PE43713B-Z

Overview

The PE43713B-Z is a 50-ohm, 7-bit RF digital step attenuator from pSemi’s UltraCMOS series. It operates within a frequency range of 9 kHz to 6 GHz and provides a maximum attenuation of 31.75 dB. The device features flexible attenuation steps of 0.25 dB, 0.5 dB, and 1.0 dB. Key electrical parameters include an insertion loss of 2.45 dB and a supply voltage range of 2.3 V to 5.5 V. It supports both parallel and serial programming interfaces with serial addressability. The component is housed in a 32-lead QFN package (5 × 5 mm) and is rated for operation between -40 °C and +105 °C.

Feature Summary

• Glitch-less attenuation state transitions ensure signal integrity during adjustments.
• Monotonicity is maintained across specific frequency bands: 0.25 dB up to 4 GHz, 0.5 dB up to 5 GHz, and 1 dB up to 6 GHz.
• Supports both parallel and serial control interfaces with serial addressability capabilities.

Applications

• Test and measurement equipment
• General purpose RF attenuator circuits
• Wireless and RF communication systems

Procurement Notes

Verify the suffix 'Z' indicates RoHS compliance status as per manufacturer specifications. Confirm the 32-VFQFN package dimensions match the design footprint. Ensure the operating temperature range meets the environmental requirements of the target application. Validate that the 2.3 V to 5.5 V supply voltage aligns with the system power architecture.

Selection Notes

Select this component when a wide frequency range extending to 6 GHz is required. The flexible step sizes allow for precise gain control in complex RF chains. Consider the 32-lead QFN package for compact board layouts. Verify compatibility with the chosen control interface, whether parallel or serial, before integration into the design.

Part Context

The PE43713B-Z belongs to pSemi’s UltraCMOS family, utilizing HaRP technology for enhanced performance. It is part of the broader PE43713 product line, designed for high-reliability RF applications. The device represents a solution for digital attenuation in modern wireless infrastructure and test instruments requiring broad bandwidth and low distortion.

Replacement Considerations

The part number alias PE43713 refers to the same functional device without the 'B-Z' suffix variations. Verify if alternative suffixes are available for different packaging or compliance options. Cross-reference with other UltraCMOS series attenuators if pinout or control logic differences exist.
