A RF directional couplers are small and compact radio frequency (RF) components effectively designed to narrowband or wideband usage in both transmit and receive applications. The CP0402A0836ANTR is a model of these miniature electrical components that offer performance to match other RF connectors. The CP0402A0836ANTR RF directional coupler provides an accurate transfer of radio signals between two circuits while maintaining isolation of the circuits.

Applications and Functions of CP0402A0836ANTR

RF directional couplers, such as the CP0402A0836ANTR, are widely used in wireless communication systems where high speed data transmission are required, such as WiMax, GSM/EDGE, CDMA, and others. The CP0402A0836ANTR is also appropriate for testing purposes and is specifically designed for highly reliable systems such as military radios, test-bed systems, and wireless communication systems. The wideband performance and extremely low insertion loss of the directional coupler makes it an ideal choice for antenna coupling in radio receivers.

The CP0402A0836ANTR is designed using a microstrip line circuit and a pair of transformers to convert the low impedance signals into higher or lower impedances. This combination of transformers and microstrip line circuit allows the coupling ratio to be accurately matched to the desired values. It features a wide band frequency from 0.1 GHz to 1.0 GHz, and is available with different coupling ratios, depending on the application needs.

Benefits of CP0402A0836ANTR

The CP0402A0836ANTR is an excellent choice for RF test & measurement applications because of its low insertion loss, wide bandwidth, and lowly correlated return loss. It has excellent stability of up to ±1dB over temperature. Its ability to maintain isolation between two circuits allows it to be well suited for unequalized applications where high linearity is required.

The CP0402A0836ANTR also has a wide range of frequency and coupling ratios to offer system designers a wide range of RF test and measurement options. With its very low insertion loss and small package size, it is an ideal choice for applications where space is at a premium. The use of multiple CP0402A0836ANTR directional couplers can provide additional flexibility when testing complex RF systems.

Working Principle of CP0402A0836ANTR

The CP0402A0836ANTR is based on a microstrip line circuit and a pair of transformer cores. The cores, which include a transmitter and a receiver, are designed to match the frequency of the signal to be directed. Two rectangles of differential signal are applied to two inputs of the transformer cores, with one rectangle representing the signal from the transmitter, and the other rectangle representing the signal from the receiver. The coupling ratio of the RF directional coupler is controlled by adjusting the magnetic flux of the transformer cores.

The microstrip line circuit also plays an important role in the performance of the directional coupler by providing shielding between the signal lines and transformer cores. The microstrip line also provides a consistent and predictable RF signal requiring minimal tuning adjustments. By coupling a pair of transformers with a microstrip line circuit, the CP0402A0836ANTR provides a highly accurate transfer of radio signals between two circuits while maintaining isolation between the circuits.

Conclusion

The CP0402A0836ANTR is a miniature RF directional coupler that is designed for test and measurement applications. Its low insertion loss, wide frequency range, high linearity, and small size make it an outstanding choice for many RF applications. It also provides shielding between the signal lines and transformer cores along with a consistent and predictable RF signal requiring minimal tuning.
