CV210-1

CV210-1 Cellular-band Dual-Branch Downconverter The Communications Edge TM Preliminary Information Product Features • High dynamic range downconverter with integrated LO driver and IF amplifiers • Dual channels for diversity • +27 dBm Input IP3 • +12 dBm Input P1dB • 11.5 dB Noise Figure • RF: 806 - 915 MHz • IF: 70 - 120 MHz • Low-side LO downconverter • Single supply operation (+5 V) • 6 x 6 mm QFN SMT package CV Product Description The CV210-1 is a dual-channel high-linearity downconverter designed to meet the performance, functionality, and cost goals of current and next generation mobile infrastructure basestations. It is ideally suited for high dynamic range receiver front ends using diversity receive channels. The module is implemented in reliable GaAs MESFET technology and requires only a small 6x6 mm footprint. Typical applications include frequency downconversion used in CDMA/GSM/TDMA, CDMA2000, W-CDMA, and EDGE 2.5G and 3G mobile base transceiver stations.
