PE70A8012

Overview

The PE70A8012 is a USB-controlled programmable RF attenuator module manufactured by Pasternack. It provides an attenuation range of 0 dB to 63 dB with 0.5 dB step resolution. The device operates within a frequency range of 100 MHz to 18 GHz and features SMA female connectors. It maintains a characteristic impedance of 50 Ohms and supports a maximum VSWR of 2. This inline module allows for precise digital control of signal levels in high-frequency applications.

Feature Summary

• USB interface for programmable attenuation control
• High-frequency operation up to 18 GHz
• Fine 0.5 dB step resolution for precision tuning

Applications

• RF test and measurement instrumentation
• Wireless communication system testing
• Automated production test environments

Procurement Notes

Verify the specific connector gender and cable assembly requirements before ordering, as this is an inline module. Confirm that the host system provides the necessary USB power and data interface for programming. Ensure the operating environment stays within the specified temperature limits to maintain performance accuracy. Check for any required driver software compatibility with the target control computer.

Selection Notes

Select this model when digital control over attenuation values is required rather than manual adjustment. The 0.5 dB step size offers higher precision compared to standard 1 dB or 5 dB steps. Consider the 18 GHz upper frequency limit to ensure it covers the entire operational bandwidth of the DUT. Verify that the 50 Ohm impedance matches the rest of the RF chain to minimize reflections.

Part Context

This component belongs to Pasternack's line of USB-controlled programmable attenuators. These modules are designed to replace traditional manual variable attenuators in automated setups. They integrate digital logic with RF front-ends to provide remote adjustability. The series typically includes models with varying frequency ranges and maximum attenuation levels.

Replacement Considerations

Direct substitutes must support USB control and cover the 100 MHz to 18 GHz range. Manual attenuators cannot be used directly without additional control hardware. Other Pasternack models like the PE70A8011 may offer different step sizes or frequency ranges but require verification of pinout and protocol compatibility.
