Abstract: A circuit is provided for time division duplexing with a frequency hopping technique and has a total of just two frequency synthesizers for the transmission and reception paths and only one up-converter in the transmission path. The UHF synthesizer frequency is additionally subjected to frequency division prior to insertion as a heterodyne frequency of the assigned converter in the transmission and reception paths, which, owing to the shorter transient recovery times, makes it possible to utilize the UHF frequency synthesizers at different frequencies for the transmission and reception slots, respectively. A particular application is in cordless telephones.
