摘要： An active magnetic antenna with a ferrite core having a winding is provided, forming a frame magnetic antenna which is connected with a low-noise transistor, to amplify a signal of the frame magnetic antenna. A base of the transistor is connected directly to one contact of the winding, and a second contact of the winding is capable of shifting a voltage of the base of the transistor. The impedance of the frame magnetic antenna is adjusted as a complex conjugate with an impedance of the base of the transistor of the low-noise amplifier, and the winding eliminates its own resonances.

摘要： A device and method for controlling the baud rate between a portable telephone and an external device is provided. A first input/output (I/O) port is connected to the portable telephone which transmits and receives data to/from the portable telephone, and a second I/O port is connected to the external device which transmits and receives data to/from the external device. A controller interposed between the first and second I/O ports, detects a first baud rate of the portable telephone, converts an initial baud rate of the first I/O port to the first baud rate, and transmits the data to the portable telephone via the first I/O port. The controller also detects a second baud rate of the external device, converts an initial baud rate of the second I/O port to the second baud rate, and transmits the data to the external device via the second I/O port.
