QPP-003 60W, 869-894 MHz Class AB Power Stage QuikPAC Module Data General description: Features: The QPP-003 QuikPAC™ RF power module is an impedance matched Class AB amplifier stage designed for use in the driver or output 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.

VGS may be safely set to any voltage in the range listed in the table. This permits a wide range of quiescent current to be used. Since the operating characteristics of the module will vary as IDQ changes, the bias setting will depend on the application. The data provided in the Performance section of this data sheet was obtained with IDQ set to a value within the range listed (a nominal value ±10%). This particular value was chosen to optimize gain, IMD performance, and efficiency simultaneously. Gate voltage must be applied coincident with or after application of the drain voltage to prevent potentially destructive oscillations. Bias voltages should never be applied to a module unless it is terminated on both input and output. The VGS corresponding to a specific IDQ will vary from module to module and may vary between the two sides of a dual RF module by as much as ±0.10 volts. This is due to the normal die-to-die variation in threshold voltage of LDMOS transistors. Since the gate bias of an LDMOS transistor changes with device temperature, it may be necessary to use a VGS supply with thermal compensation if operation over a wide temperature range is required. 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. Package Styles This model is available in both B1 (H10536) and B1F (H11029) package styles. Style B1F is shown for reference. Please see the applicable outline drawing for specific dimensions.
