Problems solved by technology

In other words, in the process of receiving or transmitting a signal, the signal will pass through the switch unit 13, which may cause loss of signal strength. Power and performance, while the signal received by the antenna unit 11 is transmitted to the receiving path PATH r1 and PATH r2, the sensitivity of the receiving end will be reduced

Abstract

The invention discloses a radio frequency front-end module which comprises a receiving and transmitting end, a control unit, a first transmitting block and a second transmitting block, wherein the first transmitting block and the second transmitting block are connected with the receiving and transmitting end and the control unit; and the control unit is used for controlling the opening or the closing of the first transmitting block and the second transmitting block, so that the first transmitting block and the second transmitting block can directly transmit signals to the receiving and transmitting end, and loss of the signal intensity caused by the fact that the signals pass through an opening and closing unit is avoided.

Description

technical field [0001] The invention relates to a wireless radio frequency front-end module, wherein the first transmitting block and the second transmitting block directly transmit signals to the receiving and receiving ends, which can avoid the loss of signal strength caused by the signals passing through the switch unit. Background technique [0002] see figure 1 , is a schematic block diagram of an existing wireless radio frequency front-end module. As shown in the figure, the wireless radio frequency front-end module 10 includes an antenna unit 11, a switch unit 13, a first transmitting amplifier 151, a second transmitting amplifier 153, a first impedance unit 171, a second impedance unit 173, a A first receiving circuit 191 and a second receiving circuit 193 . [0003] The switch unit 13 is mainly used as a control switch for transmitting or receiving of the radio frequency front-end module 10. When transmitting a wireless signal with the radio frequency front-end mo...
