Medium Power Coaxial Attenuators (2 to 50 Watts)
Spectrum Control’s Medium Power Coaxial Attenuators deliver industry-leading performance across the 5-watt to 50-watt range, featuring an ultra-low 1.1:1 VSWR and strict ±0.5 dB flatness. Engineered for operational frequencies up to 40 GHz, these ruggedized components are specifically designed to handle increased thermal loads without exhibiting power coefficient degradation or attenuation drift. They maintain full electrical integrity across extreme defense and aerospace temperature ranges from -65°C to +125°C.
In medium-power RF signal chains, thermal dissipation and reflection management are critical to system reliability. Poor VSWR performance creates backward-traveling reflected power that can overdrive sensitive components such as power amplifiers (PAs), pushing them beyond their safe operating limits. By providing a nearly invisible, reflection-free path, Spectrum Control attenuators eliminate standing waves and amplitude ripple. This preserves phase linearity and spectral purity in high-demand radar, electronic warfare (EW), and commercial communication systems.
Maintaining tight attenuation flatness across wide bandwidths also prevents amplitude distortion and improper path modulation. Our precision-characterized designs eliminate the group delay variations and unexpected signal reshaping commonly found in inferior hardware. With hundreds of high-reliability configurations available, these medium-power solutions deliver the thermal stability and predictable attenuation accuracy required for critical system integration.
About Coaxial RF Attenuators
To perform effectively in an RF chain, a coaxial attenuator must provide repeatable signal reduction while remaining nearly invisible to the RF signal passing through the circuit. VSWR performance is critical to maintaining a reflection-free signal path. Reflections can distort waveform amplitude and introduce unintended effects such as phase distortion or phase shift, often resulting from poor attenuator VSWR performance. Lower-cost, poorly designed attenuators can create standing waves or attenuation ripple, leading RF designers to troubleshoot nonexistent system issues when the true cause is inadequate attenuator performance.
Reflected power is not simply absorbed within the RF chain; it can travel backward and create additional reflections that push active devices, such as amplifiers, beyond their intended operating limits.
Spectrum Control Fixed Attenuators
Spectrum Control’s superior VSWR coaxial attenuators help preserve phase linearity and spectral purity, with performance extending up to 50 GHz for demanding high-frequency applications. Ultra-flat attenuation is another critical parameter, ensuring consistent and precise attenuation across frequency. Variations in attenuation can reshape signals, leading to over- or under-modulation, while amplitude ripple combined with group delay variations from poor VSWR can negatively impact radar, communications, and RF modulation systems.
