Product Description

The TQ9147 is a high efficiency two stage GaAs MESFET power amplifier IC intended for use in AMPS (IS-19) applications that operate in the US Cellular (824 - 849 MHz) band. The TQ9147 requires minimal external RF circuitry and operates from a 4.8-Volt supply. With its flexible, off-chip, single component output matching circuit, the TQ9147 is suitable for use in other applications near the cellular band, such as 900 MHz ISM applications.

The TQ9147 utilizes a space saving SO-16 plastic package that minimizes board area and cost.
