TPR400

Overview

The TPR400 is a high-power bipolar transistor designed for pulsed avionics applications operating within the 1030 to 1090 MHz frequency range. It delivers a power output of 400 Watts with a maximum voltage rating of 50 Volts. The component utilizes a common base configuration, which is standard for high-frequency RF power amplification in radar and communication systems. This device is engineered to handle significant pulsed power demands while maintaining stability in demanding electromagnetic environments typical of aerospace and defense electronics.

Feature Summary

Capable of delivering 400 Watts of pulsed RF power output
Operates effectively within the 1030-1090 MHz L-band spectrum
Designed specifically for avionics and radar system integration

Applications

Pulsed radar transmitters in military aircraft
Air traffic control radar systems
Avionics communication equipment requiring high-power RF generation

Part Context

This component belongs to the family of high-power RF transistors manufactured by Microsemi Corporation (now part of Microchip Technology). These devices are critical for generating the high-energy pulses required in active electronically scanned arrays and traditional pulse-Doppler radar systems used in modern aviation.

Replacement Considerations

Publicly confirmed substitute part numbers for the TPR400 are not available in the provided documentation. Engineers should consult official Microchip/Microsemi cross-reference guides or contact technical support directly for validated equivalent components.
