TX-RX Diversity Switch
Description:
CSH210 is a general purpose single-pole,
single-throw switch device designed for
mobile communications applications such as
cellular and PCS mobile phones, ISM bands,
GPS receivers, L-band satellite terminals,
WLAN and pagers. The device is based on
pHEMT technology and exhibits very low
insertion loss and high intermodulation
performance.
The CSH210 does not need a supply voltage
and switching is accomplished with a positive
control voltage. The device exhibits excellent
VSWRs and isolation as well. It is useable
from DC to 3 GHz.
Applications:
