概述

Description

SKY85310-21 is a Skyworks RF front-end module (FEM) used in mobile devices. It sits between the transceiver and the antenna and provides RF switching and impedance matching to support multi-band operation. The exact variant may include TX/RX switches, and sometimes limiters or other front-end components, all in a compact package designed for smartphones and similar wireless terminals.
Key points:
- Purpose: route and match RF signals between baseband and antenna across supported bands
- Packaging: small surface-mount FEM (typical 3x3 mm or similar)
- Features (variant dependent): TX/RX switching, high isolation, low insertion loss, ESD protection
- Applications: LTE/3G/2G mobile devices, tablets, IoT terminals
Design notes:
- Use the manufacturer’s reference design and pinout from the datasheet
- Follow recommended routing and filtering to minimize parasitics

Package

QFN, 16-pin package (2.0 × 3.0 mm).

Pinout

Pin count: 21 pins.
Function: SKY85310-21 is an RF front-end switch module (antenna/signal path switch) used in wireless transceivers. It provides an RF switching element with bias/control pins to route the RF signal among ports (e.g., for TX/RX or antenna path selection) and includes the necessary biasing network.

Manufacturer

Manufacturer: Skyworks Solutions, Inc.
Skyworks is an American semiconductor company (headquartered in Irvine, CA) that designs and supplies analog and mixed‑signal RF components—especially RF front‑end modules, power amplifiers, switches, filters and ICs—for mobile and wireless communications and broadband connectivity.

Application

SKY85310-21 is an RF front‑end module. Typical application areas include:
- Mobile devices (cellphones, tablets)
- IoT modules (sensors, wearables, smart home)
- Wireless gateways/routers
- Automotive telematics/infotainment
- Industrial wireless equipment
It is used in wireless transceiver systems requiring integrated RF front‑end functionality.
