Harmonic-absorption Filters from Link Microtek
Link Microtek is pleased to announce today a new series of eight waveguide harmonic-absorption filters that are designed to safely eliminate harmonics from the output of a high-power microwave amplifier, thereby ensuring that only fundamental frequencies are transmitted and that there are no potentially damaging reflections back into the system.
The Utilising a so-called ‘compact’ design with the absorption elements located on the broad wall of the device, the filters achieve a stop-band rejection of better than 20dB up to the third harmonic. They have a power handling capacity of at least 200W, a low insertion loss of 0.25dB and a low VSWR of 1.1:1 for the pass band.
As well as being ideal for use in standards laboratories and test houses, the devices are also suitable for operational applications in radar and communications systems, depending on the waveguide size selected.
Designed and manufactured at Link Microtek’s premises in the centre of Basingstoke, the AMQ-HARM-T1 filters are fabricated from Alochromed aluminium to minimise weight and are finished in black satin paint.
