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.
