Transient attenuation of separate loop coupler with cascade connection¶

The multistage connection of the couplers allows you to expand the working band and realize less transient attenuation. Transient attenuation is a part of the power passing into the auxiliary channel of the coupler.

coupler_attenuation¶: Transient attenuation of one coupler from the cascade, measured in decibels.

Symbol:: A_0
Latex:: \(A_{0}\)
Dimension:: dimensionless

cascade_attenuation¶: Transient attenuation of the cascade, measured in decibels.

Symbol:: A
Latex:: \(A\)
Dimension:: dimensionless

coupler_count¶: Number of couplers in the cascade. See positive_number.

Symbol:: N
Latex:: \(N\)
Dimension:: dimensionless

law¶

A_0 = 20 * log(sin(N * asin(10^(A / 20))), 10)

Latex:: \[A_{0} = 20 \log_{10} \left( \sin{\left(N \operatorname{asin}{\left(10^{\frac{A}{20}} \right)} \right)} \right)\]
