DESCRIPTION:

DESCRIPTION:

The MSC1550M is a high power pulsed transistor specifically designed

for IFF avionics applications. It is designed for operation under short

pulse width and low duty cycle pulse conditions and is capable of

withstanding a minimum 25:1 load mismatch at rated RF conditions.

Internal impedance matching and gold metallization ensure high

product reliability and consistency.
