APN1009: A varactor-controlled phase shifter for PCS base station applications

Posted: 12 Mar 2007 ?? ?Print Version ?Bookmark and Share

Keywords:power amplifier? voltage-controlled attenuator? voltage-controlled phase shifter? attenuator? phase shifter?

Power amplifiers in today's base stations use compensation techniques to reduce distortion. There are many well-known compensation techniques available, all relying on similar principles of phase and amplitude control. Thus, most (and possibly all) of the compensation techniques use the same control components: voltage-controlled attenuators and voltage-controlled phase shifters.
