Introduction:

A RF Power Divider or Splitter, also known as a directional coupler or hybrid coupler, is a device used to split an incoming signal on a transmission line into two or more parts. The PWD-5526-04-SMA-79 is a four-way power divider/splitter, measuring 2.8 x 5.2 inches, which can handle signals in the range of DC to 6 GHz. It has an insertion loss of 0.8 dB and a return loss of 22 dB.

Application Field:

The PWD-5526-04-SMA-79 is a versatile device, suitable for use in a variety of applications. It is ideal for dividing or combining power in multi-transmitter systems, wireless base stations, land-mobile radio systems, and antenna arrays. It can also be used for distributing clock signals, amplifying signals, and switching multiple antennas. Additionally, the device can be used to detect interference in a wireless communications network as well as for testing and monitoring signals.

Working Principle:

The PWD-5526-04-SMA-79 operates on a principle known as hybrid coupling. It consists of two independent port pairs, labeled “A” and “B”. The output of port “A” consists of two signals, one of which is a sum signal that is the same amplitude but in opposite phase as the input signal. The second signal is the difference signal, which is the same amplitude but in the same phase as the input signal.

At port “B”, the signals are split equally between two ports, each with equal amplitude and 180 degrees out of phase. The sum signal is the input signal plus the difference signal, while the difference signal is the input signal minus the difference signal. By ensuring the signals at port “B” are exactly equal and 180-degrees out-of-phase, the RMS output of port “B” and the other three ports are minimized.

The PWD-5526-04-SMA-79 also incorporates a robust protection circuit designed to prevent damage to the device from excessive input signal power. When the circuit senses an overload condition, it automatically reduces the input power by a predetermined amount until the overload is removed.

Conclusion:

The PWD-5526-04-SMA-79 is a four-way power divider/splitter designed for use in a variety of applications ranging from multi-transmitter systems to interference detection. It operates on a principle known as hybrid coupling and has a built-in protection circuit to prevent damage from excessive input signals. This device is easy to install and can handle signals from DC to 6 GHz with low insertion loss and high return loss.
