Description
AI
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 ron 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 4x4 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.Included as part of Hittite's Wideband DCR Solution: HMC6383ApplicationsCellular/PCS/3GBase Stations & RepeatersGSM/GPRS, WCDMA & TD-SCDMAWiMAX, WiBro & Fixed Wireless
