It is also the very simplest divider.
It has large bandwidth if compared to other kinds (gysel or rat race),
and the bandwidth can also be broaded inserting more
λ/4 sections.
In fact just one λ/4 section could make the impedance transformation,
but if the "jump" is big (e.g. in a 10 ports divider/combiner you have to realize
an impedance transformation of 10), your bandwidth will become smaller,
and/or it could be very difficult to realize lines with very high or low
impedance value.
So, the splitter/combiner system should be tailored to your frequency
band (at low frequency a transmission line wilkinson combiner could
become impractical) and also to the dummy load configuration
and arranging, thinking that a wilkinson combiner needs "floating"
dummy loads while gysel, rat race and hybrid needs a grounded load.
Last, i can suggest to use transmission line combiners starting from VHF
up to SHF, at lower frequencies (1MHz 30 MHz) i can suggest the use
of ferrite transformers.
