SP10T ANTENNA SWITCH MODULE

The RF8889A Antenna Switch Module offers very low insertion loss along with

excellent linearity performance. The RF8889A is ideal for multi-mode GSM, EDGE,

CDMA, WCDMA, LTE and TD-SCDMA applications. This module integrates low pass

filtering on the GSM transmit paths thus avoiding the need for external harmonic

attenuation. The RF8889A is compatible with +1.8V control logic and is packaged

in a compact 3.0mmx3.8mm, 26-pin, QFN package. RF8889A does not require

external DC blocking capacitors enabling solution size reduction.
