| www..com TQ1422 (Advanced data sheet) GSM850/900 and DCS1800/PCS1900 Tx - Bandpass Filter Package Outline: 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 single-ended output impedances. Integrated DC-biasing to input MLP 10L 3x3 package (3x3mm) 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.
