Abstract: The invention relates to cavity resonators for usage in the field of telecommunications, notably radio frequency and microwave radio communications. A cavity resonator operable to exhibit a resonance frequency is disclosed, comprising a housing (41) made of a material with a first thermal expansion coefficient in the first direction and a first plate (42) made of a material with a first thermal expansion coefficient in a second direction, essentially perpendicular to the first direction. The cavity resonator further comprises an inner conductor (44) made of a material with a second thermal expansion coefficient in the first direction and a second plate (40) made of the same material as the inner conductor (44) with a second thermal expansion coefficient in the second direction. The cavity resonator is characterized in that the first and the second thermal expansion coefficient in the second direction are such that the mechanical stress at the joint between the first plate (42) and the housing (41) and the mechanical stress at the joint between the second plate (40) and the housing (41) caused by a significant temperature change is essentially zero. Furthermore the first and the second thermal expansion coefficient in the first direction are such that the resonance frequency remains within a preset bound, which is essentially zero, over the significant temperature change. Furthermore, as method for making such a cavity resonator is disclosed.

Abstract: The invention concerns a radio frequency transmitter (RFT) and a method of amplifying a radio frequency input signal (S IN ) in the radio frequency transmitter (RFT). The radio frequency transmitter (RFT) comprises a digital signal generator (DSG) with a generation unit (GU) adapted to generate a pulsed bit stream signal and a switch mode power amplifier (SMPA) with a transistor circuit (PT) adapted to amplify the radio frequency input signal (S IN ). The digital signal generator (DSG) further comprises a control unit (CU) adapted to detect in said pulsed bit stream signal a sequence of a constant signal height longer than a predefined threshold. The control unit (CU) is also adapted to initiate, upon detection of said sequence, a generation of a modified pulsed bit stream signal by an insertion of one or more notches in said sequence. Said notches interrupt said sequence by a signal of a signal height different from the signal height of the sequence. The radio frequency transmitter (RFT) further comprises connecting means (CM) adapted to provide said transistor circuit (PT) with said modified pulsed bit stream signal as the radio frequency input signal (S IN ).
