Does 10W refer to continuous power or peak power?
100W is the continuous power rating, suitable for long-term stable operation. Short-term peak power may be slightly higher, but must not exceed thermal design limits.
Is it suitable for outdoor or high-temperature environments?
Yes, its aluminum housing and heat sink fins are designed to withstand high temperatures. For extended lifespan, install in a well-ventilated area.
Does attenuation drift with temperature changes?
Uses high-stability thin-film resistors with an extremely low temperature coefficient. Attenuation varies by less than ±0.3 dB from -40°C to +85°C, meeting industrial-grade precision requirements.
How to install correctly to avoid signal reflection?
Please ensureConnectorTighten to the specified torque (typically 12-15 in-lbs) and use a matching 50Ω cable for the load to avoid impedance mismatch, which can increase the VSWR.
