QuikPAC Module Data

Class AB Power Stage

General description:

The QPP-018 QuikPAC™ RF power module is a matched Class AB amplifier stage designed for use in the output stage of linear RF power amplifiers for cellular base stations. The power transistors are fabricated using Xemod’s advanced design LDMOS process. This unit has a factory set, regulated and temperature compensated gate bias, eliminating the need for the user to provide adjustable gate bias voltage circuits and make individual bias adjustments during stage alignment.
