The TRF4002 personal communications system (PCS) RF power amplifier is a gallium arsenide (GaAs), integrated circuit housed in a 20-pin plastic surface-mount, thin-shrink small outline package (TSSOP). The package has a solderable pad that improves the package thermal performance by bonding the pad to an external thermal plane. The pad also acts as a low-inductance electrical path-to-ground and must be electrically connected to the printed-circuit board (PCB) ground plane as a continuation of the regular package terminals that are designated GND. The integrated circuit is suitable for 1.9-GHz code-division multiple-access (CDMA) applications.
