General Description

: TQ1422 is a quadband capable TX bandpass filter for GSM850/E-GSM/DCS1800/PCS1900 applications.

The integrated passive filter provides an optimum interface between the TQM7M4011/4012/4014 Power Amplifier Modules and direct conversion transceiver with balanced outputs.

TQ1422 replaces up to 17 surface-mount components [including 2 Baluns and/or SAW filter] typically required on the phone board to provide similar functionality.

Key Features

  • Low insertion loss High suppression of 2nd,3rd , 4th harmonics High selectivity Balanced to single-ended operation GSM Input: 310 Ohm balanced PCN/PCS Input: 80 Ohm balanced 50 Ω single-ended output impedances. Integrated DC-biasing to input MLP 10L 3x3 package (3x3mm²) Dimensions in mm.
