Product Description
The CV110-1 is a 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. The module is implemente
in reliable GaAs MESFET technology and
requires only a small 6x6 mm footprint.
Typical applications include frequenc
downconversion used in CDMA/GSM/TDMA,
CDMA2000, W-CDMA, and EDGE 2.5G and
3G mobile base transceiver stations.
