On the other hand, the construction of the mobile communication base station is more and more difficult due to the constraint of environmental protection problems such as base station radiation, and the seamless coverage of the mobile communication network by the base station equipment is more and more difficult. Under such circumstances, a wireless relay device such as a mobile phone companion is one of the main technical means for solving the above problems. The wireless relay equipment is placed in the coverage edge area of the base station, and the coverage range of the base station can be expanded. The current wireless relay devices are classified into analog wireless relay devices and general digital wireless relay devices. Whether analog wireless relay devices or digital relay devices in general, the structure is implemented by a combination of separate devices or modules. However, a discrete device can only perform a certain function; although the link combined by a plurality of devices realizes the basic function of signal amplification and relay, as the BPF (band-pass filter) used in the link basically adopts a medium or acoustic surface filter, the out-of-band rejection capability of the link is very poor, and once the BPF device is fixed, the out-of-band rejection capability of the system cannot be changed. This makes the wireless relay equipment between different operators amplify the adjacent frequency signals of other operators besides amplifying the own frequency signals. Due to the band-pass performance in the same operator, cell signals cannot be screened, so that multipath interference and intermodulation interference are generated; thereby affecting the service performance and user experience of mobile communications.

In modern society, with the development of mobile communication technology, the rapidly increasing number of mobile communication users poses a great challenge to the capacity of a mobile communication network. On the other hand, the construction of the mobile communication base station is more and more difficult due to the constraint of environmental protection problems such as base station radiation, and the seamless coverage of the mobile communication network by the base station equipment is more and more difficult. Under such circumstances, a wireless relay device such as a mobile phone companion is one of the main technical means for solving the above problems. The existing wireless relay equipment is divided into analog wireless relay equipment and digital wireless relay equipment, and as shown in fig. 1, the analog wireless relay equipment comprises two sets of radio frequency links, one set of radio frequency links is a downlink and the other set of radio frequency links is an uplink; a downlink receives a wireless signal transmitted by a base station through an access antenna, and the wireless signal is amplified and filtered and then sent to a terminal through a covering antenna; an uplink receives a wireless signal transmitted by a terminal through a covering antenna, and the wireless signal is amplified and filtered and then is transmitted to a base station through an access antenna; the specific link comprises the following modules or devices: an access antenna, a cover antenna, a switch (sw (switch), used in a TDD (Time Division duplex) system) or a duplexer (dup (duplex), used in an FDD (Frequency Division duplex) system), a Low Noise Amplifier (LNA), a band-pass filter (BPF), a Voltage controlled Gain Amplifier (VGA), which may also be a combination of a Gain module and an attenuator), an Automatic Level Control device (ALC, Automatic Level Control), and a power Amplifier module (PA).
