PT9730 series

The PT9730 series is designed as one kind of UHF power transistors which primarily for wideband,large-signal output and driver amplifier stages in the 30 to 200 MHz frequency range.It is produced by Motorola semiconductor.Also PT9730 series has some features:(1)deisgned for class C or class AB power amplifiers;(2)specified 28 volt,175 MHz characteristics:output power--4 to 25 watts;power gain--10 to 13 dB,min;collector efficiency--60%,min;(3)gold metallization for improved reliability;(4)diffused ballast resistors.

The absolute maximum ratings of PT9730 series can be summarized as:(1)collector-emitter voltage:35 vdc;(2)collector-base voltage:60 vdc;(3)emitter-base voltage:4 vdc;(4)collector current-continuous:1,1.25,2.5 and 4 adc;(5)operating junction temperature:200;(6)storage temperature range:-65 tp +150.If you want to know more information about this type ,please download the datasheet in www.seekic.com and www.chinaicmart.com
