Rotary Stepped Attenuators up to 40 GHz
Precision signal attenuation is essential in RF and microwave test systems, receiver chains, and power management applications. Rotary stepped attenuators offer manual or motorized control over signal loss with repeatable accuracy across wide frequency bands. These solutions span from DC through 40 GHz, addressing the expanding demand for calibrated attenuation in contemporary wireless and aerospace systems.
Technical Specifications
- Frequency Range: DC to 40 GHz continuous coverage
- Attenuation Steps: 0.1 dB, 1 dB, and 10 dB incremental settings
- Power Handling: Up to 25 Watts nominal input
- Connector Types: SMA, N-type, 3.5 mm, and 2.92 mm interfaces
- Configuration: Custom variants available for specialized requirements
- Form Factor: Compact rotary mechanism for laboratory and field deployment
The combination of fine-resolution 0.1 dB steps with coarser 10 dB increments enables efficient coverage of wide dynamic ranges. Multiple connector formats ensure compatibility with existing test benches and integrated subsystems without requiring intermediate adapters. Rotary operation provides tactile feedback and precise repeatability without external power supplies, making them invaluable for both automated test racks and portable measurement kits.
Applications
- 5G & 6G Testing: Component validation and receiver sensitivity measurements
- Millimeter-Wave: Signal path optimization in antenna test ranges
- SATCOM: Satellite ground station power control and link budget verification
- Defense & Aerospace: RF system calibration and verification
- Laboratory: LNA and HPA gain flatness and compression point determination
The extended frequency reach to 40 GHz positions these attenuators within the critical bands for satellite communications, millimeter-wave 5G NR systems, and emerging automotive radar platforms. The 25-Watt handling capacity suits applications ranging from low-level receiver testing to moderate-power transmitter characterization.
