HMC421QS16 / 421QS16E v04.0810 MIXERS - DOWNCONVERTERS - SMT 9 PCS/UMTS HIGH IP3 RFIC DOWNCONVERTER, 1.4 - 2.3 GHz Typical Applications Features The HMC421QS16 / HMC421QS16E is ideal for: Input IP3: +19 dBm • GSM, GPRS & EDGE Infrastructure Integrated IF & LO Amps: +10 dBm LO • CDMA, WCDMA Infrastructure Conversion Gain: 9 dB • PHS & PDC Infrastructure Noise Figure: 9 dB Single Positive Supply: +5V @ 60 mA Functional Diagram General Description The HMC421QS16 & HMC421QS16E are high linearity down-converter receiver ICs suitable for PCS/UMTS infrastructure applications. The receiver IC is designed to support UMTS applications where a high third order intercept point (OIP3) 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 8 dB and 9 dB typical single side band noise. The IC operates from positive +5V rails and consumes 60 mA of current. The design requires no external Baluns. The mixer supports IF frequencies between 50 MHz and 300 MHz.
