Skyworks releases switches for automotive and comms
Automotive switches and low-noise amplifier front-end modules from Skyworks are designed for automotive, cellular compensator and cellular telematics applications.
The company has released four devices, the SKYA21038, SKYA21039, SKYA210140 and SKYA21041.
The SKYA21038 is a single pole, double throw (SPDT) switch intended for mode switching in WLAN applications. Switching technologies enable the SKYA21038 to maintain a low insertion loss and high isolation for all switching paths, says Skyworks. The high-linearity performance and low insertion loss mean that the switch is suitable for low power transmit / receive applications.
The switch is manufactured in a compact, 1.0 x 1.0 x 0.5mm, six-pin exposed pad plastic micro leadframe package dual (MLPD) package.
The SKYA21039 is a single pole, triple throw (SP3T) antenna switch that operates in the 2.4 to 2.5GHz frequency range. Switching between the antenna (RFC signal) and the RF1, RF2, and RF3 ports is accomplished with two control voltages (V1 and V2). Characteristics of low loss, high isolation, high linearity, small size, and low cost make the switch suitable for all WLAN and Bluetooth systems operating in the 2.4 to 2.5GHz band. The SKYA21039 is manufactured in a compact, 1.1 x 1.1 x 0.5mm, eight-pin Micro Leadframe (MLP) package.
The SKYA21040 integrates a single pole, triple throw (SP3T) switch and low noise amplifier (LNA) with a bypass mode in a compact package. The device is capable of switching between WLAN receive, WLAN transmit, and Bluetooth and is provided in a small dual flat no-lead (DFN) eight-pin, 1.5 x 1.5mm package.
The fourth switch is the SKYA21041 which integrates a single pole, double throw (SPDT) switch and low noise amplifier (LNA) with a bypass mode in a six-pin, 1.2 x 1.4mm DFN package. It is capable of switching between WLAN receive and WLAN transmit.
