description

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). It 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.

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
