DPDT Diversity Switches

Skyworks has introduced two double-pole, double-throw (DPDT) high-performance, cost-effective diversity switches in industry standard packaging and footprint. The SKY13355-374LF is a low-power variant and the SKY13381-374LF is a higher P1 dB version for higher linearity applications (in the same pinout). The switches are ideal for wireless routers, printer modules, high power access points, and WLAN customer premise and infrastructure equipment given their pin-to-pin compatibility with high- and low-power devices.

SKY13355-374LF 0.1-6.0 GHz DPDT Switch
The SKY13355-374LF is a pHEMT GaAs Double-Pole, Double- Throw (DPDT) switch designed for 2.4 and 6.0 GHz, dual-band wireless LAN applications. The switch provides high linearity performance, low insertion loss, and high isolation in both frequency bands.

Switching is controlled by two voltage inputs (V1 and V2). Depending on the logic voltage level applied to the control pins, the ANT1 and ANT2 pins connect to one of two switched RF outputs (RX or TX) through a low insertion loss path while maintaining a high isolation path to the alternate port.

The switch is manufactured in a compact, 1.5 x 1.5 mm, 6-pin exposed pad plastic Micro Leadframe Package Dual (MLPD) package.

• Broadband frequency range: 0.1 to 6.0 GHz
• Positive control voltage range: 1.8 to 5.0 V
• Low insertion loss: 0.6 dB typical @ 2.5 GHz
• High isolation: 23.5 dB typical @ 2.5 GHz
• P1dB: +33 dBm typical @ 3 V
• Small, DFN (6-pin, 1.5 x 1.5 mm) Pb-free package (MSL1, 260 °C per JEDEC J-STD-020
