Product Description
The CV111-2 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
d
in reliable GaAs MESFET technology and
requires only a small 6x6 mm footprint.
Typical applications include frequenc
y
downconversion used in W-CDMA / IMT2000,
UMTS 2.5G and 3G mobile base transceiver
stations.
