This paper deals with an unequal power divider with two matching frequencies by using LC-ladder circuits. This circuit that is constructed based on the Wilkinson power divider, consists of 9 elements. This circuit can achieve the same or wider ban...

We designed and evaluated 1×2 and 2×2 optical couplers using multimode interference (MMI) optical waveguides of Ti-diffused LiNbO3. A Mach-Zehnder electrooptic modulator (MZM) designed using those two MMI couplers as an optical power splitter and ...
This paper treats a power divider with three-frequency matching characteristics consisting of 15 elements. A wide relative bandwidth is considered for each band by placing the matching frequencies on the low frequency side close together for dual-...

In this paper, a 180-degree rat-race hybrid which consists of short transmission lines less than quarter wavelength with shunt capacitors at both ends and an ideal phase inverter is described. We show the possibility of realizing a compact and wid...
