摘要： A radio frequency filter is provided comprising at least one resonant chamber (2'') that comprises a respective tuning assembly, in which the resonant chamber (2'') is at least partially filled by the respective tuning assembly and a granular dielectric material (3), and in which the tuning assembly comprises a tuning screw (14'') within an enclosure comprising dielectric material, the enclosure providing an air pocket (23) in the granular dielectric material (3) within which the tuning screw (14'') is movable. In this way, the electrical or mechanical performance of the resonator is not compromised due to a non-uniform density of dielectric powder as would otherwise occur due to the screw pressing the powder. In consequence, the electrical performance of the filter is not compromised.

摘要： Antenna apparatus and a method of providing antenna apparatus. The apparatus comprising: a parabolic dish operable to collect and direct a satellite spectrum electromagnetic signal towards a focal point of the parabolic dish; a converter located at the focal point operable to convert the satellite spectrum electromagnetic signal to an electrical signal, the converter being coupleable to cabling for carrying the electrical signal; wherein the antenna apparatus further comprises: a white space electromagnetic signal radiating element arranged to use the parabolic dish as a white space electromagnetic signal reflector and coupleable to cabling for carrying electrical signals to and from the white space electromagnetic signal radiating element. Aspects recognise that a typical satellite antenna apparatus comprising a parabolic dish and converter, can also act as a part of a white spectrum antenna. In particular, providing a white space spectrum radiating element and positioning it such that the parabolic dish of the satellite antenna can be used as a reflector, a highly directional, high gain white space antenna may be formed. Allowing the combined antenna apparatus to be connectable to suitable feed lines can allow a signal to be fed to, and taken from, each of the two antenna provided as a single piece of antenna apparatus.

摘要： A resonator comprises a substrate and a body mounted on the substrate. The arrangement of the body and the substrate defines a resonant cavity. The resonator further comprises a stub which extends into the resonant cavity. The resonant cavity has a capacitance predominantly defined by a capacitance gap between the stub and a surface of the resonant cavity. The resonator further comprises an alignment error reducing structure operable to prevent more than one component mounting induced variation in the capacitance gap.

摘要： An antenna array and a method are disclosed. The antenna array comprises: a plurality of active antenna elements, each active antenna element being separated by a predetermined first spacing distance; and a plurality of passive antenna elements, each passive antenna element being separated by a predetermined second spacing distance. By providing both active and passive antenna elements, multiple networks can be supported by the same antenna array. Providing a dual network antenna significantly simplifies base station provision since existing base station sites may be reused more readily. Also, the number of antenna arrays which need to be provided at those base stations sites may be significantly reduced, thereby reducing mast head congestion and also reducing mast head loadings since the mass of the dual antenna array and its wind loading characteristics will be significantly less than that of two separate antenna arrays.

摘要： A power amplifier adapted to operate with simultaneous high efficiency and high linearity by using a RF feedback path to create an input predistortion signal. This power amplifier mainly includes a main amplifier (MA21), two splitters (SP21, SP31), one combiner (CO21), one subtracter (SU21), two phase shifters (PH21, PH31), one attenuator (AT21) and one error amplifier (EA21). The splitters, subtracter and combiner are designed in the form of 90-degree or quadrature hybrid couplers. A quadrature hybrid can be implemented with any lumped or transmission-line elements and has an important advantage compared to the in-phase splitter that at equal values of reflection coefficients from loads connected to the in phase and 90° phase shift terminals, the reflection wave is lacking at the main input terminal and, consequently, the input voltage standing wave ratio of a quadrature hybrid does not depend on the equal load mismatch level.

摘要： There is provided a small cell base station for use in a communications network having a small cell gateway. The small cell base station comprises: an uplink detector operable to monitor an RF uplink signal; a downlink detector operable to monitor an RF downlink signal; and a microcontroller in communication with the uplink detector and the downlink detector, operable to determine if the RF uplink signal satisfies a threshold condition based on the output of the uplink detector, wherein upon determining that the threshold condition is satisfied, the microcontroller is operable to transition the small cell base station to an active mode; determine if the RF downlink signal has been absent for a predetermined period of time, wherein upon determining that the RF downlink signal has been absent for a predetermined period of time, the microcontroller is operable to transition the small cell base station to a sleep mode; and optimise the threshold condition based on the occurrence, duration and/or success of transitioning the small cell base station to the active mode.
