PE70A3902

Overview

The PE70A3902 is a USB-controlled programmable attenuator manufactured by Pasternack. It provides an attenuation range of 0 to 95 dB with 1 dB resolution steps. The device operates within a frequency range of 200 MHz to 6 GHz and features SMA female connectors for both input and output interfaces. Designed as an in-line module, it supports 50 Ohm impedance systems. This component enables precise digital control of RF signal levels through a USB interface, suitable for automated test environments requiring variable attenuation.

Feature Summary

• USB interface for digital control and programming
• Programmable attenuation from 0 to 95 dB
• 1 dB step resolution for precise signal adjustment
• SMA female connectorized in-line module design

Applications

• Automated RF test and measurement systems
• Signal level adjustment in communication equipment
• Calibration setups requiring variable attenuation
• Research and development laboratory instrumentation

Procurement Notes

Verify the specific datasheet version and firmware compatibility before integration. Confirm that the host system supports the required USB communication protocol. Ensure the operating environment stays within the specified temperature and power limits. Check for any regional distribution restrictions or availability updates from authorized suppliers.

Selection Notes

Select this model when digital programmability is required over manual adjustment. Compare against fixed attenuators if static values suffice. Consider the 200 MHz lower frequency limit; use alternative models for DC or sub-200 MHz applications. Verify that the 95 dB maximum range meets the system's dynamic requirements.

Part Context

This part belongs to Pasternack's line of USB-controlled programmable attenuators. It complements their broader portfolio of RF interconnects and variable attenuators. The series targets applications needing remote control capabilities rather than manual knob adjustments, integrating seamlessly into computer-controlled test benches.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the USB control interface, frequency range, and connector type exactly.
