Overview
The HMC973LP3ETR is a voltage-controlled RF attenuator manufactured by Analog Devices Inc. It operates within a frequency range of 500 MHz to 6 GHz with a 50 Ohms impedance. The device provides an attenuation range of 0 dB to 28 dB and features an insertion loss of 5.6 dB. It is housed in a 16-VFQFN package with an exposed pad, suitable for surface mount installation. The component functions as a single-channel variable attenuator designed for precision signal control applications.
Feature Summary
- Voltage-controlled attenuation mechanism for precise signal level adjustment
- Wide operational bandwidth covering microwave frequencies up to 6 GHz
- Integrated design utilizing GaAs technology for high performance
Applications
- RF signal chain management in wireless communication systems
- Test and measurement equipment requiring variable attenuation
- Phased array antenna beamforming networks
Procurement Notes
Verify current availability status as the HMC973LP3ETR is listed as obsolete and no longer manufactured by Analog Devices Inc. Confirm compatibility with direct replacement parts such as the HMC973ALP3E series if sourcing new inventory is required. Ensure all technical specifications match system requirements before finalizing procurement decisions for legacy components.
Selection Notes
Select this component for applications requiring wideband voltage-controlled attenuation between 500 MHz and 6 GHz. Consider the 16-VFQFN package size for space-constrained designs. Evaluate the 5.6 dB insertion loss and 28 dB maximum attenuation against system link budget requirements. Verify thermal management capabilities given the QFN package type.
Part Context
The HMC973LP3ETR belongs to the HMC973 family of voltage-variable attenuators from Analog Devices Inc. This series is designed for RF and IF applications requiring precise gain control. The LP3ETR suffix indicates a specific tape-and-reel packaging variant of the base HMC973 product line, optimized for automated surface-mount assembly processes.
Replacement Considerations
Direct substitutes include HMC973ALP3E and HMC973ALP3ETR. These alternatives offer identical functional specifications and pinouts, facilitating drop-in replacements for existing designs without circuit modifications.
