SKY13526-485LF

SKY13526-485LF is a Skyworks RF switch IC in a lead-free package. It’s designed to route RF signals in front-end modules (mobile, IoT, and wireless systems) by switching between RF paths.
- Type: RF switch (used to connect a common port to one of multiple RF paths; suitable for SPDT configurations in many designs).
- Impedance: Typical 50 Ω match.
- Control: Bias/logic-level control with low power consumption; supports fast switching.
- Package: Small lead-free (LF) package suitable for compact assemblies.
- Applications: Antenna switching for transmit/receive paths, diversity switching, front-end modules, and RF routing in cellular/WLAN systems.
- Notes: For exact frequency coverage, pinout, biasing, and electrical specifications, consult the official Skyworks datasheet and application notes.

Here are the typical features of SKY13526-485LF (concise):
- Broadband SPDT RF switch with 50-ohm matched ports
- Low insertion loss and high isolation between ports
- Single-supply operation with a logic-level control input
- Low control current and fast switching
- Tiny lead-free package, RoHS-compliant, suitable for surface mounting
- ESD protection on RF and control pins
- Wide operating temperature range (commercial-grade: -40°C to +85°C)
- Applications: RF front-end switching in mobile devices, WLAN, GNSS, and similar front-ends
Note: Exact performance (loss, isolation, bandwidth, control voltage, and temperature range) is in the official datasheet.

- Pin count: 6 pins
- Function: RF SPDT (single-pole, double-throw) antenna switch. It has one common RF port and two throw ports; a control input selects which RF path is connected (lead-free package).

- Manufacturer: Skyworks Solutions, Inc. (Skyworks).
- What kind of company: An American fabless semiconductor company that designs and supplies RF/microwave front-end components (e.g., switches, amplifiers) for wireless communications; publicly traded on NASDAQ (SWKS).

Applications areas for SKY13526-485LF include:
- RF front-end switch for mobile devices (smartphones, tablets, IoT) to switch antennas across multiple cellular bands (2G/3G/4G/5G)
- GNSS receivers (GPS/GLONASS/Galileo) front-end switching
- Wireless infrastructure components (small cells, repeaters, base-FE modules)
- RF test and evaluation equipment and development kits
- Any 50-ohm system needing low insertion loss and high isolation in a compact package (antenna switching, path selection, redundancy)
