SGM21102B 0.3GHz to 6.0GHz SPDT Switch
GENERAL DESCRIPTION
The SGM21102B is a single-pole/double-throw (SPDT) switch for mode switching in WLAN applications. The device features low insertion loss and high isolation. The product uses advanced switching technologies and supports 0.3GHz to 6.0GHz.
The SGM21102B has the ability to integrate SPDT RF switch and GPIO controller on an SOI chip. Internal driver and decoder for switch control signals are offered by the GPIO controller, which makes it flexible in RF path band and routing selection.
No external DC blocking capacitors are required on the RF paths as long as no external DC voltage is applied, which can save PCB area and cost.
The SGM21102B is available in a Green XTDFN-1×1-6AL package.
APPLICATIONS
WLAN 802.
