PE70A8007

Overview

The Pasternack PE70A8007 is a TTL controlled programmable attenuator designed for high-frequency applications. It provides an attenuation range of 0 to 63 dB with precise 0.5 dB step resolution. The device operates effectively from 100 MHz to 18 GHz, ensuring signal integrity across a broad spectrum. It features SMA female connectors for reliable interconnection and is rated for 2 watts of power handling up to 2.2 GHz. This component is part of the RF Variable Attenuators series and is packaged in bulk.

Feature Summary

• TTL logic interface enables digital control for automated test systems
• High-resolution 0.5 dB step increments allow for fine-tuned signal adjustment
• Broadband operation supports frequencies extending up to 18 GHz

Applications

• Automated radio frequency test and measurement setups
• Signal generation and conditioning in communication systems
• Calibration of RF instrumentation requiring precise attenuation levels

Procurement Notes

Verify that the specific unit matches the PE70A8007 designation to ensure compatibility with TTL control signals. Confirm the SMA female connector type aligns with existing system interfaces. Check the datasheet for updated thermal ratings if operating near the 2-watt limit at higher frequencies. Ensure environmental conditions meet the manufacturer's specifications for long-term reliability.

Selection Notes

Select this model when digital programmability is required rather than manual rotary or push-button adjustments. It is suitable for applications needing rapid, repeatable attenuation changes within a laboratory or production environment. Consider the 18 GHz upper frequency limit against system requirements. Evaluate the need for 0.5 dB resolution versus coarser steps available in other series members.

Part Context

This component belongs to the Pasternack RF Variable Attenuators series, specifically designed as a connectorized attenuator. It differs from mechanical step attenuators by utilizing electronic switching controlled via TTL inputs. The product is categorized under Interconnect Attenuators and is distinct from fixed-value attenuators due to its variable nature and digital control capabilities.

Replacement Considerations

No direct public substitute part numbers are documented for this specific TTL-controlled configuration. Alternative models may require different control interfaces such as analog voltage or manual operation. Verify functional equivalence regarding frequency range and connector types before considering any cross-reference.
