Abstract
Balun circuit which is configured in an on-chip design, and multi-port antenna switch circuit comprising such a balun circuit. The balun circuit has a transceiver loop (), as well as a first antenna loop () and at least one further antenna loop (). The first antenna loop (), the at least one further antenna loop (), and the transceiver loop () are coaxially positioned in one layer of the on-chip design. The multi-port antenna switch circuit further has a first switch (T) connected between a ground terminal (AGND) of the first antenna loop () and a first antenna external connection pad (Pg), and a second switch (T) connected between a ground terminal (AGND) of the at least one further antenna loop () and at least one further antenna external connection pad (Pg).
