Si1000/1/2/3/4/5
1.1. Typical Connection Diagram
The application shown in Figure 1.7 is designed for a system with a TX/RX direct-tie configuration without
the use of a TX/RX switch. Most lower power applications will use this configuration. A complete direct-tie
reference design is available from Silicon Laboratories applications support.
For applications seeking improved performance in the presence of multipath fading, antenna diversity can
be used. Antenna diversity support is integrated into the EZRadioPRO transceiver and can improve the
system link budget by 8–10 dB in the presence of these fading conditions, resulting in substantial range
increases. A complete Antenna Diversity reference design is available from Silicon Laboratories applica-
tions support.
