High frequency circuit, high frequency circuit component, and communication apparatus
The present invention provides a high frequency circuit, a high frequency circuit component, and a communication apparatus that uses the same, the circuit capable of being used for different communication systems, having a high receiving sensitivity and restraining the loss of transmission power. A high frequency circuit of the present invention includes: a first antenna terminal (ANT1) and a second antenna terminal (ANT2); and at least a transmitting terminal (Tx) and a first and a second receiving terminal (Rx1, Rx2) for a first communication system. With each switch, the first and the second receiving terminals (Rx1, Rx2) can be each simultaneously connected to the first and the second antenna terminals (ANT1, ANT2). Also, the transmitting terminal (Tx) is selectively connectable to either of the first and second antenna terminals (ANT1, ANT2).
