The Quarktwin Technology Ltd. attenuator, part number R411801121, is designed for RF applications with a nominal attenuation of 1 dB across a frequency range of DC to 18 GHz. It features a 50-ohm impedance and is capable of handling a peak power of 100 W at 25¬8C for short durations (1 ¬µs, 1% duty cycle) and an average power of 2 W when free air cooled. The device has SMA connectors (male and female) compliant with MIL-C 39012 standards. The attenuator exhibits a voltage standing wave ratio (V.S.W.R) of 1.15 at DC to 4 GHz, increasing to 1.35 at 12.4 to 18 GHz. Deviation in attenuation is specified as ¬±0.30 dB for the lower frequency ranges, increasing to ¬±0.70 dB at the highest frequencies. It operates effectively within a temperature range of -55¬8C to +125¬8C, making it suitable for various environmental conditions. The construction includes a stainless steel body, beryllium copper contacts with gold plating, and a PTFE insulator, ensuring durability and reliability in performance.
