TQ9142

The TQ9142 is desighed as one kind of high-efficiency 3-stage amps power amplifier IC.It is a highly efficient power amplifier developed for portable terminals operating in the AMPS cellilar band(824-849 MHz).The amplifier TQ9142 is packaged in a space-efficient SOIC-16 palstic package with specially modified central thermal tabs.There tabs provide reliable operation for the 1.4 watt power output.The TQ9142 is deaigned to require minimal external circuitry for matching or bias,simplifying design and keeping board space and cost to a minmum.

Features of the TQ9142 are:(1)60% drain efficiency;(2)+31.5 dBm power output;(3)4.0 V to 6.0 V operation;(4)SO-16 package;(5)50 matched input;(6)monolithic power amp.It also can be used in analog cellular handsets and CDPD terminals.The absolute maximum ratings can be summerized as:(1)DC power supply:8.0 V;(2)DC gate voltage:-5.0 V;(3)RF input power:TBD dBm;(4)storage temperature:-55 to +150;(5)operating temperature:-40 to +100.If you want to know more information of TQ9142,please visit our website and download the datasheet.
