description
NC – No internal connection
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.
The TRF4002 is a power amplifier that uses a two-stage topology with an on-/off-chip output inductor and
impedance matching network to minimize cost. It is suitable for use in mobile systems that require high linearity.
It can deliver 27.5-dBm typical output power optimized for minimum adjacent channel power.
These devices have no built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the gates.
