A communication terminal is described comprising a modem; a first memory configured to store configuration data for the modem; a second memory configured to store a system boot firmware; and a processor configured to execute the system boot firmware and to read the configuration data from the memory and provide it for the modem under the control of the system boot firmware.

Communication terminal and method for providing configuration data for a modem with system boot firmware

A near field communication (NFC) communicator includes a housing, an NFC controller and an antenna circuit located in the housing. The antenna circuit enable inductive coupling of a near field electromagnetic signal with another antenna circuit in near field range. The antenna circuit includes an antenna element to generate the electromagnetic signal. The communicator also includes a receiver circuit located in the housing for extracting data from modulation induced in the electromagnetic signal which is caused by the inductive coupling of the near field electromagnetic signal with another antenna circuit, a transmitter circuit to generate the near field, a load modulator to modulate the near field to the reader and an energy harvesting circuit to power the rest of the circuit from the external field. A ferrite sheet is located in the housing such that a gap is maintained between the antenna element and the ferrite sheet.

An RF transmitter provides both GSM and EDGE capability by implementing collector voltage control over the power transistor(s) in a power amplifier. During EDGE mode, linear base-biasing a power amplifier (PA) allows collector control to provide either saturated mode PA operation (during ramp up/ramp down) or linear mode PA operation (during data burst). Collector control can therefore be used to provide the accurate ramp up and ramp down profiles required for both GSM and EDGE burst output signals, and can also be used to set the level of the constant envelope data burst of a GSM burst output signal, while linear mode PA operation can provide the non-constant envelope EDGE data burst. A variable gain amplifier is used to adjust the input signal to the power amplifier such that the desired transmission level is achieved.
