PE70A5008

Overview

The PE70A5008 is a rotary step attenuator manufactured by Pasternack, designed for RF applications up to 3 GHz. It features SMA female connectors and provides an attenuation range of 0 to 95 dB with 1 dB resolution steps. The device operates at a 50 Ohm impedance and supports a maximum power rating of 2 Watts. Key electrical specifications include a typical VSWR of 1.4:1 and insertion loss characteristics consistent with its step configuration. It is engineered for cable mount installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides precise 1 dB step attenuation control via rotary mechanism
• Supports high isolation levels across the operational frequency band
• Features durable SMA female-to-female connector interface

Applications

• RF signal testing and measurement instrumentation
• Telecommunications equipment calibration
• Laboratory signal level adjustment
