Overview
The MA4VAT904-1061T is a voltage-controlled variable attenuator manufactured by MACOM Technology Solutions. It operates within a frequency range of 800 MHz to 1 GHz and provides a maximum attenuation value of 25 dB. The device utilizes HMIC PIN diode technology integrated with a 90-degree 3dB hybrid coupler. It is housed in an 8-SOIC package with a width of 3.90 mm. This component is designed for RF applications requiring precise signal level adjustment.
Feature Summary
- Integrates HMIC PIN diodes with a 90-degree 3dB hybrid coupler
- Voltage-controlled variable attenuation capability
- Operates in the 800 MHz to 1 GHz frequency band
Applications
- RF signal conditioning circuits
- Variable gain amplifier stages
- Test and measurement equipment
Procurement Notes
Verify the specific datasheet revision, as documentation indicates version V2 availability. Confirm RoHS compliance status, noting references to ROHS3 compliance in distributor listings. Ensure the 8-SOIC package dimensions match your PCB footprint requirements. Cross-reference the manufacturer designation between MACOM and Aeroflex if sourcing from legacy channels.
Selection Notes
Select this component when a compact, voltage-variable attenuator is required for frequencies up to 1 GHz. The integration of the hybrid coupler simplifies circuit design compared to discrete PIN diode implementations. Consider the 8-SOIC package size for space-constrained layouts. Verify that the control voltage requirements align with your system's drive capabilities.
Part Context
This part belongs to the MACOM MA4VAT series of voltage-variable attenuators. These devices are engineered for RF and IF applications where adjustable signal attenuation is necessary. The series typically employs HMIC technology for reliability and performance consistency across temperature variations.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult MACOM Technology Solutions or authorized distributors for current equivalent recommendations based on updated product lines.
