HMC597LP4 / 597LP4E v03.0907 SiGe WIDEBAND DIRECT DEMODULATOR RFIC, 100 - 4000 MHz Typical Applications Features The HMC597LP4 / HMC597LP4E is suitable for various modulation systems: High Linearity: +25 dBm IIP3 & +60 dBm IIP2 • Cellular/PCS/3G High Integration: On-Chip RF Balun Low Noise Figure: 15 dB • Base Stations & Repeaters • GSM/GPRS, WCDMA & TD-SCDMA • WiMAX, WiBro & Fixed Wireless Functional Diagram DEMODULATORS - SMT 10 General Description The HMC597LP4(E) are highly integrated SiGe wideband direct conversion I/Q Demodulator RFICs which are ideal for high dynamic range receivers operating from 100 - 4000 MHz in cellular and broadband wireless infrastructure applications. Providing a very high level of integration compared with discrete solutions, the HMC597LP4(E) features an on-chip RF balun which allows for singled ended RF input. An off-chip capacitor allows the reconfiguration of the RF port to operate over the whole 100 - 4000 MHz band without additional off-chip components. Also ideal for software radio and other multi-band receivers, the HMC597LP4(E) demodulator is housed in a compact 4 x 4 mm SMT QFN package and delivers exceptionally high dynamic range. The LO requires -6 to +6 dBm and can be driven in single-ended mode. The I and Q output ports are differential with an output impedance of 400 Ohms, allowing direct connection to channel filters and ADCs. This device is optimized for a supply voltage of +4.5V to +5.5V and consumes 200 mA @ +5V supply. Electrical Specifi cations, See Test Conditions on following page herein.
