SKYA21040

Product Overview

SKYA21040 is a single-pole three-throw (SP3T) RF switch IC from Skyworks Solutions Inc., intended for controlled signal routing in wireless front-end, broadband RF, instrumentation and embedded radio designs. The device helps select, isolate or redirect RF paths between antennas, filters, LNAs, PAs, receiver inputs, transmitter outputs or test nodes under electronic control.

The available product data indicates single-pole three-throw (SP3T) operation with up to 2.4 GHz RF operation in a 8-XFDFN package. In a practical RF design, engineers should review insertion loss, off-state isolation, return loss, RF power handling, switching speed, ESD rating and control-logic compatibility before approving SKYA21040 for production.

Key Features

• Manufacturer: Skyworks Solutions Inc.
• Part Number: SKYA21040
• Device Type: single-pole three-throw (SP3T) RF switch IC
• Switch Configuration: single-pole three-throw (SP3T)
• Frequency Range: up to 2.4 GHz
• System Impedance: 50 Ω RF signal-chain use is typical for this class of RF switch; confirm the exact impedance data in the datasheet
• Control / Actuation: Logic-controlled RF switch IC; control levels and bias pins should be matched to the Skyworks datasheet
• RF Path Style: RF path style should be confirmed as reflective or absorptive from the datasheet for the exact suffix
• Package / Case: 8-XFDFN
• PCB / Assembly Note: leadless SMT RF package requiring controlled-impedance layout and solid ground connection
• Product Description: single-pole three-throw (SP3T), for RF paths up to 2.4 GHz, in 8-XFDFN for antenna selection, front-end routing, filter-bank switching or test-path control
• Design Notes: Validate insertion loss, isolation, return loss, linearity, RF power rating, switching time, ESD rating and control truth table from the official manufacturer datasheet before production approval

Applications

SKYA21040 can be used in RF front-end modules, antenna-switching circuits, receiver/transmitter path selection, filter-bank routing, RF test interfaces, wireless communication equipment and compact radio boards. It is especially relevant where a controlled RF path must replace a mechanical jumper, relay contact or larger discrete switching arrangement.

For BOM continuation, repair or redesign projects, buyers should compare the exact switch configuration, frequency range, package or connector format, RF port arrangement and control method with the existing circuit. Substitution should only be approved after confirming the datasheet parameters and board-level RF layout requirements.

Quality & Sourcing

Antrex Electronics can support SKYA21040 sourcing with stock availability checks, RFQ quotation, date code review, package confirmation and shipment arrangement. For RF switch purchasing, buyers can provide target quantity, acceptable date code, packaging preference, required frequency range, switch topology and inspection requirements for faster quotation support.

For quality control, Antrex Electronics can help arrange product photos, label review, visual inspection and third-party testing support when required. OEMs, EMS providers, RF module manufacturers, repair teams and electronic component buyers are welcome to send BOM lists or hard-to-find RF switch requests for sourcing assistance.
