Abstract
A front-end circuit of the wireless transceiver is disclosed to reduce the number of the pin count of the chip, and achieve the impedance matching. The circuit comprises an antenna unit, a receiver, and a transmitting block, all of which are connected together, wherein there is no switch provided between the receiver and the antenna unit, such that the loss of switch can be avoided for reducing the noise figure and improve the sensitivity of the receiving path accordingly.
