DC ELECTRICAL CHARACTERISTICS (continued)
(MAX2831 EV kit: V
high, RXHP = SCLK = DIN = low, RSSI and clock output buffer are off, no signal at RF inputs, all RF inputs and outputs terminated
into 50Ω, receiver baseband outputs are open. 100mV
baseband inputs of transmitter in transmit mode, f
mode, unless otherwise noted. Typical values are at V
otherwise noted. 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)
AC ELECTRICAL CHARACTERISTICS—Rx Mode
(MAX2831 EV kit: V
puts at 112 mV
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 which 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)
