General description:
The
QPP-008 QuikPAC
RF power module is an impedance
matched Class AB amplifier stage designed for use in the driver stage
of linear RF power amplifiers for cellular base stations. The power
transistor is 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 V
GS
to set the desired quiescent current.
