Abstract:
1. A phase shifter comprising: a first single pole double throw switch for receiving a radio frequency (RF) signal at an input node, a voltage reference signal, and a single control signal, said first single pole double throw switch for providing said RF signal to one of a high pass network or a low pass network, wherein said first single pole double throw switch comprises a first transistor and a second transistor; and a second single pole double throw switch for receiving said voltage reference signal, said second single pole double throw switch for receiving said RF signal from said high pass network or said low pass network and providing said RF signal to an output node, wherein said first single pole double throw switch provides said RF signal from said input node to one of said high pass network or said low pass network in accordance with said single control signal and wherein said second single pole double throw switch provides said RF signal from one of said high pass network or said low pass network to said output node in accordance with said single control signal; wherein said voltage reference signal is provided to a source terminal and a drain terminal of said first transistor, wherein said single control signal is provided to a gate of said first transistor; and wherein said single control signal is provided to a source terminal and a drain terminal of said second transistor.
