Switch circuit, control method, control device, radio frequency switch and readable storage medium

A switch circuit, comprising:

• an antenna port;
• and
• multiple switch branches arranged parallel to each other;
• wherein
• each of the switch branches comprises a first switch, a second switch and a third switch;
• a first end of the antenna port is connected with an antenna;
• a second end of the antenna port is electrically connected with a third end of the first switch of each of the switch branches respectively;
• a fourth end of the first switch of each of the switch branches is electrically connected with a fifth end of the second switch corresponding to each of the switch branches and a sixth end of the third switch corresponding to each of the switch branches respectively;
• a seventh end of the second switch corresponding to each of the switch branches is connected with a ground terminal;
• an eighth end of the third switch corresponding to each of the switch branches is electrically connected with a ninth end of a load corresponding to each of the switch branches;
• a tenth end of the load is connected with the ground terminal;
• the first switch, the second switch and the third switch comprise a plurality of electronic switches;
• and
• a number of electronic switches comprised in the first switch or the second switch is greater than another number of electronic switches comprised in the third switch.
