ELECTRONIC COMPONENTS & MATERIALS (China), Vol 19, No 3, P 39 40 (Jun 2000) In Chinese The construction of automated laser tuning system and the tuning process are presented with the automated wide band tuning of a five bit L band digital phase shifter as example. The design method for tunable phase shifter and the tuning algorithm are also discussed. The technology of automated laser tuning can be widely used in various microwave circuits for reducing tuning time and production cost, and for meeting the demand for large quality production.(0 refs.)
