1G0619-20

RF Directional Coupler

1G0619-20 is a RF directional coupler designed for a wide band signal strength testing in communication engineering and microwave engineering. It operates in the frequency range of 1GHz to 6GHz with excellent directivity to allow for high-precision software calibration.

The direction coupler consists of four main elements: the RF Input port, the RF Output port, the Coupling port, and the Isolation port. The RF Input port is used to connect to the source of the radio frequency signal. The Coupling Port and the Isolation Port are connected together and used to measure the directivity in the given frequency range. The radio input signal will go through from input port to the coupling port, while the signal from the isolation port is blocked and used for measurement. The RF Output port is also connected to the coupling port as the output of the RF signal.

The working principle of 1G0619-20 relies on the power transfer between different ports. The total power of the input signal is partitioned between the output port and the coupling port by the Coupler. The power in the coupling port will be coupled to the load, while the power in the isolation port remains stagnant. This isolation port will measure the signal’s power and can be used to achieve a precise calibration.

The design of 1G0619-20 is based on the theory of different signal strength between the coupling and the isolation ports. In the Frequency domain, the power is isolated, which means that there will be no power transfer from one port to the other. The signal will be stablized and allow for a precise calibration.

1G0619-20 is applicable for various RF signal strength tests in the 1GHz to 6GHz range. It is ideal for field strength testing, antenna measurement and other applications which require a precise calibration. The directional coupler also supports a wide band and will accurately measure the signal strength for a wide variety of frequencies.

Overall, 1G0619-20 is a reliable RF Directional Coupler for testing wide band signal strength. The design is based on the power transfer theory in the frequency domain and allows for a precise calibration to be achieved. With excellent directivity and wide band frequency support, the 1G0619-20 is ideal for various testing in communications engineering and microwave engineering.
