 mA of current while only requiring a -5 dBm LO drive. The design requires no external baluns. The mixer supports IF frequencies between 50 MHz and 300 MHz.
