Description
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.
Skyworks GreenTM products are compliant with
all applicable legislation and are halogen-free.
For additional information, refer to Skyworks
Definition of GreenTM, document number
SQ04–0074.
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. A functional block diagram is
shown in Figure 1. The pin configuration and package are shown
in Figure 2. Signal pin assignments and functional pin
descriptions are provided in Table 1.
