Waveguide filters absorb rather than
reflect
New absorptive harmonic waveguide filters avoid the potential damage that reflective filters can cause when used with high-power microwave amplifiers.
Microwave and RF component specialist Link Microtek has introduced a new range of in-house manufactured absorptive harmonic waveguide filters, which, when used with high-power microwave amplifiers, avoid the potential damage that reflective filters can cause Known as the AMQ-HARM series, the new filters are designed to absorb signals with harmonic frequencies higher than the specified passband, rather than reflecting them back to the amplifier

Integrated VCOs pack in more microwave functions
Now available from Link Microtek is a new range of low-cost, plastic-packaged MMIC voltage controlled oscillators (VCOs) that feature a high level of integrated functionality.
Manufactured from lightweight aluminium, these compact filters are available in waveguide sizes from WR137 to WR62 for applications in the frequency range 5.8 to 18.4GHz, with harmonic frequencies up to 40GHz.
They feature a sealed, pressure-tight design that makes them particularly suitable for use in high-power transmitters such as radar TWTAs (travelling-wave tube amplifiers), where pulsed powers are commonly in the tens of kilowatts range.
In addition, the AMQ-HARM filters are likely to be of interest to any EMC test houses equipped with high-power broadband microwave amplifiers to reduce unwanted higher frequency signals.
