RF High Rejection BroadBand Analog-to-digital Conversion Baluns

1. Convert current or voltage from unbalanced to balanced
2. Common mode current suppression through certain constructions
3. Impedance conversion through certain constructions (impedance ratio not equal to 1:1)

The most common use of Barron is to connect unbalanced signals into balanced transmission lines for long-distance transmission. Compared to single ended signaling using coaxial cables, differential signaling using balanced transmission lines is less affected by noise and crosstalk, can use lower voltages, and is more cost-effective.
Barron's application areas include: radio and baseband video, radar, transmitters, satellites, telephone networks, wireless network modems/routers, etc.

The Balun provided by Qualwave inc. is an ultra wideband 180 ° signal splitter and combiner which can converts an unbalanced 50 ohm signal into a precisely balanced differential signal. The application fields include optical communication, 112 Gbps PAM4 communication system, high-speed analog-to-digital conversion, frequency response testing of differential devices, and other aspects. It can be bidirectional or differential to single ended, providing excellent amplitude and phase matching in the frequency range of 100 kHz to 110 GHz, while also possessing excellent CMRR and minimal harmonic distortion.

The Insertion Loss range is 6~10.8dB.
The amplitude balance range is ± 1.2dB, and the phase balance range is ± 10dB.
The maximum input power is 1W.
The typical value of group delay is 294 ± 4.0.
