A vector attenuator that uses PIN diodes as the controlling elements to produce good intermodulation performance
A Vector Attenuator for Feedforward Amplifier and RF Predistortion Use Micro-Precision Technologies Inc. (MPT) Salem, NH Feedforward amplifiers and RF predistortion circuits used in cellular radio base stations require gain and phase adjustment in their cancellation loops. The classical approach to this requirement has been through the use of...
