CP0402A1810CNTR

RF Directional Couplers are an integral part of many RF systems which employ a power transfer topography. Broadly defined, RF Directional Couplers employ a device called a Coupler to transfer power from one port to another. CP0402A1810CNTR is an RF Directional Coupler that utilizes unique design technology to provide power transfer from a 25-35W rating source.

Application field

The CP0402A1810CNTR has a wide range of applications. It is particularly well-suited for use in low-power RF systems such as those found in cable modem and satellite receiver systems, TV receivers and remote control systems. Its low power rating also makes it appropriate for use in RF amplifiers and portable digital devices. Additionally, the CP0402A1810CNTR is very well suited to measure and monitor the impedance of transmission lines and other RF applications requiring a power transfer topography.

Working Principle

The CP0402A1810CNTR directional coupler consists of two sections: an amplifier section and a coupling section. The amplifier section amplifies the signal from the transmission line and the coupling section is the part which couples power from the amplified signal. The signal is then coupled onto the coupled line and is used to measure the signal impedances of the transmission line. The CP0402A1810CNTR is designed to allow for precise power transfer between the coupled line and the transmission line.

The amplifier section uses an op-amp and a feedback resistor to amplify the signal. The op-amp reduces the voltage and therefore the level of signal noise, while the feedback resistor determines the gain or ability to increase the output voltage. The coupling section uses an inductive winding to transfer power from the transmission line to the coupled line. This inductive winding is designed to maintain the same impedance between the two lines, and thus preventing losses in power transfer.

The CP0402A1810CNTR is designed to operate in an impedance range of 25-35W, with a minimum coupling of 8dB. It is also designed for a wide frequency range of up to 3GHz, allowing it to be used for a variety of different applications. Additionally, the CP0402A1810CNTR is designed to provide excellent impedance matching, meaning it can be used without the need for additional components.

The CP0402A1810CNTR directional coupler is a reliable and robust device, which makes it an ideal solution for low-power RF applications. It is also relatively easy to install and use, making it a good choice for a wide range of applications.
