Embodiment Construction

[0026] In the following description, various embodiments will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. It will be apparent, however, to one skilled in the art that the embodiments may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the described embodiments.

[0027] A two-way wireless communication system includes a transmitter, receiver and antenna. The transmitter and receiver may be integrated on an integrated circuit (Integrated Circuit, IC) chip, and the antenna may be an off-chip component rather than a part of the IC chip. The communication system may include an off-chip T / R switch to control access to the antenna between the transmitter and receiver and to provide electrical isolation between the transmitter and receiver.

[0028] The use of off-chip T / R switches may deg...

Abstract

Devices and methods are provided for performing wireless communication. In some embodiments, a device includes a transformer including a first winding, a second winding, and a third winding. The device also includes a first transmitter circuit coupled to the first winding and a second circuit coupled to the second winding. The third winding is coupled to the antenna. The first transmitter circuitis configured to transmit a first signal to the antenna through a magnetic coupling between the first winding and the third winding. The second circuit is configured to withstand a second signal fromthe first transmitter circuit without damage, wherein the second signal is generated from the first signal by magnetic coupling between the first winding and the second winding. The turns ratio between the first winding and the second winding may be configured to limit the voltage of the second signal to be within a predetermined threshold.

Description

[0001] Priority claims and cross-references to related applications [0002] This patent application claims the benefit and priority of U.S. Nonprovisional Patent Application No. 15 / 798,501, filed October 31, 2017, entitled "System and Method for Two-Way Wireless Communications." technical field [0003] Embodiments herein relate generally to wireless communications, and more particularly, to systems and methods for two-way wireless communications. Background technique [0004] A two-way wireless communication system includes a transmitter, receiver and antenna. A transmitter may receive data carrying certain information, generate an electrical signal based on the data, and transmit the electrical signal to an antenna. The antenna converts the electrical signal received from the transmitter into a wireless signal. Wireless signals can travel a certain distance in the form of radio waves to transmit information. Antennas also receive wireless signals, convert them to elect...
