RF directional couplers are primarily used in radio frequency (RF) signal measurement, such as power measurements, identifying signal levels, and isolation or enabling signal shared paths. RF directional couplers are commonly used on wireless communication systems, aviation systems, radio systems, etc. The model 10616-20 RF directional coupler from Tri Tronics is a versatile and high-performance device designed for use in wireless applications in the frequency range of 617-3000 MHz.

The10616-20 directional coupler utilizes balanced power dividers to dissipate relative signal energy between two output ports and two input ports. The power dividers use four equal series inductors to divide both incoming and outgoing RF signals with equal signal power ratios. The signal strength at each port is determined by design tolerances and signal amplification. The directional coupler consists of three ports- Input, Output and Coupled (Tap) port. The power dividers are identical and one input arm is connected to the output port, and the other consists of the coupled port. One of the power dividers is connected to the input port, and the other consists of ports connected to the output port.

When an incoming signal is applied at the input port, most of the signal power is dissipated either to the output port or the coupled (tap) port. The ratio of signal power at the tap port to the signal power at the output port is determined by the design tolerance. When the power dividers of the directional coupler are out of balance; signal loss is minimized between the output port and the tap port. Because of this, the 10616-20 directional coupler can transmit a signal with a low power loss that is greater than that of 2 dB.

The 10616-20 directional coupler is also capable of handling higher power levels, which is especially useful when the device is connected to a high power amplifier (HPA). The HPA supplies a high current, which increases the efficiency of the directional coupler by allowing the device to handle higher power levels without compromising any of its other operational features. Furthermore, the use of high power levels allows the directional coupler to be used for testing and monitoring of high-power amplifiers without having to worry about overloading the device. This makes the 10616-20 directional coupler an ideal solution for testing and monitoring HPA’s.

The 10616-20 directional coupler also can be used for automatic gain control (AGC) applications. The AGC can be used to control the signal path from the input port to the output port. Since the power dividers are used to determine the signal strength at each port, the AGC can be used to adjust the signal power ratio that is applied to the output port. This allows the 10616-20 directional coupler to transmit a lower power level from the input port to the output port. Thus, when AGC is enabled, the signal gain of the directional coupler is increased without having to employ additional amplification.

The 10616-20 directional coupler is also suitable for use in radio-frequency (RF) signal measurement applications. The device can be used to measure the level of RF signals, such as identifying the received signal strength (RSS) of signals, and the power level of signals. It can also be used to determine the level of isolation needed between two signal paths. Thus, the directional coupler is also useful for determining the signal quality and channel interference.

The 10616-20 directional coupler is also one of the most efficient ways to share a given signal path. This is accomplished by the device’s ability to redistribute the energy between its two output ports and two input ports. By connecting two input ports to a single output port, the 10616-20 directional coupler can be used to enable signal sharing. This is especially useful in communication networks where data needs to be distributed among multiple nodes.

In conclusion, the 10616-20 RF directional coupler from Tri Tronics is an efficient and versatile device designed for wireless applications in the frequency range of 617-3000 MHz. Its three ports – input, output and coupled or Tap port, combined with two power dividers in the form of series inductors, make it an ideal solution for applications such as power measurements, identifying signal levels, and enabling signal shared paths. Additionally, its ability to handle higher power levels makes it suitable for use with high-power amplifiers.
