Abstract

In a manufacturing environment data has been collected on the changes in performance of fused biconic couplers due to temperature cycling and due to long term high temperature storage. The average change in insertion loss after 20 temperature cycles from -40 degree(s)C to +75 degree(s)C for a 50% 1X2 coupler is 0.03 +/- 0.025 dB with a standard deviation of 0.1 dB. The average change in excess loss is 0.03 +/- 0.02 dB. Continuous monitoring of coupling ratio while temperature cycling from -40 degree(s)C to +75 degree(s)C showed a variation in coupling ratio of less than 0.5% at the extremes compared to 25 degree(s)C.
