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.
