MRF160

Overview

The MRF160 is an N-channel enhancement mode RF MOSFET designed for wideband large-signal output and driver applications from 30 MHz to 500 MHz. It guarantees performance at 28 V and 500 MHz, delivering 4.0 W of output power with a minimum gain of 16 dB and typical efficiency of 55%. The device features excellent thermal stability suitable for Class A operation and facilitates manual gain control, automatic level control (ALC), and modulation techniques. It includes low Crss of 0.8 pF typical at VDS = 28 V.

Feature Summary

• Designed primarily for wideband large-signal output and driver applications

Procurement Notes

Verify the specific datasheet revision (e.g., Rev. V1) when sourcing components, as MACOM reserves the right to make changes to product specifications without notice. Confirm that the intended application does not involve medical, life-saving, or life-sustaining systems, as these devices are explicitly excluded from such use cases by the manufacturer.

Selection Notes

Select this component for broadband designs requiring stable performance up to 500 MHz. The guaranteed 16 dB minimum gain and 4.0 W output power make it suitable for driver and output stages. Ensure the design accommodates Class A biasing to leverage the device's excellent thermal stability and modulation capabilities.
