Preliminary 35W, 824-849MHz
QuikPAC Module Data Class AB Driver Stage
General description:
The QPP-030 QuikPAC™ RF power module is an impedance
matched Class AB amplifier stage designed for use in cellular
repeater systems. The power transistor is 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.

Notes:
This GR-version QuikPAC module has an internally regulated gate voltage that is preset at the factory. A voltage of
+12VDC (±1V) should be applied to the gate lead (pin 3). No further adjustment is required. The gate voltage is thermally
compensated for operation over the temperature range listed in the data sheet. Although the module will operate with
lower voltages applied, the internal regulator is not functioning and the specified performance may not be achieved.
Gate voltage must be applied coincident with or after application of the drain voltage to prevent potentially destructive
oscillations. Bias voltages sh ould never be applied to a module unless it is terminated on both input and output.
The quiescent current set during manufacture will be within the range specified in the Performance section (nominal
±10%) and is selected to balance IMD, input return loss, and efficiency. This setting is suitable for most applications.
Modules with different optimization profiles are available by special order.
Internal RF decoupling is included on all bias leads. No additional bypass elements are required, however some
applications may require energy storage on the drain leads to accommodate time -varying waveforms.
The RF leads are internally protected against DC voltages up to 100V. Care should be taken to avoid video transients that
may damage the active devices.
