RF directional couplers are important components when designing radio frequency (RF) systems. They are used in a variety of applications to make measurements, give protection to receiver circuits, and adjust specific parameters in the system. One such component is the CP0402A1842ALTR. This article will discuss its application field and working principle.

The CP0402A1842ALTR is designed for high power, high linearity, and high isolation applications in the 400-2000 MHz frequency range. Typical applications include cellular base station power amplifiers, repeater amplifiers, transmitter front ends, and broadband amplifier circuits. The directionality of the coupler is excellent, with a coupling ratio as low as 0.5 dB. It is perfect for any application that require accurate coupling over a wide frequency range.

The CP0402A1842ALTR is a directional coupler with a symmetrical type of construction. It is built with four spiral coupled lines, two radiating elements and two coupling lines. It is then packaged into an SMT package measuring only 0.4x0.2x0.2mm. This component offers excellent high isolation with excellent input and output return loss. It also has excellent linearity, making it the ideal directional coupler for high power applications.

The working principle of the CP0402A1842Altr is simple. The primary input is connected to the two opposing radiating elements. The coupling lines are driven by the incoming RF signal. The voltages from each coupling line are then combined and routed to the two opposing radiating elements. The coupling signals are then combined and routed out of the back of the component. The result is an isolation of up to 34dB.

The CP0402A1842Altr is a versatile component. It can be used in a wide variety of applications, including in repeater amplifiers, power amplifiers, and broadband amplifier circuits. It can be used in combination with other directional couplers to provide protection for a system’s receiver circuits, while still allowing perfect signal coupling over a wide frequency range. In addition, it can be used to adjust specific parameters in an RF system, such as antenna pattern and frequency.

The CP0402A1842Altr is a high quality, low power, directional coupler. It is designed to work in the 400-2000MHz frequency range and offers excellent isolation as well as excellent input and output return loss. Its symmetrical construction offers excellent directionality, with a coupling ratio as low as 0.5 dB. It is perfect for any application that requires accurate coupling over a wide frequency range.
