Skyworks Solutions Inc of Woburn, MA, USA (which manufactures analog and mixed-signal semiconductors) has launched two new Wi-Fi switches suitable for WLAN networks, repeaters, ISM-band radios, Bluetooth systems, smartphones, and connectivity modules.
The SKY13585-679LF is a single-pole double-throw (SPDT) switch intended for 1-6GHz applications, maintaining low insertion loss and high isolation for all switching paths. The SKY13586-678LF is a single-pole triple-throw (SP3T) antenna switch for 2.4GHz Wi-Fi applications.
The new devices offer wide 3-5V supply range and are compatible with 1.8V or 3.3V control logic. They require fewer control signals from industry-standard SP2T and SP3T solutions and include integrated DC blocking capacitors, so no external DC blocking capacitors are required. They also feature what is said to be high-linearity performance and low insertion loss, making them suitable for transmit/receive applications.
The switches are available in ultra-miniature 1x1 and 1.1 x 1.1 packages (6-or 8-pin), saving application board space and cost for OEMs.
