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 ADF4360x comes as a family of chips, with nine operating

frequency ranges. One can be chosen depending on the local

oscillator frequency required. While the use of the integrated

synthesizer might come at the expense of slightly degraded

noise performance from the ADL5385, it can be a cheaper

alternative to a separate PLL and VCO solution. Alternatively,

the ADF4351 can be used, which covers a frequency range of

35 MHz to 4400 MHz. Table 5 shows the options available.

Data Sheet

TRANSMIT DAC OPTIONS

The AD9777 recommended in the previous sections is by no

means the only DAC that can be used to drive the ADL5385.

There are other appropriate DACs depending on the level of

performance required. Table 6 lists the dual TxDACs that

Analog Devices offers.

All DACs listed have nominal bias levels of 0.5 V and use the

same DAC-modulator interface shown in Figure 33.
