HMC334LP4 / 334LP4E v00.0407 8 SiGe WIDEBAND DOWNCONVERTER, 0.8 - 2.7 GHz Typical Applications Features The HM334LP4 / HMC334LP4E is ideal for Wireless Infrastructure Applications: Conversion Loss: 0 dB • Basestations & Repeaters Single-Ended LO Drive: -6 dBm • GSM, GPRS & Edge Input IP3: +26 dBm • CDMA, W-CDMA & TD-SCDMA SSB Noise Figure: 10.5 dB • WiMAX & WiBro On-Chip RF Balun LO to RF Isolation: 48 dB MIXERS - SMT RoHS Compliant 4x4mm QFN Package General Description Functional Diagram The HMC334LP4 & HMC334LP4E are low noise, wideband downconverter RFICs which are ideal for Cellular/3G and WiMAX/4G applications from 0.8 to 2.7 GHz. The LO input accepts drive levels from -6 to +6 dBm while the RFIC provides 48 dB of LO to RF isolation, and 0 dB conversion loss. The HMC334LP4(E) will support an IF output bandwidth of up to 600 MHz and consumes only 173mA from a +5.0V supply. This wideband active mixer also provides excellent performance in the presence of high level “Blocker” signals, making it ideal for receiver applications in demanding environments.
