UF2820P

Overview

The UF2820P is an N-channel enhancement mode RF MOSFET transistor manufactured by MACOM Technology Solutions. It utilizes a DMOS structure and operates within the 100 MHz to 500 MHz frequency range. The device is rated for a drain-source voltage of 65 V and delivers 20 W of output power at 28 V. Key electrical characteristics include a forward transconductance of 1.6 S, a power gain of 10 dB, and a drain efficiency of 50% at 500 MHz. It features low capacitances (CISS: 14 pF, COSS: 10 pF) and supports a load mismatch tolerance of 20:1.

Procurement Notes

Verify the specific datasheet revision against the manufacturer's official documentation before procurement. Confirm that the required operating conditions align with the absolute maximum ratings provided in the technical specifications. Ensure compatibility with the specified test fixture assembly for accurate performance validation during integration.

Selection Notes

Select this component for applications requiring high linearity and broadband performance between 100 MHz and 500 MHz. Consider the thermal resistance and junction temperature limits when designing the heat dissipation system. Evaluate the impedance matching requirements based on the typical device impedances provided in the datasheet for optimal power transfer.

Part Context

This part belongs to the MACOM RF Power MOSFET Transistor family. It is specifically engineered for high-power RF applications where wide bandwidth and robust load tolerance are critical. The device is distinct from lower-power variants in its ability to sustain 20 W output while maintaining stable gain and efficiency across the specified frequency spectrum.

Replacement Considerations

Consult the official MACOM product portfolio for direct substitutes. Verify that any alternative component matches the 20 W output power, 100-500 MHz frequency range, and 65 V drain-source voltage ratings. Ensure pinout compatibility and thermal management requirements are identical to avoid redesigning the host circuitry.
