A method and apparatus for setting an internal register of an integrated circuit (IC) via a multiplexed pin which also passes an RF signal is provided. An internal RF signal path couples the pin to an internal terminal for the RF signal, and a register setting signal path couples the pin to an internal register. The internal register may be an address register, such as a USID address register of a MIPI RFFE bus. A capacitor on the RF signal path may block the constant voltage, and a resistor or inductor on the register setting signal path may block the RF signal. The integrated circuit may include an RF section and a controller section, where the controller section may be used to control the RF section. The controller section is responsive to an address associated with the address register.

The present technology provides an apparatus and a method for transmitting data via two or more FM signals in an interference avoiding manner. The apparatus comprises at least two FM transmitters. Each FM transmitter is configured to transmit a FM signal on a particular FM channel characterized by a certain carrier frequency that includes data and optionally one or more corresponding alternative frequencies (AFs). The apparatus further includes at least two receivers for receiving incoming electromagnetic radiation (EMR). At least one of the receivers is configured to receive incoming EMR associated with at least one of the FM channels, and another is configured to receive incoming EMR at least at frequencies outside of the FM channels. The controller is configured to separately control activation and deactivation of the FM transmitters and determine the carrier frequencies and the one or more AFs based upon incoming EMR.

The invention provides an apparatus and a corresponding method for controlling radiation characteristics of a transmitter of a wireless device. The wireless device includes a transmitting portion that includes one or more antennas that are characterized by one or more radiation patterns. The wireless device further comprises a sensor system for determining an orientation of the transmitting portion and a control system that is operatively coupled to the sensor system and configured to control the supply of power to each antenna depending on the orientation of the transmitting portion.

The invention provides an antenna system for wireless communications and in particular to a multiple antenna system for operation in conjunction with a radio frequency (RF) front end for wireless communication. The antenna system comprises one or more antennas configurable for transmission and reception in a first set of configurations and configured for transmission in a second set of configurations. The antenna system further comprises two or more antennas configurable for MIMO-diversity reception for the second set of configurations. The antennas that are configured for MIMO-diversity reception may be tunable, and may have similar characteristics to enhance MIMO reception. Mobile communications terminals utilizing the antenna system, and radio-frequency (RF) front ends for operation in conjunction with the antenna system are also provided. The antenna system may support communications in multiple frequency bands and/or multiple communication standards of operation.

Multiple antenna system for wireless communication

An apparatus and method for providing a broadband antenna is disclosed. For one embodiment of the invention, a molded antenna structure is provided having a gap between electrical components on the printed circuit assembly (PCA) and an overmolding of the antenna structure. One embodiment of the invention substantially reduces the degradation of the antenna performance in wideband modes of operation compared with prior art overmolding schemes. For one embodiment of the invention, the gap between the electrical components and the overmolding is formed by implementing a 'cap' (covering) over the components on the PCA such that they are substantially surrounded by air between the cap and the PCA surface.

Dielectric encapsulating antenna

Methods of and apparatuses for characterizing the power supplying capabilities of host power supplies providing power to wireless modems. According to an exemplary method, an equivalent series resistance of the power supply is determined and compared to a plurality of maximum equivalent series resistance values associated with a corresponding plurality of transmission power classes. Each power class is designated as a permissible power class at which the wireless modem may be configured to transmit, for each maximum equivalent series resistance value that is greater than the equivalent series resistance of the power supply.
