Radio frequency circuit

A radio frequency (RF) circuit applied to reduce signal interference, the RF circuit comprising:

• a first microchip for transmitting RF signal;
• a second microchip for receiving and transmitting RF signal;
• a first signal line, having opposite first and second;
• a second signal line, each of the first signal line and the second signal line having opposite first and second ends, and each first end of each of the first signal line and the second signal electrically connected to the first microchip, and each second end of each of the first signal line and the second signal electrically connected to the second microchip;
• and
• two resistors, wherein each of the first signal line and the second defines first and second gaps, the first gaps adjacent to the first microchip and the second gaps adjacent to the second microchip, when the two resistors are located at the first and second gaps of the first signal line, the first microchip and the second microchip are electrically connected through the first signal line and the resistors and form a connection path to transfer one type of RF signal;
• when the two resistors are located at the first and second gaps of the second signal line, the first microchip and the second microchip is electrically connected via the second signal line and the resistors and form another connection path to transfer another type of RF signal.
