Overview

The EROFLEX WEINSCHEL Model 3M and 4M are fixed coaxial attenuators designed to meet environmental requirements of MIL-DTL-3933. They feature rugged injection molded connectors, passivated stainless steel bodies, and gold plated beryllium copper contacts.

Key Specifications

The attenuators have a power rating of 2 watts average to 25°C ambient, derated linearly to 0.5 watts at 125°C, and a peak power handling of 500 watts (5 μsec pulse width; 0.2% duty cycle). The temperature range is -55°C to +125°C.

The nominal impedance is 50 ohms, and the maximum deviation over frequency is ±0.30 dB. The physical dimensions vary depending on the attenuation value, with a maximum diameter of 7/16 inch (11 mm) for the Model 3M and 1/2 inch (13 mm) for the Model 4M.

Typical Performance

The typical attenuation performance of the Model 4M-10 is shown, with a maximum SWR of 1.15 from dc to 1.15 GHz, 1.20 from 4 to 8 GHz, and 1.25 from 8 to 12.4 GHz.
