Tyco Electronics Announces M/A-COM 1,000 Watt Bipolar Transistor for Avionics Applications

Transistor Ideally Suited for Tactical Air Navigation System and Similar Short Pulse Applications

LOWELL, Mass. - May 8, 2007 - Tyco Electronics today announced the M/A-COM MAPRST1030-1KS, a new 1,000 W peak, class C bipolar transistor designed for 1030 MHz pulsed avionics applications. The transistor is ideally suited to operate in IFF/TACAN (tactical air navigation system) or similar short pulse formats and features a minimum gain of 8.0 dB (>8.6 dB typical) with 45% minimum collector efficiency (>50% typical) on a 50Vdc supply.

"The one thousand watt power rating on this new transistor can greatly enhance the range capabilities of new avionics systems," said Andrew Tse, product line manager, Tyco Electronics M/A-COM Radar and Avionics. "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."

Designed for maximum durability, the M/A-COM MAPRST1w030-1KS is housed in a hermetic, ceramic/metal package for high reliability that can tolerate a 10:1 load mismatch without damage or loss in performance. M/A-COM brand driver stages for the MAPRST1030-1KS are also available, including the MRF10005, MRF10031 and MRF10150.

Pricing and Availability

The M/A-COM MAPRST1030-1KS is priced at $393 USD each in production quantities of hundreds. Pricing is subject to change.
