DESCRIPTI ON
The AM81214-030 device isa highpowertransistor
specifically designed for L-Band Radar pulsed
driver applications.
The device is capable of operation over a wide
range of pulse widths, duty cycles and tempera-
tures and is capable of withstanding∞:1 output
VSWR at rated RF conditions. Low RF thermal
resistance and computerized automatic wire bonding techniques ensure high reliability and product
consistency.
The AM81214-030 is supplied inthe IMPAC Hermetic M etal/ Ceramic package with i nternal
Input/Output matching structures.
