The ACASOM Super BiasTee ingeniously combines two critical RF functions into a single, compact device: a high-performance Bias Tee and a precise Digital Attenuator. This dual functionality allows you to simultaneously deliver DC power to remote active antennas or amplifiers over the RF coaxial cable and finely adjust signal strength with a 5-bit digital attenuator ranging from 0dB to 31.5dB in 0.5dB steps. It is the ultimate tool for optimizing and simplifying your RF system setup, particularly for cellular, LTE, GPS, and ISM band applications.

Dual Core Functions:

Super Bias Tee: Provides clean, stable DC power injection (3-32V, up to 2A) directly through the RF cable, eliminating the need for separate power lines.
Integrated Digital Attenuator: Features an adjustable attenuation range from 0dB to 32dB, enabling perfect signal level matching to prevent receiver overload and optimize system performance.

KEY FEATURES

Dual-Function Design: Bias Tee + Digital Attenuator in one unit, saving space and cost.
Adjustable Power Supply: Input voltage range of 3V to 32V with maximum 2A output current, versatile for various active components.
Precise Signal Control: 5-bit digital attenuator allows for fine-grained signal adjustment (0dB to 31.5dB).
Broadband Performance: Operates across a wide 600-2000MHz frequency range.
High Efficiency: Low insertion loss (≤2.0dB) and excellent VSWR (≤1.3) ensure minimal signal degradation.
Visual Indicator: Built-in LED illuminates (Red) when DC voltage ≥5V is applied for clear status monitoring.
Rugged & Compact: Durable aluminum shell with a small footprint for easy deployment in any environment.
