1R0260-3

RF Directional Couplers are components which are used to couple, or transfer a portion of the energy of a signal from one circuit to another. The 1R0260-3 is a RF directional coupler used for coupling and sensing RF signals in the frequency band of 1.7 GHz to 2.7 GHz. It has a coupling value of 26 dB, which corresponds to a power transfer of approximately 39%. It also has an insertion loss of 1.25 dB and isolates the source path from the load with a return loss of greater than 15 dB. The 1R0260-3 is designed to meet high-frequency requirements, such as in wireless base stations and cellular systems.

The working principle of the 1R0260-3 directional coupler is based on the principle of waveguide splitting. A waveguide passage along with two perpendicular slots is used to form a directional coupler. The center of the coupler is the point at which the slots form a cross. This is where the two signals flow – one from the source to the load, and the other from the load to the source. At this point, the waveguide walls impart an inductive effect to the signal. This leads to a small degree of coupling between the two signals, which is then amplified by the directional coupler.

The 1R0260-3 directional coupler is used in applications where signals have to be received from a source without disturbing or changing the source power level. This is used to measure the power levels of an RF signal without interfering with it. It is also useful in systems that require the transmission of signals over a large distance, as it can transmit a signal with a small amount of power and still maintain high signal integrity. The 1R0260-3 is often used in base stations, transmitters, and communication systems to monitor the power levels of the signals.

The 1R0260-3 directional coupler can be used in a wide variety of applications, due to its high frequency range, high coupling value, and low insertion loss. It has been widely used in base stations, transmitters, cellular systems, and communication systems. It can also be used to measure the output power levels of RF signals such as GPS, WIFI, and Bluetooth.

The 1R0260-3 directional coupler is a reliable and versatile component for many applications. It provides a high degree of coupling and isolation, and can be used to transmit and receive signals with high signal integrity. It is also designed to meet high frequency requirements, making it suitable for a wide range of applications. The 1R0260-3 is an ideal component for any system needing to transmit or receive high frequency signals.
