Abstract:
There is provided a communications circuit for reducing crosstalk. The communications circuit for reducing crosstalk may include: a conductive power supply pattern supplying driving power applied from the outside; a first transformer implemented as an integrated passive device (IPD) type having a first input conductive line receiving a first signal of a low-frequency band received from a first power amplifier and a first output conductive line close to the first input conductive line and electromagnetically coupled with the first input conductive line, and receiving the driving power supplied from the conductive power supply pattern through a terminal formed on the first input conductive line; and a second transformer implemented as the IPD type having a second input conductive line receiving a second signal of a high-frequency band received from a second power amplifier and a second output conductive line close to the second input conductive line and electromagnetically coupled with the second input conductive line, and receiving the driving power supplied from the conductive power supply pattern through a terminal formed on the second input conductive line, and the conductive power supply pattern may include an inductor component. Therefore, crosstalk between the low-frequency band and the high-frequency band can be reduced.
