Product Overview
TA947GG is a surface acoustic wave (SAW) bandpass filter developed by TST Tai-Saw. Designed for 947.5MHz GSM communication frequency band, it features 25MHz pass bandwidth, low 3.5dB maximum insertion loss and standard 50Ohm system impedance. Adopting compact 3.0×3.0mm 6-pin SMD packaging, it suppresses out-of-band interference efficiently, ensures clean RF signal transmission for wireless modules, base station front-end and remote keyless entry equipment.
Core Advantages
Low Insertion Loss
Max 3.5dB insertion loss reduces RF signal attenuation, guarantee stable signal strength for wireless devices.
Standard 50Ω Impedance Matching
50Ohm input & output impedance matches most RF chips, no extra matching circuit required.
Compact Miniature SMD Package
3030 6-pin tiny footprint saves PCB layout space for portable wireless modules.
High Out-of-Band Rejection
Excellent suppression for interference signals outside 935MHz~960MHz pass band, anti-noise performance outstanding.
Wide Operating Temperature Range
Stable electrical performance from -40℃ to +85℃, fit industrial & outdoor communication equipment.
