Description

The CXG1027TM is a two-stage driver amplifier for

800 MHz and 1.5 GHz PDC. This is used to amplify

the transmission-side power of the RF signal.

Features

• Ultraminiature package (10 pin TSSOP)

• Low voltage operation

: 2.9 V (Min.)

• Low current consumption

: 45 mA (Typ.)

• High gain

: 27.5 dB (Typ.) (for 1.5 GHz)

29.5 dB (Typ.) (for 800 MHz)

• Low distortion (Adjacent channel leak power ratio)

: –50 dBc (Typ.) (30 kHz offset)

–69 dBc (Typ.) (50 kHz offset)

• Positive power supply operation

• Supports both 800 MHz and 1.5 GHz by the

external matching circuit

Applications

Power amplification between the quadrature

modulator IC for 800 MHz/1.5 GHz PDC transmitter

(approx. –15 dBm output) and the power module or

power amplifier MMIC (approx. +10 dBm input)
