Tuning data reported on the Datasheets refer to one single Balanced module.
Multi-Channel combination requires specific calculations for the overall Insertion Loss and Return Loss:
The overall insertion loss is the sum of the Insertion Loss of the single module, increased by the sum of the Wideband Insertion Losses of the following modules:
I.L. (Overall) = I.L. (Single Module ) + n x I.L. (Wideband)
The combination of several Balanced modules involves a derating of the overall Return Loss, influenced by the number of combined channels, channel order and assortment, and adjacency.
For basic reference, and in case Channel-Optimized Wideband tuning, the following table is provided:
|No. of Modules
||Overall Return Loss (VSWR)
||26 dB (1.11)
||25 dB (1.14)
||24 dB (1.16)
||23 dB (1.18)
