Lowell, MA — Tyco Electronics M/A-COM has announced a line-up of three high-power bipolar transistors designed for pulsed avionics and radar applications, ranging from 960 MHz to 1215 MHz. The MAPRST0912-50, MAPRST0912-350 and MAPR-000912-500S00 transistors are ideally suited for pulsed avionics applications such as air traffic control (ATC) systems, distance measurement equipment (DME) and identification friend or foe (IFF) systems.
The new devices are assembled in a hermetic, ceramic/metal package for high reliability and are optimized for Tactical Air Navigation or similar short pulse formats. Additionally, the transistors are characterized at 960, 1090 and 1215 MHz to ensure optimal performance across the entire avionics frequency spectrum.
The MAPRST0912-50 is a 50 W-peak Class C, silicon bipolar pulse power transistor designed specifically for driver stages in pulse power amplifier applications over the 960 to 1215 MHz bandwidth. It is designed to have a minimum gain of 9.0 dB with 40 percent minimum collector efficiency (greater than 45 percent typical) on a 50-VDC supply.
The MAPRST0912-350 is similar to the MAPRST0912-50, and is rated at 350 W-peak with 40 W drive, and is ideal for intermediate amplifier stages. It features a minimum gain of 9.4 dB with 45 percent minimum collector efficiency (greater than 50 percent typical) on a 50-VDC supply.
The MAPR-000912-500S00 is rated at 500 W-peak and is ideal for amplifier final stages. It features a minimum gain of 9 dB with 45 percent minimum collector efficiency using a 50-V supply.
