摘要
A radio frequency (RF) phase shifter having an RC-CR circuit that includes a first capacitor having a first capacitor node and a second capacitor node and a first resistor coupled between the first capacitor node and a ground. The RC-CR circuit also includes a second resistor having a first resistor node and a second resistor node and a second capacitor coupled between the first resistor node and the ground. The RF phase shifter generates arbitrary phase shift by using a scheme of adding two perpendicular vectors with variable gains (or amplitudes).
