ADL5374
Figure 36 shows the uncompensated error-vector magnitude
(EVM) vs. output power for a 10 MHz 1024-OFDMA waveform
at 3500 MHz.
LO GENERATION USING PLLS
Analog Devices has a line of PLLs that can be used for generating
the LO signal. Table 4 lists the PLLs together with their maximum
frequency and phase noise performance.

The
frequency ranges. One can be chosen depending on the local
oscillator frequency required. While the use of the integrated
synthesizer may come at the expense of slightly degraded noise
performance from the ADL5374, it can be a cheaper alternative
to a separate PLL and VCO solution. Table 5 shows the options
available.

TRANSMIT DAC OPTIONS
The
sheet is by no means the only DAC that can be used to drive the
ADL5374. There are other appropriate DACs, depending on the
level of performance required. Table 6 lists the dual TxDACs
offered by Analog Devices.

All DACs listed have nominal bias levels of 0.5 V and use the
same simple DAC modulator interface that is shown in Figure 32.
