IFR Aeroflex Weinschel 82-30-34 High Power Fixed Coaxial Attenuator

The IFR Aeroflex Weinschel 82-30-34 is a high-power fixed coaxial attenuator designed for precise signal attenuation in RF and microwave test systems. Operating from DC to 18 GHz, this 30 dB attenuator delivers 50 watts average power and 5 kW peak power handling with ±0.5 dB accuracy across its operating range. Built around 50 ohm impedance and housed in stainless steel, it maintains excellent return loss performance: 1.15:1 maximum VSWR from DC to 10 GHz and 1.25:1 maximum from 10 GHz to 18 GHz. Type N male-to-female connectors ensure reliable integration into standard RF test benches. Insertion loss is limited to 0.25 dB maximum excluding the 30 dB attenuation value. Temperature stable across -55 °C to +125 °C, this attenuator suits demanding telecommunications, radar, and RF measurement applications where controlled power reduction and signal integrity are critical.
