PT9785

The PT9785 is designed as one kind of SSB power transistors which primarily for wideband,large-signal output and driver amplifier stages in the 2 to 30 MHz frequency range.It is produced by Motorola semiconductor.Also PT9785 has some features:(1)deisgned for class C or class AB power amplifiers;(2)specified 28 volt,28 MHz characteristics:output power--100 watts;power gain--14 dB,min;(3)gold metallization for improved reliability;(4)diffused ballast resistors;(5)100% tested for load mismatch at all phase angles with 1 VSWR.

The absolute maximum ratings of the PT9785 can be summarized as:(1)collector-emitter voltage:20 vdc;(2)collector-base voltage:40 vdc;(3)emitter-base voltage:4 vdc;(4)collector current-continuous:25 adc;(5)operating junction temperature:200;(6)storage temperature range:-65 tp +150;(7)total device dissipation @ Tc=25:350 watts and derate above 25:2 W/.If you want to know more information about this type ,please download the datasheet in www.seekic.com and www.chinaicmart.com
