ATT-20 Attenuator 20 dB 50 Ohm Impedance DC to 4 GHz Frequency 1 W Power Rating

The Siglent ATT-20 is a broadband 20 dB passive attenuator designed to reduce signal levels or protect sensitive RF equipment like spectrum analyzers and signal generators. It operates across a frequency range of DC to 4 GHz, supports a nominal 50 Ohm impedance, and handles up to 1 watt of continuous RF power. With a VSWR ≤ 1.2:1, the ATT-20 ensures minimal signal reflection and excellent transmission integrity. Built in a compact and durable metal housing, this attenuator provides dependable performance in both bench and field test environments. It is ideal for signal conditioning and input protection applications where high-frequency precision and robust build quality are required.
