PE70A4000

Overview

The PE70A4000 is a 6-bit TTL controlled programmable attenuator manufactured by Pasternack. It provides a maximum attenuation of 31.5 dB with 0.5 dB step resolution. The device operates within a frequency range from DC to 13 GHz and utilizes SMA female connectors. It is designed for applications requiring precise RF signal control in high-frequency environments.

Feature Summary

• TTL controlled programmable operation
• 6-bit resolution with 0.5 dB steps
• SMA female connector interface

Applications

• RF test and measurement systems
• Automated production testing equipment
• Signal processing circuits

Procurement Notes

Verify the specific datasheet version for accurate electrical parameters before integration. Confirm that the TTL logic levels match the controlling system's output specifications. Ensure the SMA connector mating requirements are compatible with existing cabling infrastructure to maintain signal integrity.

Selection Notes

Select this model when a programmable solution with fine 0.5 dB resolution is required up to 13 GHz. It serves as an alternative to fixed attenuators where variable signal adjustment is necessary. Consider the physical size and weight constraints relative to similar Pasternack series components.

Part Context

This component belongs to the Pasternack RF Variable Attenuators series, specifically categorized under Connectorized Attenuators. It complements other programmable models like the PE70A8007, offering a distinct frequency range and attenuation profile suitable for mid-range microwave applications.

Replacement Considerations

Direct substitutes include the PE70A8007 (63 dB, 18 GHz) or generic 6-bit TTL attenuators from other manufacturers. Verify connector type compatibility and ensure the replacement supports the required 0.5 dB step resolution and frequency range.
