magnitude (EVM), spectral performance, and noise floor
(dBc/100 kHz at 6 MHz carrier offset) at 885 MHz and
1960 MHz. Based on spectral performance, a maximum output
power level of around 2 dBm is appropriate. Note, however, that
as the output power decreases below this level, there is only a
very slight increase in the dBc noise floor. This indicates that
baseband drive variation can be used to control or correct the
gain of the signal chain over a range of at least 5 dB, with little
or no SNR penalty.
performance, and noise floor at 885 MHz and 1960 MHz.
An LO drive level of approximately –6 dBm is recommended
for GMSK and 8-PSK. A higher LO drive power will improve
the noise floor slightly; however, it also tends to degrade EVM.
