XeMOS FET Technology
Stable Performance
QuikPAC System Compatible
Flange Mounting
The QPP-029 QuikPAC™ RF power module is an impedance
matched Class AB amplifier stage designed for use cellular repeater
systems. 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 VGS to set the desired quiescent
current.
