Wide frequency range from 20MHz to 4000MHz, covering various RF signals within this spectrum.
-
Low Insertion Loss
Only 0.36dB insertion loss ensures minimal signal energy loss during transmission.
-
Power Limiting
Handles up to 5W maximum input power to protect subsequent circuit components from power-amplifier signal leakage.
-
Wide Operating Temperature Range
Operates from -40°C to 85°C, ensuring reliable performance in various environmental conditions.
Used in 5G base stations and Wi-Fi signal amplifiers to limit received signal power and ensure normal operation of subsequent circuits.
Protects internal components in signal generators and spectrum analyzers while ensuring measurement accuracy.
Essential in airborne frequency-hopping RF front-end circuits to prevent damage to low-noise amplifier chips.
Provides accurate signal processing and feedback in motion control and sensor interfaces while protecting system components.
