QuikPAC Module Data

Class AB Power Stage

General description:

The QPP-021 QuikPAC™ RF power module is an impedance 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. The gate terminal is connected directly to the control voltage pin, allowing direct control of the bias. The user must supply the proper value of VGS to set the desired quiescent current.
