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. High value inductors to
supply open collector modulators are integrated.
