Wi-Fi switches require less control signals

Two Wi-Fi switches from Skyworks are suitable for WLANs, repeaters, ISM band radios, Bluetooth systems, smartphones, and connectivity modules.

The SKY13585-679LF is a single-pole, double-throw (SPDT) switch intended for 1.0 to 6.0GHz applications. Advanced switching technologies maintain low insertion loss and high isolation for all switching paths, says the company.

The SKY13586-678LF is a single-pole, triple-throw (SP3T) antenna switch for 2.4GHz Wi-Fi applications. It offers a supply range of 3.0 to 5.0V and is compatible with 1.8 or 3.3V control logic.

According to the company, both switches require fewer control signals from industry-standard SP2T and SP3T switches. They also include integrated DC blocking capacitors, so no external DC blocking capacitors are required.

High-linearity performance and low insertion loss make them suitable for transmit/receive applications.

The switches are available in miniature 1.0 x 1.0mm and 1.1 x 1.1mm packages (six or eight pin) to save both board space and cost, says the company.
