Abstract:
A radio frequency antenna switch includes an antenna port, a radio frequency signal port, and at least one branch coupled to the antenna port or the radio frequency signal port, where each branch includes multiple transistors which are coupled in a stack manner, channel width to length ratios of a preset number of transistors in the transistors progressively decrease in a direction away from the antenna port, where the preset number is less than or equal to the total number of the transistors. With the radio frequency antenna switch, capacitances of the preset number of transistors close to the antenna port increase, and distributed voltages that these transistors close to an antenna end in an off state need to bear are reduced.

Claim (Index 11):
The switch of  claim 2 , wherein each transistor in the transistors has a multi-finger structure comprising at least one first finger used as a source and at least one second finger used as a drain, each first finger being coupled to a common source point, each second finger being coupled to a common drain point, each first finger being coupled, using a plurality of first vias, to a source corresponding to the first finger, each second finger being coupled, using a plurality of second vias, to a drain corresponding to the second finger, and numbers of the first vias and the second vias of the preset number of transistors in the transistors progressively decrease in the direction away from the antenna port.
