Note 1:
Parameters are production tested at +25
°
C only. Min/max limits over temperature are guaranteed by design and charac-
terization.
Defined as the baseband differential RMS output voltage divided by the RMS input voltage (at the RF balun input).
Noise-figure specification excludes the loss of the external balun. The external balun loss is typically ~0.5dB.
CCK interferer at 25MHz offset. Desired signal equals -73dBm. Interferer amplitude increases until baseband output from
interferer is 10dB below desired signal. Adjacent channel rejection = P
interferer
- P
desired
.
Measured at balun input. Two CW tones at -43dBm with 15MHz and 25MHz spacing from the MAX2820/MAX2821 channel
frequency. IP3 is computed from 5MHz IMD3 product measured at the RX I/Q output.
Two CW interferers at -38dBm with 24.5MHz and 25.5MHz spacing from the MAX2820/MAX2821 channel frequency. IP2 is
computed from the 1MHz IMD2 product measured at the RX I/Q output.
Output power measured after the matching and balun. TX gain is set to maximum.
Adjacent and alternate channel power relative to the desired signal. TX gain is adjusted until the output power is -1dBm.
Power measured with 100kHz video BW and 100kHz resolution BW.
Time required to reprogram the PLL, change the operating channel, and wait for the operating channel center frequency to
settle within
±
10kHz of the nominal (final) channel frequency.
Note 10:
Relative amplitude of reference spurious products appearing in the TX RF output spectrum relative to a CW tone at
0.5MHz offset from the LO.
Note 11:
Min/max limits are guaranteed by design and characterization.
