(Advanced data sheet)
GSM850/900 and DCS1800/PCS1900 Tx – Bandpass Filter
Package Outline:
Dimensions in mm
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)
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.
