AFEM-S102-BLKG

RF Switches Overview

The AFEM-S102-BLKG is an RF switch IC designed for 802.11b/g/n applications, operating within a frequency range of 2.4GHz to 2.5GHz. It features a Single Pole Triple Throw (SP3T) circuit configuration with a 50-ohm impedance. Key electrical parameters include an insertion loss of 0.6dB at 2.4GHz, isolation of 27dB, P1dB of 31dBm, and IIP3 of 43dBm. The device operates on a 3V supply voltage and is housed in a 12-QFN (2.2x2.2) surface-mount package. It supports a working temperature range of -30°C to 85°C.

RF Switches Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking secondary market suppliers or legacy stock. Ensure compatibility with existing designs as new production is discontinued. Confirm package integrity and pinout alignment before integration into replacement systems.

RF Switches Selection Notes

Select this part for designs requiring SP3T switching in the 2.4GHz ISM band. Verify that the 12-QFN footprint matches the PCB layout constraints. Consider thermal management within the specified -30°C to 85°C range. Evaluate if the 3V supply voltage aligns with the system power rails.

RF Switches Part Context

The AFEM-S102-BLKG belongs to Broadcom's RF switch portfolio targeting WLAN infrastructure. It serves as a passive switching element rather than an active amplifier. The BLKG suffix typically denotes specific packaging or tape-and-reel configurations, though the core functionality remains consistent with the base AFEM-S102 model.

RF Switches Replacement Considerations

The AFEM-S102-TR1G is a documented alternative variant from the same manufacturer family. Verify pin compatibility and parameter equivalence before substitution. No other direct public substitutes are confirmed.
