Abstract: A method and apparatus for signal power ramp-up in a communication transmission. Payload data is identified (210, 410) for transmission. A power reference signal is determined (220, 420) for transmission prior to the payload data. The power reference signal and the payload data are combined (230, 430) to form a data burst for transmission. The combined data burst is transmitted (240, 450) as, wherein the power reference signal is transmitted prior to the payload data within the data burst. A feedback signal is provided (250, 460) based on the power reference signal portion of the transmitted data burst, and a pre-distortion signal is calibrated (260, 470) based on the feedback signal.

Abstract: A pulsed radar (10) that uses a single sideband pulsed signal for determining a distance to a target. The radar has twice the target resolution of a conventional pulsed radar using the same bandwidth signal. The single sideband pulsed signal within a transmitter (12) may be produced by mixing a base-band pulsed signal with a radio frequency (RF) carrier frequency and then filtering the resultant amplitude modulated signal to suppress either the upper or the lower sideband signal. Because only one sideband is used, the pulse occupies half the bandwidth that it would in a conventional pulsed radar. For a given bandwidth, the single sideband radar, therefore, has twice the target resolution of a conventional pulsed radar system. The single sideband signal's shape must, however, be preserved during amplification to avoid reintroduction of the suppressed sideband, so highly linear power amplifiers (42) must be used to boost the strength of the signal before transmission.

Abstract translation: 脉冲雷达（10），使用单边带脉冲信号来确定到目标​​的距离。 雷达具有使用相同带宽信号的传统脉冲雷达目标分辨率的两倍。 发射机（12）内的单边带脉冲信号可以通过混合具有射频（RF）载波频率的基带脉冲信号，然后对合成的幅度调制信号进行滤波以抑制上边带或下边带信号来产生。 由于只使用一个边带，该脉冲占用了传统脉冲雷达的一半带宽。 因此，对于给定的带宽，单边带雷达具有传统脉冲雷达系统目标分辨率的两倍。 然而，在放大期间必须保留单边带信号的形状以避免抑制边带的重新引入，因此必须使用高线性功率放大器（42）来在传输之前提高信号的强度。

Abstract: A method and apparatus is disclosed for generating short electronic pulses using a modified differential trigger that is partly an analogue sinusoidal voltage and partly a selectable, DC voltage. The differential trigger is applied to a differential base band pulse generator (38, 60) having a NAND gate (14) and AND gate (12). The trigger is applied to both NAND inputs and to one AND input. The NAND output is applied the other AND input. Such a circuit is an OFF state for all input states. However, as the input switches state, the NAND gate delay causes the AND gate (12) to be ON briefly, generating a short pulse. The timing of this pulse can be controlled by varying the constant DC voltage. By using fast switching SiGe CML gates, short pulses with a controllable time off-set can be generated that are suitable for use in automotive radar applications, using only sub-GHz clocks.

Abstract: A high-power, high frequency (1- 100 GHz) power amplifier (18), made using SiGe transistors. A differential common-emitter amplifier section supplies the voltage amplification, allowing the total voltage swing of the amplifier to be twice the breakdown voltage of the individual transistors (T 1 -T 4 ). Current amplification is supplied by a differential common-base amplifier section, connected in cascode with the differential common-emitter amplifier section. Appropriately chosen resonators in the cascode connection resonate out the Miller effect, negative current feed back of the circuit at the amplifier's operational frequency, allowing the amplifier to provide high power output at the operational frequency.
