PE43205B-Z

Overview

The PE43205B-Z is a 50-ohm, 2-bit digital step attenuator from pSemi’s UltraCMOS series. It operates within a frequency range of 35 MHz to 6 GHz and provides an attenuation range of 0 dB to 18 dB. The device features a maximum insertion loss of 1.05 dB and utilizes HaRP technology for fast switching. It is housed in a 12-WFQFN package with an exposed pad, supporting surface-mount installation. The component functions on a supply voltage between 2.3 V and 5.5 V and withstands operating temperatures from -40°C to +105°C.

Feature Summary

• Utilizes HaRP technology for high-performance RF signal control
• Provides digitally controlled attenuation steps via 2-bit interface
• Supports wide frequency operation up to 6 GHz
• Designed for low insertion loss and fast switching speeds

Applications

• 3G/4G wireless infrastructure systems
• RF test and measurement equipment
• Signal conditioning in communication modules

Procurement Notes

Verify the specific suffix 'B-Z' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering quantity aligns with the factory pack size of 3,000 units or available cut-tape options. Confirm that the 12-WFQFN package dimensions match the target PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when a compact, 2-bit digital attenuation solution is required for frequencies up to 6 GHz. The choice is driven by the need for low insertion loss and wide temperature tolerance. Consider the 12-WFQFN package constraints and the requirement for a 2.3 V to 5.5 V control voltage range during circuit design integration.

Part Context

The PE43205B-Z belongs to the UltraCMOS family of RF attenuators from pSemi. This series integrates silicon-based technology with HaRP enhancements to deliver precise attenuation control. The part serves as a key component in modern wireless infrastructure, offering a balance of performance and size efficiency compared to older analog attenuation methods.

Replacement Considerations

The base model PE43205 shares identical electrical specifications. Verify if the 'B-Z' suffix denotes specific tape-and-reel packaging or environmental compliance variations rather than functional differences before substituting.
