Apple patents wireless transmitter that boosts data speed with dual-phase signals

Apple has been granted a patent for a wireless transmitter design that uses a controller to send data in short bursts. The system splits the signal into two parts with different phases to help the transmitter send information more efficiently. This setup allows the hardware to handle data packets using a specific modulation method known as QPSK.

Why it mattersIt is a standard improvement to how wireless chips send data, which could lead to slightly faster or more reliable connections in future Apple devices.

In the filing’s own words

This disclosure is directed to a transmitter including a phase locked loop (PLL), a modulator, and a power amplifier (PA). A controller including programmable and/or hardened logic circuitry may be coupled to the PLL and the modulator. The controller may provide encoded signals based on quadrature phase shift keying (QPSK) scheme for transmission by the transmitter. In particular, the controller may provide multiple bursts of pulses indicative of data packets to the modulator. Moreover, the controller may provide instructions indicative of generating clock signals with in-phase and quadrature phases to the PLL. The PLL may generate clock signals corresponding to the in-phase and quadrature phases. As such, the transmitter may generate in-phase and quadrature output signals based on receiving each burst of pulses with either in-phase or quadrature phases.

What exactly they claim (claim 1)

1. A wireless transmission circuit comprising: a modulator configured to generate first output data signal using a first clock signal based on a first phase and generate second output data signal using a second clock signal based on a second phase; and a power amplifier coupled to the modulator, the power amplifier configured to generate a first amplified output data signal based on the first output data signal, and generate a second amplified output data signal based on the second output data signal.
