UMIL80

Overview

The UMIL80 is an NPN bipolar RF transistor manufactured by Microsemi Corporation, designed for broadband applications within the 200 MHz to 500 MHz frequency range. It features a maximum power rating of 220W and a collector-emitter breakdown voltage of 31V. The device exhibits a transition frequency between 200MHz and 500MHz with a gain of 9dB to 9.5dB. Packaged in the 55HV format, it supports an operating temperature up to 200°C. This component is currently classified as obsolete.

Feature Summary

• Double input matched common emitter configuration
• Broadband design optimized for 200-500 MHz band
• High power handling capability of 220W

Applications

• RF amplifier circuits
• Broadband communication systems
• Military and aerospace electronics

Procurement Notes

Verify part status carefully as the UMIL80 is listed as obsolete. Confirm availability through authorized distributors or surplus suppliers. Ensure compatibility with existing 55HV packaging requirements. Check for valid manufacturer documentation before integration into new designs due to end-of-life status.

Selection Notes

Select this component only if the specific 200-500 MHz frequency range and 220W power rating align with system requirements. Consider the obsolete status when planning long-term production cycles. Evaluate thermal management needs given the 200°C operating limit and high power dissipation characteristics inherent to this RF transistor class.
