HIGH FREQUENCY CIRCUIT AND COMMUNICATION DEVICE

PROBLEM TO BE SOLVED: To inhibit a distortion signal of a low frequency side transmission signal from dominating over a high frequency side reception signal.SOLUTION: A high frequency circuit comprises: a plurality of first duplexers 10L1 each including a first transmission filter 12L1 having a first transmission band, a first reception filter 14L1 having a first reception band, and a first common terminal 18L1 having one end of the first transmission filter connected with one end of the first reception filter; a first switch 20L for selecting any one of such first common terminals to be connected to a first antenna; an LPF or BPF 32 connected between the antenna and the first switch to pass signals in such first transmission bands and such first reception bands; and a second duplexer 10H1 including a second transmission filter 12H1 having a second transmission band higher in frequency than such first transmission bands, a second reception filter 14H1 having a second reception band higher in frequency than such first reception bands, and a second common terminal 18H1 having one end of the second transmission filter connected with one end of the second reception filter, the second common terminal 18H1 connected with a second antenna.
