AC ELECTRICAL CHARACTERISTICS—Rx Mode

RF pins using the typical applications and registers set to default settings and corresponding test mode, unless otherwise noted.

Unmodulated single-tone RF input signal is used with specifications that normally apply over the entire operating conditions, unless

otherwise indicated. RF inputs/outputs specifications are referenced to device pins and do not include 1dB loss from EV kit PCB,

balun, and SMA connectors.) (Note 1)
