AFE7684IABJ

Analog Front End (AFE) Overview

The AFE7684IABJ is a silicon-based RF front-end transceiver manufactured by Texas Instruments. It features a configuration of two transmit and four receive channels, operating within a frequency range up to 5.2 GHz. The device supports a maximum data rate of 1.5 Gbps and functions with supply voltages of -1.8 V, 1 V, 1.15 V, and 1.85 V. It is housed in an FCBGA-400 package suitable for SMD/SMT installation. The component operates reliably within a temperature range of -40°C to +85°C and exhibits humidity sensitivity.

Analog Front End (AFE) Procurement Notes

Verify the specific ordering suffix against the official Texas Instruments datasheet to ensure correct pinout and thermal specifications. Confirm RoHS compliance status through the manufacturer's documentation. Check for moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Analog Front End (AFE) Selection Notes

Select this component when a balanced multi-channel RF solution is required for frequencies up to 5.2 GHz. Ensure the design accommodates the FCBGA-400 package dimensions and thermal dissipation needs. Verify that the system power supplies align with the specified 1.15 V and 1.85 V requirements for optimal performance.

Analog Front End (AFE) Part Context

This part belongs to the AFE7684 series of RF front-ends from Texas Instruments. It is designed for high-performance wireless applications requiring integrated transmission and reception capabilities. The device complements other members of the family, such as the AFE7681, which offers different channel configurations.

Analog Front End (AFE) Replacement Considerations

The AFE7681IABJ serves as a related variant within the same product family, offering a 4-transmit and 2-receive configuration instead of the 2-TX/4-RX layout of the AFE7684IABJ. Both share similar packaging and operational characteristics.
