Circuit with reduced insertion loss

摘要

An electrical circuit has at least two parallel signal paths connected to one another on the antenna side and for which a band reject filter corresponding to the transmission range is implemented in a second signal path for frequency-selective improvement of insertion loss in the transmission range of a first signal path. With a band reject filter, the signal is reflected to the junction of the parallel signal paths arising from the second signal path and thus is rerouted to the first signal path.
