The ETC1.6-4-2-3 is a balun transformer manufactured by Tyco Electronics. This balun is designed to convert between balanced and unbalanced electrical signals. Baluns are commonly used in various electronic circuits to match impedances, isolate grounds, and suppress common-mode noise. They ensure efficient signal transmission and reception in applications involving different types of transmission lines or antennas.

Applications

• Antenna impedance matching
• Balanced to unbalanced signal conversion
• Cable television (CATV) systems
• Wireless communication systems
• Differential signal transmission
• Broadcast video equipment

Features

• Wide bandwidth
• Low insertion loss
• High return loss
• Excellent common-mode rejection
• Compact size
• Surface mount technology (SMT)

Benefits

• Improved signal transmission efficiency due to impedance matching.
• Reduced signal loss due to low insertion loss.
• Minimized signal reflections due to high return loss.
• Suppression of unwanted noise due to excellent common-mode rejection.
