Description

FIELD The present disclosure relates to a hearing device comprising a module. BACKGROUND Nowadays, hearing devices are typically connected to a smartphone in a wireless manner e.g. via a Bluetooth connection. Such wireless connection between the hearing device and the smartphone allows the user e.g. to stream music from the smartphone to the hearing device or to have a voice communication between the hearing device and the smartphone. However, the user may experience a weak signal link e.g. when the user places the smartphone in a bag, a back pocket or a front pocket. In such cases, it may e.g. not be possible to stream music from the smartphone to the hearing device or to make a phone call. Hence, the user may need to take out the smartphone from the bag, the back pocket or the front pocket and to restart an application or the connection. Therefore, there is still a need for an improved hearing device that addresses the abovementioned problems. US 2007/149237 A1 discloses a method of controlling power level of transmit signals from a wireless communication device that is communicating with a plurality of wireless ad-hoc network nodes as part of an ad-hoc network, a value of a usage parameter of a communication between the wireless device and a first wireless ad-hoc network node of the plurality of nodes is detected. A power level of a transmit signal from the wireless device to the first wireless ad-hoc network node is set to a level corresponding to the value of the usage parameter. A device for adjusting a power level in a wireless device includes a parameter detection circuit, that detects a parameter indicative of a relationship between the wireless device and a wireless ad-hoc network node, and a power selection circuit that sets a transmit signal power level from the wireless device to a level corresponding to the parameter detected by the parameter detection circuit. US 2014/002187 A1 discloses systems and methods for integrating functional components of front-end modules for wireless radios. Front-end modules disclosed may be dual-band front-end modules for use in 802.11ac-compliant devices. In certain embodiments, integration of front-end module components on a single die is achieved by implementing a high-resistivity layer or substrate directly underneath, adjacent to, and/or supporting SiGe BiCMOS technology elements. EP 1826914 A1 discloses a high-frequency circuit comprising a high-frequency switch circuit for switching the three-way connection of an antenna to a transmitting circuit for the first communications system, a receiving circuit for a first communications system, and a transmitting/receiving circuit for a second communications system; a first bandpass filter disposed between the antenna and the high-frequency switch circuit; and a balanced-unbalanced conversion circuit disposed between the receiving circuit of the first communications system and the high-frequency switch circuit. CN 111711466 A discloses a three-channel UWB radio frequency front-end module, and the module comprises a low noise amplifier of a receiving channel (RX), a power amplifier of a transmitting channel (TX), a bypass channel capable of being selected as a transmitting/receiving channel according to actual requirements, a high-speed radio frequency selector switch and a control circuit. According to the invention, the miniaturization can be realized by fully integrating the receiving low-noise amplifier and the transmitting low-noise amplifier on the chip; the bypass channel is introduced to increase the dynamic range of a system receiving channel; it is ensured that the low-noise amplifier (power amplifier) is in a closed state in a transmitting (receiving) state, and it is ensured that the low-noise amplifier and the power amplifier are both in a closed state during bypass work, so low power consumption can be achieved.
