SKYWORKS SKYA21003

The SKYA21003 is a CMOS, silicon-on-insulator (SOI) single-pole, double-throw (SPDT) switch. The high linearity and low insertion loss of the SKYA21003 make it an ideal choice for WCDMA data card applications. The switch is a “reflective short” on the isolated port. The SKYA21003 SPDT switch is provided in a compact Quad Flat No-Lead (QFN) 2 x 2 mm package. The SKYA21003 is designed for medium to high power WCDMA data card switching applications. The device can also be used in a variety of other applications that require high performance RF switching such as WLANs (a/b/g/n). An internal negative voltage generator and decoder eliminate the need for external DC blocking capacitors on the RF ports unless VDC is externally applied. Switching is controlled by one voltage input (CTRL). Depending on the logic voltage level applied to the control pin, the RF1 pin is connected to one of two switched RF outputs (RF2 or RF3) using a low insertion loss path, while the path between the RF1 pin and the other RF output pin is in a high isolation state. An internal decoder is used to provide the correct logic to the switch. Shutdown mode is enabled by connecting the ENABLE pin to logic low. Shutdown mode reduces the overall current consumption of the device to 7 μA, typical.
