Abstract: Peak maximum current control for a wireless communication device. One example provides a radio including a radio frequency power amplifier (RFPA) and a current measuring circuit configured to sense a current provided to the RFPA. A comparator is connected to the current measuring circuit. The comparator is configured to compare a value indicative of the current provided to the RFPA to a threshold and provide an output indicative of the comparison. The radio includes a switching circuit configured to receive the output from the comparator and generate an amount of attenuation based on the output. A Cartesian feedback loop is configured to receive the amount of attenuation and control the output of the RFPA.

Abstract: An improved antenna configuration for a communication device is provided that enables ultra wideband operation. The antenna may be formed of two sections, a primary section built into the communication device and a replaceable secondary section disposed on a data card. The primary section is common for all frequency bands of operation which the antenna is intended to cover. The replaceable secondary section is unique to predetermined frequency bands and provides tuning for the overall antenna. A data card tray antenna configuration is also provided which is suitable for a stand-alone antenna or as part of a sectional antenna.

Abstract: A vehicle adapter configured to be mounted to a vehicle. The vehicle adapter includes a body sized and shaped to receive and hold a portable communications device, the body including a surface configured to press against the portable communications device. The vehicle adapter further includes a cooling system coupled to the body, the cooling system including a conduit configured to deliver a coolant to an internal channel of the portable communications device. The conduit defines a projection sized and shaped to press against and open a valve on the portable communications device when the portable communications device is received into the vehicle adapter.

Abstract: A method and apparatus for board-to-board circuit connection. In one example, a connector system includes a printed circuit board having a first set of electrical pads and at least one electrical component positioned between the first set of electrical pads and an adapter frame. The adapter frame includes a second set of electrical pads on a bottom surface and connected to the first set of electrical pads of the printed circuit board and a third set of electrical pads on a top surface and electrically connected to the second set of electrical pads. The adapter frame further includes a chamber configured to house the at least one electrical component and having electrical shielding that forms at least a partial Faraday cage around the at least one electrical component. A connector receptacle having a set of pins is connected to the third set of electrical pads.
