Any tooling marks or imperfections in the material can later cause losses, reduced VSWR, and misalignment when connecting with outer waveguide components.<\/span><\/p>\n<p class=\"normal\"><span style=\"font-family: 'Arial','sans-serif'; color: windowtext;\">Partnering with a high quality source of <\/span><span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/www.pasternack.com\/nsearch.aspx?Category=Waveguide+Terminations^Waveguide+To+Coax+Adapters^Waveguide+Sections^Waveguide+Bends^Specialty+Waveguide+Antennas^Gain+Horns^Gain+Horns+with+Waveguide+to+Coax+Adapters^Waveguide+BandPass+Filters^Waveguide+Couplers^Waveguide+Detectors^Waveguide+Variable+Attenuators^Waveguide+Converter+Mixers^Waveguide+Power+Amplifiers^Waveguide+Twists^Waveguide+Transitions^Flexible+Waveguides^Waveguide+PIN+Diode+Switches^Waveguide+Gunn+Oscillators^Waveguide+Phase+Shifters^Waveguide+Bulkhead+Adapters&amp;sort=y\"><span style=\"font-family: 'Arial','sans-serif';\">waveguides<\/span><\/a><\/span><span style=\"font-family: 'Arial','sans-serif'; color: windowtext;\"> is paramount to ensuring optimal waveguide performance and system uptime.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The quality of the construction and materials used can have a large impact on the performance of a waveguide system, especially in microwave frequencies and high power applications.
