Technical Specifications
Impedance: 75Ω. Attenuation value: 10dB nominal. Frequency range: DC to 3GHz. Attenuation tolerance: ±0.5dB. VSWR: <1.2:1. Power rating: 1W average. Operating temperature range: -40°C to +85°C. Connector style: TSL type both ends.
Functional Features
Precision resistive network provides accurate flat attenuation across frequency. Low VSWR minimizes signal reflection and system mismatch. Compact cylindrical design saves board and panel space. Metal housing provides shielding and durability. It suits both analog and digital RF transmission systems.
Application Scenarios
It is used in CATV headend systems, telecom transmission networks, RF test equipment, signal level matching, receiver input protection and test and measurement setups.
Performance Parameters
Frequency range: DC to 3GHz. Attenuation accuracy: ±0.5dB. VSWR: ≤1.2:1. Insertion loss: <0.3dB. Power handling: 1W average. Operating temperature range: -40°C to +85°C.
Material Composition
Body: nickel-plated brass. Inner conductor: beryllium copper. Dielectric: PTFE. Resistive elements: high-stability thin-film. Connectors: gold-plated contact surfaces.
Structural Characteristics
It features cylindrical coaxial construction, TSL bayonet connectors at both ends, internal resistive attenuation network, and sealed metal body.
Working Principle
It inserts a precision resistive network in series with the signal path that absorbs a portion of the RF signal energy as heat, reducing signal level by a fixed amount while maintaining characteristic impedance to minimize signal reflection.
Installation Requirements
Insert in-line with the signal path. Mate connectors fully and lock bayonet collar. Ensure correct cable impedance match. Mount away from heat sources. Support cable near connectors to avoid strain.
