300 kHz-6.0 GHz SPDT Switch

The SKY13374-397LF is a CMOS Silicon-on-Insulator (SOI) single-pole, double-throw (SPDT) WCDMA band switch. The high linearity performance and low insertion loss achieved by the device makes it an ideal choice for medium to high power WCDMA handset and data card applications.

The high 0.1 dB Input Compression Point (IP0.1dB) and advance proprietary fabrication process enable exceptional WCDMA harmonic and Adjacent Channel Power (ACP) performance. Excellent insertion loss and isolation is maintained over WCDMA bands 1 to 6 and 8 to 11.

The SKY13374-397LF SPDT switch is provided in a compact Quad Flat No-Lead (QFN) 2 x 2 mm package with 0.5 mm lead pitch for ease of manufacturing.
