Matched for 50 W RF interfaces
XeMOS FET Technology
Stable Performance
QuikPAC System Compatible
QuikClip or Flange Mounting
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 VGS to set the desired quiescent current.
