PE70A2008

Overview

The PE70A2008 is an active voltage variable attenuator module manufactured by Pasternack, designed for high-frequency RF applications. It operates within a frequency range of 18 GHz to 26 GHz and provides a maximum attenuation of 30 dB. The component features SMA connectors and maintains a system impedance of 50 Ohms. This unit is constructed to reduce the amplitude level of incoming signals through voltage control mechanisms, suitable for integration into modular RF systems requiring precise signal management at microwave frequencies.

Feature Summary

• Active voltage-controlled operation for dynamic signal amplitude adjustment
• High-frequency performance covering the 18 GHz to 26 GHz spectrum
• Modular construction with SMA interface connectivity

Applications

• Microwave communication systems requiring variable gain control
• RF test and measurement instrumentation modules
• Signal processing circuits operating in the K-band range

Procurement Notes

Verify the specific datasheet requirements for control voltage levels and biasing conditions before integration. Confirm that the SMA connector polarity matches the system design. Ensure thermal management solutions are adequate for the module's power dissipation characteristics during continuous operation in the target environment.

Selection Notes

Select this model when variable attenuation is required rather than fixed loss. Consider the 18-26 GHz operational bandwidth against system frequency needs. Evaluate the need for active voltage control versus passive step attenuators based on automation requirements. Verify compatibility with existing SMA infrastructure and control circuitry.

Part Context

This component belongs to Pasternack's portfolio of RF attenuators, specifically categorized as active voltage variable attenuators. Unlike fixed attenuators or rotary step types, this module offers continuous adjustability via voltage input. It serves as a specialized solution for dynamic signal conditioning in high-frequency electronic systems where precise amplitude modulation is critical.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Pasternack models offering similar frequency ranges and attenuation capabilities if direct replacement is unavailable.
