What is it about?

Power dividers and directional couplers are passive devices used mostly in the field of radio technology. In a power divider, the input signal is transmitted to two output ports with an equal or unequal power level. power dividers have many applications. These include providing a signal sample for measurement or monitoring, feedback, combining feeds to and from antennas, antenna beam forming, providing taps for cable distributed systems such as cable TV, and separating transmitted and received signals on telephone lines. We have designed, simulated and fabricated a very small power divider with high harmonic suppression and high range of applications.

Why is it important?

We have designed a small Gysel power divider with ultra-wide bandwidth, high power handling capability, good 3-dB bandwidth, and suppresses second to ninth harmonics.


It was a pleasure to write this article because it has authors I have worked with for a long time. This article also led me to contact the manufacturers of telecommunications devices and eventually to become more involved in radio frequency circuit research.
