Product Description
The CV211-2 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 W-CDMA / IMT2000,
UMTS 2.5G and 3G mobile base transceiver
stations.
