Description

The SKY66108-11 is a high-performance, fully integrated RF

Energy applications.

The SKY66108-11 is designed for ease of use and maximum

flexibility, with integrated fully matched input balun, integrated

inter-stage matching and harmonic filter, and digital controls that

are compatible with 1.6 V to 3.6 V Complementary Metal Oxide

Semiconductor (CMOS) levels.

The RF blocks operate over a wide supply voltage range from

2.0 V to 3.6V, which allows the SKY66108-11 to be used in

battery-powered applications over a wide spectrum of the battery

discharge curve.

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 descriptions are provided in

Table 1.
