| A wireless radio frequency transceiver system for Internet of Things includes: a wireless radio frequency transmission module and a wireless radio frequency receiving module. The wireless radio frequency transmission module is used to shape signal waveform of digital signals from the Internet of Things to modulate the digital signals to form modulated output signals, and adopt a self-mixing technique to increase voltage/current amplitude of the modulated output signals and reduce phase noise. The wireless radio frequency transmission module is further used to adopt a current reuse technique to amplify the voltage/current amplitude of the modulated output signals, and transmit the amplified modulated output signals through a first antenna to a wireless channel. The wireless radio frequency receiving module is used to detect carrier input signals received from a second antenna to obtain baseband signals and demodulate the baseband signals to form differential signals. The wireless radio frequency receiving module is further used to amplify voltage/current amplitude of the demodulated differential signals several times in an open loop state to produce digital output signals, and transmit the digital output signals to a back-end signal processor. | ||||||
| 51 | ADVANCED RF INPUT PORT AGAINST SURGE | US15719538 | 2017-09-28 | US20180102748A1 | 2018-04-12 | Shi Man LI |
| A bi-directional RF signal amplifier includes a RF input port and surge suppression circuitry downstream of the RF input port. First and second communications paths lead from the surge suppression circuitry to first and second RF output ports. The second communications path is considered non-interruptible and can support both downstream and upstream RF communications even in the absence of power being supplied to the RF signal amplifier. The surge suppression circuitry includes a data line connected to the RF input port. A first circuit path is electrically connected between the data line and ground. A gas discharge tube (GDT), within the first circuit path, acts as an open circuit when a voltage across the GDT is less than a predetermined value and acts as a short circuit when the voltage across the GDT exceeds the predetermined voltage. An electronic device is placed in series with the GDT within the first circuit path. The electronic device enables the second communications path of the RF signal amplifier to remain operable even if the GDT fails to a short circuit state due to a breakdown of the gases within the GDT. | ||||||
