Introduction

RF Directional Couplers are components used in radiofrequency systems, allowing an interaction between two circuits without the direct connection of the circuits. It meets the need for balancing signals between devices, measuring power or signal levels, and delivering signals in a certain direction in acoustic systems. While existing couplers are available for a variety of frequency ranges and levels, CP0603A1960HLTR is a much needed coupler with a wide range of applications.

Application Field

CP0603A1960HLTR directional coupler operates in a wide range of frequencies and power levels. The frequency range is from 10 Hz to 6GHz, and the coupling factor all range from 6dB to 40dB. It is ideal for low-noise amplifiers (LNAs) in wireless communication systems and preselection switches in mobile handsets. It is also used in grounding systems to balance signals without electrical contact, in order to improve the phase stability. But more than just RF systems, its wide range of applications can be found in low voltage systems, audio amplifiers, and experiments in production testing, among others.

Working Principle

The CP0603A1960HLTR directional coupler works by separating the main power path from the auxiliary. Separate paths are created to form two paths connected by a magnetic-induction-based mutual-inductance-coupling loop. The separation of these paths allows the control of the main power path and insertion of secondary systems and devices without direct contact between them. The main power path is where the input signal passes, and the auxiliary path is where the devices are connected to provide the interaction. The CP0603A1960HLTR directional coupler can support up to 0.6GHz with high performance and small package size. Along with high coupling values, the directional coupler features low leakage and superior insertion loss. Its two-resonant-mode structure features very low-impedance noise and enables great linearity and low distortion. The high ambient temperature tolerance and extremely low parasitic capacitance make it perfect for high-frequency repeaters, selective exit repeaters, cellular phones, base-station transceivers and satellite communication systems.

Conclusion

CP0603A1960HLTR directional coupler is a reliable component that enables the interaction between two circuits without direct contact, allowing measurements, balancing signals and delivering signals at specific directions in acoustic systems. With its wide range of frequencies and power levels, the directional coupler finds applications in RF systems, audio amplifiers, and low voltage systems, among others. Its two-resonant-mode structure makes it suitable for devices with high-frequency repeaters, selective exit repeaters, base-station transceivers, and satellite communication systems, while its features such as high ambient temperature tolerance and extremely low parasitic capacitance make it an unbeatable solution.
