摘要:
Contrary to phase shifters which require complimentary polarity control voltages, a phase shifter may be driven with a single polarity control voltage. The phase shifter comprises an input node in communication with both a high pass network and a low pass network which are both in communication with an output node, where the phase shifter further comprises a first single pole double throw switch and a second single pole double throw switch configured to selectively pass an RF signal from the input node to the output node by way of one of said high pass network and said low pass network. Furthermore, the first and second single pole double throw switches are configured to select between the high pass network and the low pass network based on a single control signal having a voltage greater than or less than a reference voltage.
