DESCRIPTION
The AM2729-125 device is a high power silicon bipolar NPN transistor specifically designed for medium pulse S-Band radar output and driver applications.
This device is characterized at 50 µsec pulse width and 10% duty cycle, but is capable of operation over a range of pulse widths, duty cycles and temperatures. Low RF thermal resistance, refractory/gold metallization and computerized automatic wire bonding techniques ensure high reliability and product consistency (including phase characteristics).
The AM2729-125 is supplied in the BIGPAC™ Hermetic Metal/Ceramic package with internal Input/Output impedance matching circuitry, and is intended for military and other high reliability applications.
