CV221-2A Datasheet | WJ Communication

.. - 2.7 GHz Dual-Branch Downconverter Product Features - High dynamic range downconverter with integrated LO and IF amplifiers Product Description The CV221-2A is a dual-channel high-linearity downconverter designed to meet the demanding performance, functionality, and cost goals of current and next generation mobile infrastructure basestations and repeaters. It provides high dynamic range performance in a low profile Ro HS-pliant/lead-free surface-mount leadless package that measures 6 x 6 mm square. It is ideally suited for high dynamic range receiver front ends using diversity receive channels. Functionality includes frequency conversion and IF amplification, while an integrated LO driver amplifier powers the passive mixer. The MCM is implemented with reliable and mature Ga As MESFET and In Ga P HBT technology. Typical applications include frequency downconversion used in 3G W-CDMA and Wi Max basestation transceiver or repeater applications.
