TetraFlex® 7.5 Manual 4-14
4.2.3 BS414 4-way Hybrid Combiner system
The BS414 can optionally be fitted with a 4-way Hybrid Combiner module instead of the
Cavity Combiner. To compensate for the missing filtering in the cavity the TF411 is replaced
with the TF412 60dB TX Filter.
TH414 TF412
The TH414 consists of four dual circulators followed of a 3-dB Wilkinson combining tree
giving a theoretical insertion loss of 6dB.
