1G0618-6

RF directional couplers have a wide variety of applications. They are used in various industries, including medical, military, and commercial applications. 1G0618-6 is a type of RF directional coupler. This article will discuss the application field and working principle of 1G0618-6.

1G0618-6 is a type of broadband directional coupler that is designed to couple RF signals from one port to another, with a typical coupling factor of 20 dB. It is based on the Wilkinson power combiner principle, which utilizes two 180-degree hybrids that are connected in a reverse-scopic fashion. The central microstrip line has a resonant length that determines its impedance, which keeps the reflection on the line low, and guarantees high coupling accuracy.

1G0618-6 is most commonly used in medical and military applications, thanks to its high coupling accuracy and bandwidth. It can be used to couple RF signals for medical imaging and RF communications systems. Its high dynamic range makes it ideal for medical imaging systems, which require high signal to noise ratio (SNR). It can also be used in military communication systems, as the large coupling factor and low insertion loss make it suitable for high-coverage and distance systems.

1G0618-6 has also been used in commercial applications, such as telemetry and remote sensing systems. This type of coupler has a large coupling factor and wide bandwidth, which are ideal for these types of applications. It can also be used in base station antennas for cellular applications, where its wide bandwidth makes it suitable for multi-frequency operations.

The working principle of 1G0618-6 is based on the Wilkinson power combiner. This type of coupler works by combining two signals from different receivers into a single output. The two receivers are connected in a reverse-scopic fashion, using two 180-degree hybrids. These hybrids are designed to have equal impedance in all directions, which allows for maximum power transfer between the two receivers. The central microstrip line has a resonant length, which determines its impedance and keeps the reflections on the line low. This ensures high coupling accuracy and wide bandwidth.

In conclusion, 1G0618-6 is a type of RF directional coupler that is designed for medical, military, and commercial applications. It utilizes the Wilkinson power combiner principle, where two 180-degree hybrids are connected in a reverse-scopic fashion. The central microstrip line has a resonant length that determines its impedance and keeps the reflection on the line low, ensuring high coupling accuracy and wide bandwidth. This type of coupler can be used for medical imaging, RF communications systems, telemetry, and remote sensing systems.
