摘要： A power feedforward amplifier uses integral cavities to provide RF isolation between subcircuits of the power amplifier. The chassis includes a main chassis body and a lid structure adapted to couple with the chassis body and define the subcircuit cavities. The inner lid includes an amplifier dividing wall and interstage walls adapted to isolate the main and error amplifier subcircuits of the feedforward power amplifier and further to isolate individual components of the subcircuits. In one embodiment, the amplifier subcircuits are mounted on a single circuit board and isolated from each other by the dividing wall. A delay line subcircuit portion is integral with the main chassis body and is coupled beneath the error amplifier subcircuit to contain and electromagnetically shield a delay line filter subcircuit while providing direct connection with the error amplifier.

摘要： An input signal having amplitude information is pre-distorted and converted into two pre-distorted signals without amplitude information. The two pre-distorted signals are separately amplified and then recombined to generate a linearized amplified output signal having amplitude information. The pre-distortion and conversion may be implemented using a pre-distorter and a LINC modulator. Alternatively, the pre-distortion and conversion may be implemented in circuitry that combines the functions of a pre-distorter and a LINC modulator. The amplified, pre-distorted signals are preferably combined using circuitry that provides at least some impedance matching, such as a transformer or a transmission line tee with transmission line stubs.

摘要： Pre-distortion, whose magnitudenulland preferably phasenullare frequency-dependent, is applied to an input signal in order to reduce spurious emissions resulting from subsequent amplification of the signal. In preferred embodiments, the pre-distortion technique of the present invention is implemented in combination with the (frequency-independent) magnitude and phase pre-distortion technique described in U.S. patent application Ser. No. 09/395,490 (nullthe '490 applicationnull), where the frequency-dependent pre-distortion corresponds to amplifier distortion that has a magnitude that is proportional to the frequency offset from the carrier frequency and a phase shift of null90null on either side of the carrier frequency. The frequency-dependent pre-distortion is generated by differentiating waveforms corresponding to pre-distortion parameters with respect to time and then applying the resulting differentiated pre-distortion parameters to the input signal. Depending on the implementation, the waveforms may be differentiated in either the analog or digital domain.
摘要翻译：预失真（其幅度优选相位是频率依赖的）被施加到输入信号，以便减少由信号的后续放大引起的杂散发射。在优选实施例中，本发明的预失真技术结合在美国专利申请序列号（S-1）中描述的（频率无关）幅度和相位预失真技术来实现。第09 / 395,490号（“490应用”），其中频率相关的预失真对应于放大器失真，其具有与从载波频率的频率偏移成正比的幅度，并且相位偏移为±90° 载波频率的任一侧。频率相关的预失真是通过相对于时间对与预失真参数相对应的波形进行微分而产生的，然后将所得到的差分预失真参数应用于输入信号。根据实现情况，可以在模拟或数字域中区分波形。

摘要： A male coaxial connector adapted for receiving a female connection member. The male coaxial connector defines an axial direction along its major axis. The male coaxial connector includes a spring basket biased towards an open position which is positioned around a male connection member. The spring basket is adapted for engaging the female connection member. The male coaxial connector also includes a sleeve reciprocally positioned around the spring basket and the male connection member. The sleeve is movable in the axial direction with respect to the spring basket such that when the sleeve is in a forward position or rearward position with respect to the spring basket, the spring basket is in an open position. The female connection member can be released from or inserted into the spring basket when the spring basket is in its open position. When the sleeve is in a neutral position with respect to the spring basket, the sleeve is in engagement with the spring basket forcing the spring basket into a closed position such that the spring basket applies a radially compressive force on the female connection member. The male coaxial connector also includes a first spring positioned around the male connection member. The first spring provides an axial force on the male connection member which forces the male connection member into engagement with the female connection member.

摘要： A coaxial connector of the type wherein an inner connector member of a female connector is adapted for secure engagement with a connector member of a male connector. The coaxial connector is positioned around the connector member of the male connector and the connector member of the female connector when the coaxial connector is in its locked position. A spring basket with an angular frontal surface is positioned around the connection member of the male connector. A sleeve with an angular internal surface for engaging the angular frontal surface of the spring basket is reciprically positioned around the spring basket and the connection member of the male connector. The sleeve has at least one locking groove that extends substantially parallel to the major axis along a portion of the body thereof. A spring nut is provided with a hollow front end disposed within the sleeve and at least one upstanding locking finger disposed within the at least one locking grove of the sleeve. A spring is partially disposed within the hollow front end of the spring nut, and the spring is positioned between the spring nut and the connection member of the male connector respectively such that when the spring nut is pushed in a forward axial direction relative to the sleeve to lock the coaxial connector, the spring is compressed and the 15 internal angular surface of the sleeve engages the angular frontal surface of the spring basket forcing the spring basket to apply a radially inward force on the connection member of the female connector, holding the female connector in place. The spring provides an axial force on the connection member of the male connector and forces the connection member of the male connector into engagement with the connection member of the female connector.

摘要： A hog-horn antenna for producing two orthogonally polarized signals. The elevation plane pattern of each signal can be made to have virtually any shape, but is typically of a substantially cosecant-squared shape. In providing for the dual-polarization capability, the hog-horn antenna is designed to produce substantially equal gains for orthogonal polarizations, either simultaneously or separately. Two techniques to substantially equate the elevation plane radiation patterns of the two polarizations include corrugating or absorber-lining the surfaces of portions of the hog-horn antenna. Azimuthal pattern control may be achieved by corrugated/absorber lined flanges.
