RF power dividers, also known as RF splitters, participate in sessions to range and redistribute signals for the spilt or combined signal gain. As discussed in various online forums and user guides, the EHF-FD1503 is an ideal example of RF power divider.

The EHF-FD1503 is a low-loss wide band and wide impedance power divider. It is designed to offer satisfactory signal transfer performance in both wireless communication and common radio frequency base station systems.

With a frequency range of 1.2GHz-2GHz, the EHF-FD1503 offers 15dB of maximum insertion loss for SMA port and its isolation exceeds 25dB. It also has a very low return loss of less than 0.5dB. Furthermore, it also supports a variety of interference rejection, especially in high rejection and low-level splitter applications.

The application fields of the EHF-FD1503 mainly includes:Wireless communication,feeder for radio frequency base station, RF test and smart antenna application. The wireless communication applications include cellular mobile communication systems, VHF military communicators, UHF data radio networks, LTE and 3G data networks, satellite communication links and wireless LANs. The radio frequency base station applications comprise of the signal division system for various radio frequency bands.

The working principle of the EHF-FD1503 is based on the ring structure concept such as that found in common electrical ring structure. The principle is well laid out in online tutorials and user guides showing the processes and components involved in the power divider\'s operation.

The EHF-FD1503 essentially uses the branch signals from both the input ports thus converting them to an amplitude divided and phase opposite output with in-phase combined signals. This is in reference to one single component’s reflectional coefficient, allowing the energy of these signals to be admitted to the output port. The result obtained is a decrease in amplitude of both the signals, hence reducing the power and a transfer of a certain phase of each signal as well.

The power divider has a transmission line network consisting of resistive loads, inductors, capacitors, and voltage dividing elements. With a combination of these components, the EHF-FD1503 is able to split the input power between the output branches thereby easily controlling the gains of all the transmitter ports. As a result, the divider can achieve an excellent power distribution and low insertion loss performances even in the high frequency range.

The complete assembly incorporated in the EHF-FD1503 is also capable of reversing phase and amplitude of the signal while maintaining a low insertion loss and narrow band return loss. Ultimately, the purposes of the EHF-FD1503 are accomplished through efficient signal distribution, high Isolation and very low return loss.

In conclusion, RF power dividers have many application fields and various working principles of which include the EHF-FD1503 that offers good signal transfer action in both wireless communication and common radio frequency base station systems with low insertion losses and a broad frequency range of 1.2GHz-2GHz.
