Product Descriptions

The SKY66421-11 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 frequency range.

The SKY66421-11 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 SKY66421-11 to be used in battery powered applications over a wide spectrum of the battery discharge curve. The SKY66421-11 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 SKY66421-11 is provided in Figure 1. Figure 2 shows the pinout for the SKY66421-11. Table 1 lists the pin assignments and signal descriptions.
