Splitter and electronic device

An electronic device, comprising:

• a signal source;
• and
• a splitter, having a common port, a first port, and a second port, wherein the common port is coupled to the signal source, and the splitter comprises:
• a common transmission line, coupled between the common port and a common node;
• a first transmission line, coupled between the first port and a first node;
• a second transmission line, coupled between the second port and a second node;
• a third transmission line, coupled between the common node and the first node;
• a fourth transmission line, coupled between the common node and the second node;
• a resistor, coupled between the first node and the second node;
• and
• a first reactance circuit, coupled between the first node and the second node, wherein the first reactance circuit comprises a first inductor and a first capacitor coupled in series, but the first reactance circuit does not comprise any resistor;
• wherein the splitter operates at a central frequency, and the first reactance circuit is configured to reduce isolation between the first port and the second port at the central frequency.
