Dimensions in mm
Application:
TX H2,H3,H4-Bandpass Filter / Balun for GSM850/900 and DCS/PCS systems
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.
