PE70A8009

Overview

The PE70A8009 is a USB-controlled programmable attenuator manufactured by Pasternack. It provides an attenuation range of 0 to 95.5 dB with 0.5 dB resolution steps. The device operates within a frequency range of 200 MHz to 6 GHz and features SMA female connectors. It has a 50 Ohm impedance and supports up to 1 Watt of power handling.

Feature Summary

• USB interface for digital control
• High-resolution step adjustment
• Wideband RF performance

Applications

• RF test and measurement systems
• Automated production testing
• Signal chain calibration

Procurement Notes

Verify the specific firmware version and USB communication protocol compatibility with your host controller before integration. Confirm that the operating environment temperature falls within the specified limits to ensure stable attenuation accuracy. Check for any required driver software updates from the manufacturer to maintain reliable data exchange over the USB connection.

Selection Notes

Select this model when precise, digitally controlled attenuation is required in the 200 MHz to 6 GHz band. It is suitable for applications needing fine 0.5 dB resolution steps rather than coarse fixed values. Ensure the system can accommodate the physical size and weight of the module compared to discrete attenuators.

Part Context

This component belongs to Pasternack's line of programmable RF attenuators designed for automated environments. Unlike manual or fixed attenuators, it allows remote adjustment via USB, enabling dynamic signal level management in complex test setups without physical intervention.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific programmable model. Consider other Pasternack programmable attenuators if different connector types or frequency ranges are needed, but verify interface compatibility.
