Tyco Electronics M/A-COM has developed a Class C bipolar transistor capable of 1-kW peak output power at 1030 MHz. Designed for short-pulsed avionics applications, including IFF and TACAN systems, the 50-V power transistor provides minimum gain of 8 dB and more than 8.6 dB typical gain. The minimum collector efficiency is 45 percent and typically more than 50 percent. According to Andrew Tse, product line manager for Tyco Electronics M/A-COM Radar and Avionics, "The one-thousand-watt power rating on this new transistor can greatly enhance the range capabilities of new avionics systems. Additionally, the unique power capability of the product will contribute to more compact system designs, as one device can replace a pair of devices in the final amplifier circuit architecture." The M/A-COM MAPRST1w030-1KS is supplied in a hermetic, ceramic/metal package for high reliability and can tolerate a 10:1 load mismatch without damage or loss in performance. The bipolar sells for $393 in hundred quantities. Tyco Electronics M/A-COM (www.macom.com)
