HMC420QS16 / 420QS16E v03.0810 MIXERS - DOWNCONVERTERS - SMT 9 CELLULAR RFIC DOWNCONVERTER, 0.7 - 1.0 GHz Typical Applications Features The HMC420QS16 / HMC420QS16E is ideal for: +15 dBm Input IP3 • GSM & CDMA Infrastructure Integrated IF & LO Amps: 0 dBm LO • GPRS & EDGE Infrastructure Conversion Gain: 12.5 dB • Wireless Data/CDPD Noise Figure: 13 dB Single Positive Supply: +5V, 52 mA Functional Diagram General Description The HMC420QS16 & HMC420QS16E are linear downconverter receiver ICs suitable for cellular infrastructure applications from 0.7 - 1.0 GHz. An integrated mixer coupled with a high dynamic range IF amplifier achieves an input intercept point (OIP3) of +15 dBm, and an input P1dB of +1 dBm. The converter provides a gain of 12.5 dB and 13 dB typical single side band noise. The IC operates from positive +5V rails consuming 52 mA of current while requiring only 0 dBm LO drive. The design requires no external baluns, and minimal off chip components. The HMC420QS16 & HMC420QS16E have the same package footprint as the HMC380QS16G & HMC421QS16 1.4 - 2.3 GHz downconverter ICs.
