    • A circulator comprises a housing (10) in two halves (12, 11) with a ferrite (18) and associated magnet (16) in a central portion of a first one of the halves (12), the second housing-half (11) above the ferrite having a membrane (32) which is deformable by operation of an adjusting means (33) upon the membrane, so as to adjust the size of an airgap (26) between the membrane and the ferrite. The membrane is preferably the residual portion of the second housing-half following a milling operation to provide a recess (31), the recess accommodating the adjusting means in the form of, e.g., a screw. To further enhance predictability of the performance characteristics of the circulator, the ferrite is seated in a hollow (36) formed in the first housing-half and the securing of the ferrite to the first housing-half is by way of an adhesive applied between a lateral face (37) of the ferrite and a corresponding lateral face of the hollow.

    • A method of, and system for, reserving timeslots in a TDMA system of a type in which a plurality of subscriber units (CPE) use the same radio channel for transmission during different timeslots to a base station and in which the base station administers the radio channel centrally is disclosed. Subscribers units transfer, if appropriate, a transmission request to the base station in the form of a PN (pseudo-random noise) sequence (e.g. M-sequence, preferred gold, Katsami or orthogonal gold sequence). Transmission requests from different subscriber units can be identified at the base station using the PN sequence, reception time of the PN sequence and/or phase of the PN sequence.

    • The invention relates to a device for linearising a high-frequency amplifier. The inventive device comprises a pre-distorter (VV) that is connected upstream in relation to the amplifier (HV). Several phase (PS3, PS5) and dampening members (DG3, DG5) which can be variably controlled are provided in said pre-distorter. The aim of the invention is to suppress the intermodulation products as far as possible, whereby said products are generated by the amplifier (HV). A signal path (LZ2, PS, D, AGC, SU, BS, LV, R1) is provided which selects the intermodulation products from the amplifier output signal (RFO) by considering the input signal (IFI) of the pre-distorter (VV). The intermodulation products serve as the controlled variable (RG) for the variable phase (PS3, PS5) and dampening members (DG3, DG5) of the pre-distorter (VV).
