In the world of RF and microwave testing, precision and repeatability are non-negotiable. Today, we’re highlighting one of our core high-performance components: the Manual Step Attenuator (also known as a Rotary or Drum-type Attenuator). Designed for engineers who require reliable signal leveling and attenuation in a compact, manual format, this series continues to be a […]

Reliable Performance for Demanding RF and Microwave Test Environments In RF testing and microwave systems where signal integrity and transmission accuracy are critical, Fasnwave introduces the High-Precision Armored RF Cable Assembly Series — engineered with an integrated armored design and exceptional electrical and mechanical performance, making it a trusted solution for the most demanding applications.

Filters are widely used in RF systems and can be classified based on their structural forms, such as LC filters, dielectric filters, cavity filters, microstrip filters, and waveguide filters. Cavity filters, in particular, offer advantages such as high Q-factor, low insertion loss, and high power capacity, making them widely used in communication systems. This article

Military Cavity filters in Passband 18200MHz± 500MHz Our this series cavity filters utilize rectangular or cylindrical metal-rod resonance oscillation with coaxial cavity, interdigital, or combline coupling structures. High-quality factor (high-Q) capacitive loading is integrated to ensure superior power handling performance. The resonance cavity length is less than one-quarter wavelength along with compact size, long Parasitic pass
