Digital Attenuator Module LF-6GHz 0.5dB Step Accuracy Up to 31.5dB NC Attenuator Module

I. Ultra-High Precision & Wideband Coverage: ✅ 0.5dB Fine Stepping: 31.5dB total attenuation range, ultra-low ±0.25dB step error, precisely controlling signal strength. ✅ DC-6GHz Ultra-Wide Bandwidth: Supports the full frequency band from low frequency to 6GHz, meeting demanding scenarios such as 5G, radar, and satellite communications.

II. Flexible Dual-Mode Control: ✅ Serial/Parallel Dual Interfaces: Serial Mode: Three-wire (CLK/DATA/LE), saving control ports and supporting cascading multiple devices; Parallel Mode: 6-bit direct control word for real-time, fast response. ✅ Intelligent Power-On Memory: User-defined initial state eliminates the need for reconfiguration upon system restart.

III. Excellent Performance: ✅ High IP3 of +55dBm: Distortion-free processing of high-power signals, ensuring system linearity. ✅ Ultra-Low Insertion Loss: Only 2.2dB @ 3.5GHz, maximizing signal energy retention.

IV. Industrial-Grade Reliable Design: ✅ Fully integrated, no-matching required: QFN 4x4mm package, no external components required, plug-and-play. ✅ Double protection: Metal shielding for interference prevention + reverse polarity protection diode. ✅ Wide-range power supply: +3V or +5V single power supply, 5mA low power consumption, compatible with mainstream systems.
