Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13492-21 are provided
in Table 2. Electrical specifications are provided in Tables 3 and 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 shows a timing diagram. Figure 4 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 the TRX1 through TRX14 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 SKY13492-21 exhibits
exceptional performance for all TRXx ports.
Table 8 shows the isolation matrix for "On" to "Off" arms. Table 9
shows the isolation matrix for "Ant” to "Off" arms. Table 10
provides the matrix of insertion loss and return loss information.
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.
Figures 5 and 6 provide the timing diagrams for register write
commands and read commands, respectively.
Table 12 provides the Register_0 logic. Table 13 describes the
register parameters and bit values.
