Radio frequency circuit

A radio frequency circuit comprising:

• a first filter having a passband that includes a downlink band of n256 for 5th Generation New Radio (5G NR) and a downlink band of Band 1 for Long Term Evolution (LTE) or n1 for 5G NR;
• a second filter having a passband that includes the downlink band of n256 for 5G NR and a downlink band of Band 66 for LTE or n66 for 5G NR;
• a third filter having a passband that includes a downlink band of Band 3 for LTE or n3 for 5G NR;
• a fourth filter having a passband that includes a downlink band of Band 2 for LTE or n2 for 5G NR and an uplink band of n256 for 5G NR;
• a fifth filter having a passband that includes the uplink band of n256 for 5G NR and an uplink band of Band 1 for LTE or n1 for 5G NR;
• a sixth filter having a passband that includes an uplink band of Band 3 for LTE or n3 for 5G NR;
• a seventh filter having a passband that includes an uplink band of Band 66 for LTE or n66 for 5G NR;
• an eighth filter having a passband that includes an uplink band of Band 2 for LTE or n2 for 5G NR;
• and
• a first switch that includes a first terminal connected to an antenna connection terminal, a second terminal connected to the first filter, the third filter, the fifth filter, and the sixth filter, and a third terminal connected to the second filter, the fourth filter, the seventh filter, and the eighth filter.

A radio frequency circuit comprising:

• a first filter having a passband that includes a downlink band of a first band and a downlink band of a second band;
• a second filter having a passband that includes the downlink band of the first band and a downlink band of a third band;
• and
• a first switch that includes a first terminal connected to an antenna connection terminal, a second terminal connected to the first filter, and a third terminal connected to the second filter,
• wherein a combination of the first band and the second band is included in a first predefined band combination for simultaneous communication, and a combination of the first band and the third band is included in a second predefined band combination for simultaneous communication, and
• combinations of the first band, the second band, and the third band are three combinations among combinations of n256 for 5G NR, Band 1 for LTE or n1 for 5G NR, Band 66 for LTE or n66 for 5G NR, and Band 4 for LTE.
