Abstract
Certain aspects of the present disclosure relate to methods and apparatus for wireless communication. In certain aspects, the apparatus generally includes a first interface configured to obtain, from a baseband module, a multiplexed signal comprising a control signal, a second interface configured to obtain a power signal, a radio frequency (RF) module, a regulator coupled to the second interface and configured to receive the power signal, and a circuit configured to provide the control signal to the regulator. In certain aspects, the regulator, in response to the control signal, may be configured to generate a supply voltage signal by regulating the power signal and provide the supply voltage signal to the RF module.
Claims8
An apparatus for wireless communication, comprising:
- a circuit board;
- a first interface configured to obtain, from a baseband module, a multiplexed signal comprising a control signal;
- a second interface configured to obtain a power signal, wherein the first interface and the second interface are different interfaces on the circuit board;
- a radio frequency (RF) module on the circuit board;
- a regulator on the circuit board and coupled to the second interface and configured to receive the power signal from the second interface, wherein the regulator comprises a power terminal configured to obtain the power signal and an enable terminal configured to obtain the control signal;
- a circuit on the circuit board and configured to provide the control signal to the regulator, wherein the regulator, in response to the control signal, is configured to generate a supply voltage signal by regulating the power signal and provide the supply voltage signal to the RF module;
- and
- a jumper on the circuit board and disposed between the power terminal of the regulator and the enable terminal of the regulator.
A wireless node, comprising:
- at least one antenna;
- a circuit board;
- a first interface configured to obtain, from a baseband module, a multiplexed signal comprising a control signal;
- a second interface configured to obtain a power signal, wherein the first interface and the second interface are different interfaces on the circuit board;
- a radio frequency (RF) module on the circuit board;
- a regulator on the circuit board and coupled to the second interface and configured to receive the power signal from the second interface, wherein the regulator comprises a power terminal configured to obtain the power signal and an enable terminal configured to obtain the control signal;
- a circuit on the circuit board and configured to provide the control signal to the regulator, wherein the regulator, in response to the control signal, is configured to generate a supply voltage signal by regulating the power signal and provide the supply voltage signal to the RF module, wherein the RF module is configured to output for transmission RF signals via the at least one antenna;
- and
- a jumper on the circuit board and disposed between the power terminal of the regulator and the enable terminal of the regulator.
