Description  



Independent BOM management to minimize PCN risk  



Broadband frequency support: 0.01 to 6.0 GHz  



Single bit control  

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.  



Rated for GSM power levels  

The switch is a “reflective short” on the isolated port.  



ESD: 1,500 V HBM Class 1C, 1,000 V CDM Class C3  



Low insertion loss: < +0.5 dBm at 2.5 GHz  



Excellent linearity: IMD3 < –105 dBm  



Designed and manufactured in ISO/TS16949 certified facility  

The SKYA21003 SPDT switch is provided in a compact Quad Flat  

No-Lead (QFN) 2 x 2 mm package. 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

Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set  

at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.  

ESD HANDLING

:

A

lthough this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.  

This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce  

potentials of several kilovolts on the human body or equipment, which can discharge without detection.  

Industry-standard ESD handling precautions should be used at all times.  

An internal decoder is used to provide the correct logic to the  

switch.  

Functional Description  

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).  

Shutdown mode is enabled by connecting the ENABLE pin to logic  

low. Shutdown mode reduces the overall current consumption of  

the device to 7

μ

A, typical.  

An internal negative voltage generator and decoder eliminate the  

need for external DC blocking capacitors on the RF ports unless  

VDC is externally applied.  

Electrical and Mechanical Specifications  

The absolute maximum ratings of the SKYA21003 are provided in  

Table 2. Electrical specifications are provided in Table 3.  

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.  

The state of the SKYA21003 is determined by the logic provided  

in Table 4.  

Typical performance characteristics of the SKYA21003 are  

illustrated in Figures 3 through 5.
