SST12LF02-QXCE

Product Overview

SST12LF02-QXCE from Microchip Technology is a 2.4 GHz WLAN power amplifier / RF front-end IC used in RF front-end designs that need integrated transmit, receive, switching or low-noise signal-chain functions. This description focuses on practical RF parameters such as band coverage, PA/LNA path behavior, control requirements and package compatibility.

The exact orderable suffix should be matched before purchase because RF front-end devices often vary by band plan, pinout, reel format, qualification grade and control-state truth table.

Key Features

• Manufacturer: Microchip Technology
• Part Number: SST12LF02-QXCE
• Device Type: 2.4 GHz WLAN power amplifier / RF front-end IC
• RF Band / Frequency Range: 2.4 GHz ISM / WLAN band
• Transmit / PA Path: Integrated 802.11b/g/n PA path with high linearity for WLAN transmitter chains
• Receive / LNA Path: Receive path is external or bypassed depending on SST11/SST12 device; not a complete LNA+PA FEM in every suffix
• Output Power / Linearity: Designed for WLAN output-power/EVM requirements; PA gain and output power are suffix-specific
• Control / Bias: Enable and bias-control pins for PA operation
• System Impedance: 50 Ω RF interface where specified by the device reference design or data sheet
• Package / Case: Small QFN package family
• Operating Temperature: RF front-end module temperature range is suffix-specific; verify industrial or automotive grade before sourcing
• Design Notes: Use SST11/SST12 as a PA/front-end match only after checking exact gain, output power and package pinout.

Applications

2.4 GHz WLAN modules, embedded Wi-Fi transmitters and legacy Microchip/SST RF front-end designs.

Also suitable for engineering replacements, shortage support and BOM consolidation where the same RF band, package footprint and control interface must be maintained.

Quality & Sourcing

Antrex Electronics can support sourcing for SST12LF02-QXCE through available stock checks, BOM consolidation and alternative-lot review. For RF front-end modules, packaging condition, date code, MSL handling, reel labeling and moisture exposure should be checked before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers reduce risk when sourcing hard-to-find or lifecycle-sensitive RF front-end components.
