TY-300P產品概述
Designed for use where several telephones are connected to a single incoming-outgoing line. The TY Series is adaptable for hybrid, bridging or coupling applications. These coupling transformers provide a correct means of impedance matching and balancing through close coupling and isolation — all parameters must be considered so that existing lines are not degraded. Frequency Response: 300-3,500 Hz ±0.5 dB. Longitudinal Balance: 45 dB min. Return Loss: 26 dB min. Distortion: 0.5% max. Impedance Matching: ±10% over the frequency range. Power Level: –45 dBm to +7 dBm. Complies with FCC Rules Part 68.
