BGS14WMA9

Active and preferred

BGS14WMA9 is a Single Pole Four Throw (SP4T) diversity switch which is specifically designed for WLAN and Bluetooth applications in a very compact 9 pin package with very small size of only 1.1 x 1.1 mm2 and thickness of 0.55 mm. Any of the 4 ports can be used as termination of the diversity antenna handling up to 26 dBm. Unlike GaAs technology, external DC blocking capacitors at the RF ports are only required if DC voltage is applied externally.BGS14WMA9 RF switch is manufactured in Infineon’s patented MOS technology, offering the performance of GaAs with the economy and integration of conventional CMOS including the inherently higher ESD robustness.
