com CV211-2 Product Features • High dynamic range downconverter with integrated LO and IF amplifiers The Communications Edge TM UMTS-band Dual-Branch Downconverter Product Information Product Description The CV211-2 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.
It provides high dynamic range performance in a low profile 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 GaAs MESFET and InGaP HBT technology.
Typical applications include frequency downconversion used in W-CDMA 2.
5G and 3G mobile base transceiver stations.
