A new wideband 3-dB tandem coupler is presented that has wide bandwidth using four 90° short stubs. The proposed tandem coupler does not require a higher transmission line impedance or a narrower coupling gap than conventional couplers. Measuremen...

This paper proposes a new 3-branch-line coupler with harmonic suppression. We achieved harmonic suppression by using 90° short stubs. The proposed 3-branch-line coupler with harmonic suppression has the same circuit size as the conventional circui...

We propose a new activation function and verify its performance in a deep image prior network. The new activation function is RSwish, which is Swish with a random slope for x < 0 assuming that the input value of the activation function is x. In ad...
