0405-500L

0405-500L Rev A . 500 Watts - 32Volts, 1100µs, 26% UHF Pulsed Radar 400 - 450 MHz GENERAL DESCRIPTION The 0405-500L is an internally matched, COMMON EMITTER transistor capable of providing 500 Watts of pulsed RF output power in a push-pull configuration at one thousand and one hundred microsecond pulse width twenty –six percent duty factor across the frequency band 400-450 MHz. This hermetically sealed transistor is specifically designed for medium pulse radar applications. It utilizes gold metallization and diffused emitter ballasting to provide high reliability and supreme ruggedness. 0405-500L CASE OUTLINE 55SL, STYLE 2 ABSOLUTE MAXIMUM RATINGS Maximum Power Dissipation @ 25oC1 Maximum Voltage and Current BVces Collector to Emitter Voltage BVebo Emitter to Base Voltage Ic Collector Current Maximum Temperatures Storage Temperature Operating Junction Temperature 800 Watts 65 Volts 3.5 Volts 50 Amps - 65 to + 200oC + 200oC ELECTRICAL CHARACTERISTICS @ 25 OC SYMBOL Pout Pg ηc Pd VSWR1 CHARACTERISTICS Power Out (Note 2) Pulsed Power Gain Collector Efficiency Pulse Amplitude Droop Load Mismatch Tolerance TEST CONDITIONS F = 400-450 MHz Vcc = 32 Volts, Pulse Width = 1100 µs Duty = 26 % As above F = 425MHz, Po =500W MIN 500 9.5 50 10 0.6 2:1 TYP MAX UNITS Watts dB % dB FUNCTIONAL CHARACTERISTICS @ 25 OC Bvces Ices Iebo Hfe θjc2 Collector to Emitter Breakdown Collector to Emitter Leakage Emitter to Base Leakage Current DC Current Gain Thermal Resistance Ic = 150 mA Vce = 36 Volts Veb = 1.0 Volts Vce = 5 V, Ic = 1000mA Rated Pulse Condition 65 35 25 8 0.33 o Volts mA mA C/W Issue Nov. 2006 Note 1: Pulse width = 1100 us, duty = 26% Note 2: Power Input = 55 Watts Peak Pulsed(Max) Microsemi reserves the right to change, without notice, the specifications and information contained herein.
