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

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.
