SI4831-B30-GUR

RF Receivers Overview

The SI4831-B30-GUR is an active RF receiver manufactured by Skyworks Solutions Inc., designed for AM and FM signal reception. It operates within a frequency range of 504kHz to 1.75MHz for AM and 64MHz to 109MHz for FM, supporting worldwide band configurations. The device functions on a supply voltage of 2V to 3.6V with a receive current of 21.5mA. It utilizes a 24-SSOP surface-mount package and supports operation across a temperature range of -40°C to 95°C.

RF Receivers Feature Summary

• Supports worldwide FM band coverage from 64MHz to 109MHz
• Provides AM band support ranging from 504kHz to 1.75MHz
• Integrates mechanical tuning capabilities with stereo output functionality

RF Receivers Applications

• General purpose radio receivers
• AM/FM broadcast reception systems
• Portable audio devices requiring low power consumption

RF Receivers Procurement Notes

Verify the specific suffix GUR indicates tape and reel packaging when ordering. Confirm that the B30 variant aligns with required worldwide FM and AM band specifications rather than regional variants. Ensure design compatibility with the 24-SSOP footprint and 2V to 3.6V supply requirements before procurement.

RF Receivers Selection Notes

Select this component for applications requiring integrated AM and FM reception in a compact surface-mount form factor. Consider the 21.5mA operating current for battery life calculations. Verify that the 24-SSOP package dimensions fit the target PCB layout constraints and that the -40°C to 95°C temperature range meets environmental operational needs.

RF Receivers Part Context

This part belongs to the SI4831 series of single-chip AM/FM radio receivers. It is distinct from the SI4835 which includes shortwave support. The B30 designation specifies the frequency band configuration and feature set, while the GUR suffix denotes the specific packaging type for automated assembly processes.

RF Receivers Replacement Considerations

The SI4831-B31-GUR is a related variant offering similar functionality but with different operating temperature ranges and packaging options. Verify thermal requirements and supply chain availability when considering substitutes within the same product family.
