Abstract:
1. A wireless communication transmitting and receiving system, comprising: a wireless transmitting and receiving unit, a receiving processing circuit, a transmitting processing circuit, a receiving aerial and a transmitting aerial, wherein both the receiving processing circuit and the transmitting processing circuit are connected to the wireless transmitting and receiving unit, and wherein the receiving aerial and the transmitting aerial are separated by at least 10 dB; the receiving aerial is connected to the receiving processing circuit; the transmitting aerial is connected to the transmitting processing circuit; the receiving processing circuit comprises a receiving surface acoustic filter and a receiver single-pole five-throw switch, wherein the receiver single-pole five-throw switch is connected to the receiving aerial, and a received signal is transmitted to the receiver single-pole five-throw switch; the transmitting processing circuit comprises a transmitting surface acoustic filter, a power amplifier, a low-pass filter, a transmitter single-pole five-throw switch and a broadband coupler, wherein the transmitting surface acoustic filter is connected to the wireless transmitting and receiving unit, and wherein an insertion loss of the transmitting surface acoustic filter is less than 2 dB, a signal is output to the power amplifier for amplification, the signal is output to the low-pass filter for filtering, the signal is output to the transmitter single-pole five-throw switch, and the signal is output to the transmitting aerial via the broadband coupler.
