SkyWorks' Power RF switches for TD-LTE infra and mil/microwave UHF and UVF radios

Skyworks Solutions has introduced a new line of high power RF switches – up to 100 Watts – supporting diverse market applications including TD-LTE infrastructure base stations, repeaters and low frequency military/microwave UHF and UVF radios.

“Skyworks is delighted to be offering customers unique and innovative products for their demanding RF design needs,” said David Stasey, vice president of Analog Components at Skyworks. “By replacing expensive mechanical switches and complicated relays, our newest devices simplify architectures for applications with challenging power levels. With design wins at several tier one customers, Skyworks continues to leverage its broad technical leadership and scale across multiple and diverse markets.”

The SKY12207-478LF (0.9 – 4.0 GHz), SKY12208-306LF (0.02 – 2.7 GHz) and SKY12210-478LF (0.9 – 4.0 GHz) are high power SPDT silicon-based PIN diode switches. The 4 x 4 millimeter, 16-pin quad flat no lead packaged devices features low insertion loss (0.4dB), high isolation (44 dB), excellent power handling (50 and 100 Watts) and superb linearity with low direct current (DC) power consumption. They all operate with a 5 or 28 V positive DC voltage supply across a broad frequency range (20 MHz – 4.0 GHz). Skyworks has also developed a complementary driver application circuit to align with these switches.

Skyworks’ new switches are currently available.
