Wireless communication circuit with a wideband received signal strength indicator

A wireless communication circuit with a wideband received signal strength indicator, comprising:

• a front end signal processing unit, electrically connected to an antenna, configured to receive and process a wireless signal from the antenna and to output a low frequency analog signal;
• a filter unit, electrically connected to the front end signal processing unit, and configured to receive the low frequency analog signal from the front end signal processing unit and to output a determined band signal;
• a first analog-to-digital converter module, electrically connected to the filter unit, and configured to receive and transform the determined band signal from the filter unit into a first digital signal;
• a first demodulator, electrically connected to the first analog-to-digital converter module and the front end signal processing unit, and configured to receive and demodulate the first digital signal from the first analog-to-digital converter module and to output a first control signal;
• a second analog-to-digital converter module, selectively electrically connected to the front end signal processing unit or the filter unit, and configured to receive the low frequency analog signal from the front end signal processing unit or the determined band signal from the filter unit, and to transform the low frequency analog signal from the front end signal processing unit or the determined band signal from the filter unit into a second digital signal;
• a second demodulator, electrically connected to the second analog-to-digital converter module, the first demodulator and the front end signal processing unit, and configured to receive and demodulate the second digital signal from the second analog-to-digital converter module and to output a second control signal;
• a first switch, electrically connected between the front end signal processing unit and the second analog-to-digital converter module;
• a second switch, electrically connected between the filter unit and the second analog-to-digital converter module;
• a third switch, electrically connected between the second demodulator and the front end signal processing unit;
• a fourth switch, electrically connected between the first demodulator and the front end signal processing unit;
• and
• a controller, electrically connected to the first switch, the second switch, the third switch and the fourth switch, and configured to control a switching configuration of the first switch, the second switch, the third switch and the fourth switch to determine a circuit operation of the wireless communication circuit.
