GPS Filters

摘要

DLI has introduced a family of GPS components that includes two bandpass filters, two diplexers and a notch filter. The bandpass filters and diplexer pass both LI and L2 frequency bands. The notch filter attenuates the LI frequency band. Two different versions of the diplexer have been designed and manufactured. The first version has higher insertion loss, but better rejection due to a narrow bandwidth. The bandwidth was widened on the second version to reduce the insertion loss at the cost of eroding the rejection skirts.
