The SKY66420-11 is a high-performance, highly integrated RF
front-end module designed for high-power Industrial, Scientific,
Medical (ISM) band applications operating in the 860 to 930 MHz
The SKY66420-11 is designed for ease of use and maximum
flexibility with fully matched 50 TX (or TX_ALT) and RX inputs
and antenna outputs, and digital controls compatible with 1.6 to
3.6 V CMOS levels.
The RF blocks operate over a wide supply voltage range from 2.0
to 4.8 V allowing the SKY66420-11 to be used in battery powered
applications over a wide spectrum of the battery discharge curve.
The SKY66420-11 is packaged in a 16-pin, 3.0 x 3.0 x 0.75 mm
Multi-Chip Module (MCM) package.
A functional block diagram of the SKY66420-11 is provided in
Figure 1. Figure 2 shows the pinout for the SKY66420-11. Table 1
lists the pin assignments and signal descriptions.
