SKYA21037 Block Diagram Broadband frequency range: 0.7 to 3.8 GHz Ultra-low insertion loss: 0.5 dB 2.7 GHz Description GSM power handling The SKYA21037 is a state-of-the-art CMOS, silicon-on- Single control voltage input insulator (SOI) double-pole, double-throw (DPDT) switch. The No DC blocking capacitors required switch provides high-linearity performance, low insertion loss, Lead (Pb)-free and RoHS-compliant, low profile QFN (12-pin, and high isolation. 2 2 mm) package (MSL1, 260 C per JEDEC J-STD-020) Switching is controlled by one voltage input (CTRL1). Depending on the logic voltage level applied to this pin, the PORT1 and PORT2 pins connect to one of the two other RF port pins (PORT3 TM Skyworks Green products are compliant with or PORT4) through a low insertion loss path, while maintaining a all applicable legislation and are halogen-free. high-isolation path to the alternate port. No external DC blocking For additional information, refer to Skyworks capacitors are required on the RF path as long as no DC voltage is TM Denition of Green , document number applied externally. SQ040074. The SKYA21037 DPDT switch is provided in a low profile Quad Flat No-Lead (QFN) 2 x 2 mm package. A functional block diagram is shown in Figure 1. Skyworks Solutions, Inc.
