Transcription

1 Technical Data Reference Design Library Power Field Effect Transistors N-Channel Enhancement-Mode Lateral MOSFETs Device Characteristics (From Device Data Sheet) Designed for broadband commercial and industrial applications at frequencies up to 1 MHz. The high gain and broadband performance of these devices makes them ideal for large- signal, common- source amplifier applications in 26 volt base station equipment. Typical Two- Tone Performance at 94 MHz, 26 Volts Output Power 6 Watts PEP Power Gain 17 db Efficiency 4% IMD -31 dbc Integrated ESD Protection Designed for Maximum Gain and Insertion Phase Flatness Capable of Handling 1:1 26 Vdc, 94 MHz, 6 Watts CW Output Power Excellent Thermal Stability Characterized with Series Equivalent Large- Signal Impedance Parameters Low Gold Plating Thickness on Leads. L Suffix Indicates 4µ Nominal.

The reference design is tuned for performance at 6 watts average output power, V DS = 26 volts, and. REFERENCE DESIGN LIBRARY TERMS AND CONDITIONS Freescale is pleased to make this reference design available for your use in development and testing of your own product or products, without charge. The reference design contains easy- to- copy, fully functional amplifier designs. Where possible, it consists of no tune distributed element matching circuits designed to be as small as possible, includes temperature compensated bias circuitry, and is designed to be used as building blocks for our customers. HEATSINKING When operating this fixture please provide adequate heatsinking for the device. Excessive heating of the device will prevent repeating of the included measurements. NONLINEAR SIMULATION To aid the design process and help reduce time to market for our customers, Freescale provides device models for several commercially available harmonic balance simulators. Our model Library is available for all major computer platforms supported by these simulators.
