SKY13526-485LF

SKY13526-485LF is a broadband RF switch from Skyworks (lead‑free = LF) used to route RF signals in front‑end modules. It is an RF switch (typically SPDT) with a common port and two selectable RF paths, controlled by a logic/control input and a supply.
Key points:
- Function: switches RF between two output paths for a common input, enabling antenna switching or path selection in multi‑band transceivers.
- Bandwidth: designed for wide RF coverage suitable for cellular, Wi‑Fi, and other wireless bands (broadband, multi‑GHz operation).
- Performance: aims for low insertion loss and high isolation between ports, with low control power and good linearity.
- Package: compact lead‑free package suitable for integration in mobile and compact RF modules.
- Applications: smartphones/tablets, IoT devices, wireless routers, small base stations, and other RF front‑end applications.
Note: exact frequency range, pinout, biasing, and control logic are available in the official datasheet and application notes. If you’re designing a circuit, consult those documents for the precise specifications and recommendations.

SKY13526-485LF is a broadband RF switch (lead-free) from Skyworks. Key features commonly include:
- 50-ohm matched input/output
- Low insertion loss
- High isolation across the operating band
- Low-voltage, CMOS/TTL-compatible control
- Fast switching
- Integrated ESD protection
- RoHS-compliant, lead-free package
- Wide operating temperature range (typical -40°C to +85°C)
- Small, space-saving package suitable for mobile/RF front-end modules
Note: Please consult the official datasheet for exact specs (frequency range, insertion loss and isolation values, control voltage, switching time, and supply current) for your particular application.

Lead-free QFN package (16-pin, approximately 3×3 mm).

Pin count: 6 pins (SOT-23‑6 package).
Function: The SKY13526‑485LF is a voltage‑controlled single‑pole double‑throw (SPDT) RF switch. It routes an RF common port to one of two RF ports (e.g., antenna ↔ Tx or Rx paths) with low insertion loss and high isolation for front‑end switching in wireless applications; control logic pins select the active path and the package includes Vdd and ground.

Manufacturer: Skyworks Solutions, Inc.
What kind of company: Skyworks is a publicly traded semiconductor company (NASDAQ: SWKS) that designs and manufactures analog and mixed‑signal semiconductors—especially RF front‑end components (amplifiers, switches, tuners, power management)—for wireless communications (smartphones, Wi‑Fi/Bluetooth, IoT, automotive and infrastructure).

SKY13526-485LF is an RF switch used to route RF signals in 50-ohm front-end modules. Applications include mobile handsets/tablets, IoT devices, WLAN/Bluetooth front-ends, LTE/5G transceivers, RF test gear, and automotive/industrial wireless modules. It enables switching between antennas and between PA/LNA and filters in RF paths.
