Anritsu 42N50-20 – DC-18GHz N(m-f) Attenuator, 20dB, 5 Watt

The Anritsu 42N50-20 is a fixed coaxial attenuator that reduces RF signal levels across DC to 18 GHz with 20 dB of attenuation. Rated for 5 Watts maximum input power, this 50 Ohm attenuator features N-type connectors (male input, female output) and operates bidirectionally, allowing flexible integration into test systems regardless of signal direction. Built for durability and stable attenuation performance, the 42N50-20 serves laboratory and field measurement applications where precise signal control is required.
