It is equipped with a unique directional coupler design which provides excellent directivity across the entire frequency range. The CP0402A1880BLTR has a low insertion loss, high isolation, and an accurate coupling over the entire band. The directional coupler design of CP0402A1880BLTR offers enhanced dynamic range compared to other RF components. Additionally, it is also suitable for use in very densely populated circuits, as it offers a small form factor. Furthermore, the CP0402A1880BLTR is highly reliable due to its robust construction and superior quality components.

Working Principle

The CP0402A1880BLTR uses a coupled line technique to create a bidirectional RF coupling device. It works by inducing a small amount of RF power from the signal line, and directing it to a second line (the secondary line) which is connected to the coupler’s output port. The amount of RF power coupled from the signal line depends on the coupling factor of the CP0402A1880BLTR device, as well as the amount of power present in the signal line. The CP0402A1880BLTR has a very wide range of coupling factors, from 10~20 dB for low power applications to 30~40 dB for higher power applications.

The efficiency of the coupler can also be increased through the use of a “tap-off” point. This is a point inside the CP0402A1880BLTR in which the output port is directly connected to the signal line, allowing for lower coupling losses and higher power levels. This tap-off point also helps minimize the reflections back into the signal line which can cause distortion and other issues.

The CP0402A1880BLTR is also capable of performing functions such as gain equalization, phase compensation, and signal filtering. This is due to its unique design which allows for an accurate and stable transfer of energy across the entire frequency range. This makes the CP0402A1880BLTR an excellent choice for use in portable and low power communications systems.

In summary, the CP0402A1880BLTR is an excellent RF directional coupler which is suitable for use in low power and portable communications systems. It offers a low insertion loss, high isolation, and stable dynamic range across the entire frequency range. Additionally, it is also designed for fast setup time, and is highly reliable due to its robust construction and superior quality components.
