Description

The TQ9142B is a highly efficient 3-stage power amplifier developed for handsets and portable terminals operating in the AMPS cellular band (824 to 849 MHz). The TQ9142B is designed to require minimal external circuitry for matching or bias, simplifying design and keeping board space and cost to a minimum. Access to each stage's gate and drain voltages is provided for maximum flexibility in selection of output power control method, making output power vs. efficiency tradeoffs, or for implementing alternative biasing schemes. The amplifier TQ9142B is packaged in a SOIC-16 plastic package with specially modified central thermal tabs. These tabs provide reliable operation for the 1.4 Watt power output.
