DESCRIPTION

The AM1011-400 device is a high power Class
C transistor specifically designed for TCAS and
Mode-S pulsed output and driver applications.

This device is designed for operation under moder­ate pulse width and duty cycle pulse conditions
and is capable of withstanding 15:1 output VSWR
at rated RF conditions. Low RF thermal resistance
and computerized automatic wire bonding tech­niques ensure high reliability and product consist­ency.

The AM1011-400 is supplied in the BIGPAC Her­metic Metal/Ceramic package Input/Output match­ing structures.
