Radio frequency circuit

A radio frequency circuit comprising:

• a radio frequency signal input terminal;
• a radio frequency signal output terminal;
• a radio frequency signal input-output terminal;
• a power amplifier comprising an input terminal that is electrically connected to the radio frequency signal input terminal;
• a low noise amplifier comprising an output terminal that is electrically connected to the radio frequency signal output terminal;
• a first band pass filter that has a pass band corresponding to an uplink frequency range of Long Term Evolution (LTE) Band 28;
• a second band pass filter that has a pass band corresponding to a downlink frequency range of LTE Band 28;
• a third band pass filter that has a pass band comprising an uplink frequency range of LTE Band 28B and a downlink frequency range of LTE Band 29;
• and
• a switch group comprising a first terminal that electrically connects an output terminal of the power amplifier to a first end of the first band pass filter, a second terminal that electrically connects a second end of the first band pass filter to the radio frequency signal input-output terminal, a third terminal that electrically connects an input terminal of the low noise amplifier to a first end of the second band pass filter, a fourth terminal that electrically connects a second end of the second band pass filter to the radio frequency signal input-output terminal, a fifth terminal that electrically connects the output terminal of the power amplifier to a first end of the third band pass filter, a sixth terminal that electrically connects a second end of the third band pass filter to the radio frequency signal input-output terminal, and a seventh terminal that electrically connects the input terminal of the low noise amplifier to the first end of the third band pass filter.
