The Radiall R404370000 is a TNC male coaxial termination designed for precision RF applications requiring a 50Ω load. It operates from DC to 18 GHz with excellent VSWR performance: 1.08 maximum from DC to 4 GHz, 1.10 from 4 to 8 GHz, 1.15 from 8 to 12.4 GHz, and 1.20 from 12.4 to 18 GHz. The termination is rated for 2W average power at 25°C in free air, derating linearly to 0W at 125°C, and can handle 100W peak power (1 µs pulse, 1% duty cycle).
Constructed with a stainless steel passivated body, brass gold-plated center contact, and PTFE insulator, the R404370000 meets MIL-C-39012 standards. The thin film resistor on an alumina substrate ensures stable performance over the full operating temperature range of -55°C to +125°C. The coupling torque is specified at 265 N·cm, and the weight is 21.12 g.
This free-hanging, cap-style termination is suitable for terminating RF transmission lines in test equipment, communication systems, and aerospace applications. Its low VSWR and wide frequency range make it ideal for high-frequency signal integrity.
