PE70A1043S

Overview

The Pasternack PE70A1043S is a push-button step attenuator featuring SMA female connectors. It provides an attenuation range from 0 to 90 dB with 1 dB resolution steps. The device operates within a frequency range of DC to 3 GHz and maintains a 50 Ohm impedance. It has a power rating of 2 Watts and a VSWR of 1.5:1. The unit weighs approximately 85.275 grams.

Feature Summary

• Push-button mechanical stepping mechanism for precise attenuation control
• High isolation performance across the specified frequency band
• Robust SMA connector interface for reliable signal transmission

Applications

• RF test and measurement setups requiring variable signal reduction
• Communication system signal level adjustment
• Laboratory equipment calibration and testing

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct connector type and power rating. Confirm lead times directly with authorized distributors as manufacturing schedules vary. Check RoHS compliance status if required for your assembly process. Ensure the SMA connectors match your existing cable infrastructure specifications before purchase.

Selection Notes

Select this model when a wide dynamic range up to 90 dB is required in a compact form factor. The 1 dB step resolution allows for fine-tuning signal levels in sensitive applications. Consider the 2 Watt power handling capability for moderate power signals. The SMA interface ensures compatibility with standard RF test equipment and cabling systems commonly used in laboratory environments.

Part Context

This component belongs to Pasternack's line of connectorized attenuators designed for RF and microwave applications. It complements their broader portfolio of passive RF components, including cables, adapters, and surge protectors. The series supports various frequency ranges and power ratings to meet diverse engineering requirements for signal integrity and attenuation precision.

Replacement Considerations

Check for equivalent models with identical SMA female interfaces and 90 dB maximum attenuation. Verify that substitute parts maintain the same 1 dB step resolution and 3 GHz frequency limit. Ensure power handling capabilities match or exceed the 2 Watt rating. Confirm physical dimensions fit within the intended enclosure space.
