Abstract: An IC device (100) includes an IC body (106) having a base layer (108) and first and second upper layers (114, 116) on the base layer. The IC body includes a cavity region (104) extending through said base and first upper layers and at least a portion of said second upper layer. In the IC device, a portion of said second upper layer in the cavity region comprises a planar inductive element (102) having first and second contacting ends (140, 142). In the IC device, at least one support member (128, 130, 132) extends at least partially into said cavity region from said IC body in at least a first direction parallel to said base layer and intersects at least a portion of said planar inductive element.

Abstract: Baseband processor and communication overloading can be relieved in a portable wireless communication terminal by decentralizing power control (38, 39) and frequency shift control (75) functions that are conventionally concentrated in the baseband processor. A timing sequencer (31) for power control can be integrated into a transceiver of the portable wireless communications terminal, thereby advantageously permitting power control signals to be generated on the transceiver side (27, 29) rather than the baseband processor side. Shadow registers (74) containing information indicative of commonly used or repeated frequencies can be integrated into the transceiver side, thereby advantageously relieving the baseband processor of corresponding frequency shift control responsibilities.

Abstract: A digital signal processor generates in-phase, quadrature-phase and amplitude signals from a baseband signal. A modulator modulates the in-phase and quadrature-phase signals to produce a modulated signal. A phase locked loop is responsive to the modulated signal. The phase locked loop includes a controlled oscillator having a controlled oscillator input. An amplifier includes a signal input, amplitude control input and an output. The signal input is responsive to the controlled oscillator output and the amplitude control input is responsive to the amplitude signal. The in-phase and quadrature-phase signals may be normalized in-phase and quadrature-phase signals. Alternatively, a phase tracking subsystem may be provided that is responsive to the quadrature modulator to produce a phase signal that is responsive to phase changes in the modulated signal and that is independent of amplitude changes in the modulated signal.

Abstract: An RF amplifier for a transmitter develops a phase modulation command representing a desired phase modulation of an RF signal, and an amplitude modulation command representing a desired amplitude modulation of the RF signal. An oscillator develops an RF input signal phase modulated based on the phase modulation command. A power amplifier receives the RF input signal and amplifies the RF input signal based on the amplitude modulation command to develop an RF output signal. A modulation control is operatively associated with the oscillator. The modulation control includes a phase memory for storing phase correction information correlating the amplitude modulation commands to a phase modulation error and a phase control for varying the phase modulation command based on the phase modulation error to correct for unintended phase errors created by amplitude modulation of the power amplifier.

The amplifier control includes a memory for storing correction information correlating desired amplitude of the RF output signal relative to actual amplifier amplitude, and a control varies power amplifier supply voltage responsive to the correction information to linearize amplitude modulation in the power amplifier.

Abstract: A dual band mobile station including a main channel synthesizer and an offset synthesizer for generating the transmit frequency and the receive intermediate frequency (IF) required for operation in each of two different bands characterized by different transmit-receive channel offsets. According to the present invention, the main channel synthesizer does not have to change its frequency when the mobile station switches between transmission and reception in either of the two bands so long as a common IF is selected for both bands, which is equal to one or the other of the channel offsets. This IF selection also allows for a reduction in the tuning range of the main channel synthesizer.

Abstract: According to a second embodiment of the invention, a mobile phone receiver comprises a first down converter using a first local oscillator frequency which can be tuned in frequency steps by a programmable digital frequency synthesizer PLL which is locked to a reference frequency. The first down converter converts received signals to a first IF for filtering. A second down converter using a second local oscillator converts first IF signals to a second IF. The second local oscillator frequency is generated using a second digital frequency synthesizer PLL which locks the second oscillator to the reference frequency. A third down converter mixes the transmit frequency with the first local oscillator frequency to produce a lock frequency. A third digital frequency synthesizer PLL compares the lock frequency and the reference frequency to control generation of the transmit frequency.
