Main Functions
Controlled Signal Reduction
Provides precise attenuation (3dB to 30dB) with tight tolerance (±0.5dB to ±1.3dB), enabling optimal signal level management in RF chains.
Impedance Matching & Reflection Control
Maintains 50Ω impedance and high return loss (≥19dB) to minimize signal reflections and ensure system stability.
Equipment Protection
Safeguards sensitive receivers from signal overload while maintaining ultra-low PIM performance to prevent interference.
Typical Application Scenarios
Cellular Base Station Optimization
Adjusts signal strength in 4G/5G macro/small cells (698-3800MHz) to balance amplifier loads and improve network efficiency.
Test & Measurement Calibration
Used in lab/field environments to calibrate instruments, simulate path loss, or troubleshoot signal chains with precise attenuation control.
DAS Signal Leveling
Ensures uniform coverage in distributed antenna systems (indoor/outdoor) by fine-tuning power distribution across multi-carrier frequencies.
Technical Features
High-Performance RF Characteristics
Delivers ultra-low PIM (≤-160dBc) and flat frequency response across 698-3800MHz, critical for modern high-density networks.
Precision Engineering
Offers six attenuation values (3/6/10/15/20/30dB) with industry-leading tolerance accuracy (±0.5dB at 3dB), ensuring reliable signal control.
Robust Outdoor Design
Features IP65 environmental protection, wide temperature resilience (-40°C to +65°C), and flexible wall/pole mounting. Compact housing (176x176x44.5mm) with N Male/Female connectors simplifies integration.
