| MS2552 RF PRODUCTS DIVISION RF & MICROWAVE TRANSISTORS PRODUCT PREVIEW DESCRIPTION KEY FEATURES W W W.Microsemi .COM The MS2552 device is a high power pulsed transistor specifically designed for DME/TACAN avionics applications. This device is capable of withstanding an infinite load VSWR at any phase angle under full rated conditions. Low RF thermal resistance and semiautomatic bonding techniques ensure high reliability and product consistency. The MS2552 is housed in the industry-standard AMPAC metal/ceramic hermetic package with internal input/output matching structures. IMPORTANT: For the most current data, consult MICROSEMI's website: http://www.microsemi.com Refractory/Gold Metallization Emitter Ballasted Ruggedized VSWR :1 Capability Input/Output Matching Overlay Geometry Metal/Ceramic Hermetic Package POUT = 325 W Min.
