Description
The AS186-302 is a GaAs FET IC SPDT non-reflective
switch packaged in a MSOP-8 exposed pad plastic
package for low cost, high isolation commercial
applications. Ideal building block for base station
applications where synthesizer isolation is critical. Typical
applications include GSM, PCS, WCDMA, 2.4 GHz ISM
and 3.5 GHz wireless local loop.
