Microsemi intros 150W driver transistor

IRVINE, US: Microsemi Corp., a leading manufacturer of high performance analog mixed signal integrated circuits and high reliability semiconductors, has released a 150W power driver transistor for Mode-S avionics transmitters.

Designated the MDS150, new driver transistor is designed to complement Microsemi's MDS Series of high power transistors for Mode-S avionics applications.

"With the success of our high power Mode-S transistors, we saw the need to design a driver product optimized for Mode-S pulsing. It exemplifies our commitment to support the avionics market by investing in new product developments," said Jim Zazkowski, Manager of Microsemi's Avionics & Defense Communications products in Santa Clara, California. "Taken together, our Mode-S series of devices (MDS150, MDS400, MDS800 and MDS1100) provide avionics designers with a total transmitter solution,," he added.

The MDS150 provides 150W of output power at 1030/1090MHz with Mode-S pulsing (0.5uS on/off x128 burst). This Class C biased, bipolar transistor runs on V(cc) = 50V making it easy to use with existing power supplies running on 50-52V. The die utilizes gold metallization and integral emitter ballast resistors for maximum reliability.

Production quantities are available immediately through authorized distributors or direct from the factory.
