International Classification:

H03C 3/06

US Classification:

332127, 332103, 332128, 331 23, 331 34

Abstract:

A direct division modulator is provided. The direct division modulator includes a symbol mapper converting the input data from a binary bitstream to a desired frequency deviation, such as where the frequency deviation data encodes the information from the bitstream. A converter generates a divide value using the desired frequency deviation information, and a summer adds an average value to the divide value. A converter quantizes the divide value and shapes quantization noise associated with the quantized divide value. A divider modulates a reference signal with the quantized divide value and generates an output signal.

Appl. No.:

15/253269

Inventors:

Ming Yu Lin - Tustin CA, US
Qiang Li - Irvine CA, US

International Classification:

H04W 52/02

Abstract:

A device is disclosed. The device includes one or more memories and one or more processors coupled to the one or more memories. The one or more processors are configured to cause, after a first amount of time elapses from entering a sleep mode of the device, exiting the sleep mode of the device. The one or more processors are further configured to cause receiving a first packet from a network device subsequent to exiting the sleep mode. The one or more processors are further configured to cause, in response to receiving the first packet, transmitting a second packet to the network device. The one or more processors are further configured to cause entering the sleep mode of the device subsequent to transmitting the second packet.

International Classification:

H04B 1/403
H04B 1/3805
H04B 1/408

Abstract:

A wireless transceiver system is disclosed. The system includes a narrow band transmitter. The narrow band transmitter includes at least a delta sigma phased locked loop (delta-sigma PLL) circuit and a non-linear low-power amplifier, where an output of the delta-sigma PLL is coupled to an input of the non-linear low-power amplifier. The system further includes a wide band transmitter. The wide band transmitter includes at least a digital to analog converter (DAC), a low pass filter, a local oscillator mixer and a linear high power amplifier, where an output of the DAC is coupled to an input of the low pass filter and an output of the low pass filter is coupled to an input of the local oscillator mixer and wherein an output of the local oscillator mixer is coupled to an input of the linear high power amplifier.

International Classification:

H04B 5/00

US Classification:

455 411

Abstract:

A communication device includes a first and second near-field wireless (NFW) module operating with a first and second protocol, respectively. A module and method to improve the operational efficiency of the first and second NFW modules are disclosed. Due to close proximity between the first and second NFW modules in the communication device, an undesirable parasitic inductive coupling can occur that can degrade the operational performance of the modules. The first NFW module can be configured to control inductive coupling of the second NFW module when an electromagnetic (EM) field operating with the first protocol is detected. Additionally, the second NFW module can be configured to control inductive coupling of the first NFW module when an EM field operating with the second protocol is detected. Controlling the inductive coupling of each module can be performed by means of detuning an inductive coupling element of each module.
