† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

The TRF4000 personal communications system (PCS) RF downconverter is a gallium arsenide (GaAs) integrated circuit housed in a 14-pin plastic surface-mount, thin-shrink small outline package (TSSOP). TRF4000 is suitable for 1.9-GHz code-division multiple-access (CDMA) applications and is composed of a local oscillator (LO) buffer amplifier, an RF preamplifier, a mixer, and a differential IF amplifier.
