Electrical and Mechanical Specifications
The absolute maximum ratings of the SKYA21054 are provided in
Table 2. Table 3 provides the recommended operating conditions.
Electrical specifications are provided in Table 4.
IMD2 and IMD3 test conditions for various frequencies are listed
in Tables 5 and 6, respectively.
Triple beat ratio (TBR) test conditions for bands 2 and 5 are listed
in Table 7.
Figure 3 illustrates the test setup used to measure
intermodulation products. This industry standardized test is used
to simulate the WCDMA Band 1 linearity of the antenna switch. A
+20 dBm continuous wave (CW) signal, fFUND, is sequentially
applied to all TRX ports, while a –15 dBm CW blocker signal, fBLK,
is applied to the ANT port.
The resulting third order intermodulation distortion (IMD3), fRX, is
measured over all phases of fFUND. The SKYA21054 exhibits
exceptional performance for all TRXx ports.
Figures 4 and 5 provide the timing diagrams for register write
commands and read commands, respectively.
Table 8 provides the insertion loss and return loss matrix. Table 9
shows the isolation matrix for ANT to OFF arms. Table 10 shows
the isolation matrix for ON to OFF arms.
Table 11 describes the register content and programming
read/write sequences. Refer to the MIPI Alliance Specification for
RF Front-End Control Interface (RFFE), v1.10 (26 July 2011) for
additional information on MIPI programming sequences and MIPI
bus specifications.
Table 12 provides the Register_0 logic.Table 13 describes the
register parameters and bit values.

1 _{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.
2 _{In all cases, ambient operating temperature (TA) is specified relative to case temperature (TC) and assumes TA = (TC – 10 °C). Case temperature (TC) refers to the temperature of the ground}
pad at the underside of the package.
ESD HANDLING: Although 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.
