Overview
The PE43204MLIBA-Z is a 2-bit digital step attenuator from pSemi’s UltraCMOS® HaRP™ family. It provides an attenuation range of 18 dB with 6 dB steps in a 50-ohm system. The device operates from 50 MHz to 3 GHz with a maximum insertion loss of 1.05 dB. It features a serial CMOS control interface and functions on a single supply voltage ranging from 2.3 V to 5.5 V. Packaged in a 12-pin QFN, it supports operation between -40°C and +105°C.
Feature Summary
- Utilizes patented UltraCMOS silicon-on-insulator technology for high linearity and low power consumption
- Features a serial-addressable CMOS control interface for simplified integration
- Maintains high attenuation accuracy over frequency and temperature variations
- Includes an on-board regulator ensuring performance stability independent of supply voltage
Applications
- Wireless communication base stations
- Test and measurement equipment
- RF signal conditioning circuits
Procurement Notes
Verify the specific suffix MLIBA against official pSemi documentation to confirm pinout and package dimensions. Confirm RoHS compliance status through current datasheets. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a compact 2-bit attenuation solution is required up to 3 GHz. Ensure the design accommodates the 12-pin QFN footprint and serial control logic. Verify that the 18 dB total range meets the system's dynamic requirements without excessive cascading.
Part Context
This part belongs to the PE4320x series of digital step attenuators manufactured by pSemi. These devices are designed for RF applications requiring precise gain control. The series leverages UltraCMOS technology to offer superior performance compared to traditional semiconductor processes.
Replacement Considerations
PE43205B-Z offers similar functionality but operates up to 6 GHz. Verify if the higher frequency capability is necessary and if the pinout remains compatible.
