RF Output Spectrum
The following figures represent spectrums of the transmitter carrier, measured in conduction mode. Three different spans have
been used. The 5 MHz span spectrum ( Figure 5 ) shows phase noise response close to the RF carrier and the noise suppression
within the PLL-loop bandwidth. The 50 MHz span spectrum ( Figure 6 ) shows phase noise and reference spurious. Finally, the
1.5 GHz span spectrum ( Figure 7 ) shows the second and third harmonics of carrier. All spectrums are measured in OOK
modulation at DATA=1.
Figure 8 shows the spectrum in case of FSK modulation with 45 kHz deviation at 4 kbit/s data rate.
