GENERAL DEscriptION
The SGM72112A is a single-pole/twelve-throw (SP12T) antenna switch, which supports from 0.1GHz to 3.0GHz. The device features low insertion loss and high isolation, which make it suitable for high linearity receiving applications. It also has the advantage of high linearity performance. The SGM72112A is not subject to cellular interference and is applied to multi-mode and multi-band LTE mobile phones.
The SGM72112A has the ability to integrate SP12T RF switch and MIPI controller on silicon-on-insulator (SOI) process. Internal driver and decoder for switch control signals are offered by the 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 SGM72112A is available in a Green UTQFN-2.5×2.5-20L package.
