Hi.  I would like to know whether ADF4159 (with ramp generation capability)  could be used with ADF4351 (as a wideband VCO)?  I want to design a programmable LFM generator, and ADF4159 seems to be suitable.    I want to use ADF4351 as a wideband VCO with tuning voltage from 0 to 3V.  Is it possible to get LFM signal at the ADF4351 output. Specifically,  my requirement is:


Output Frequency:  1550 to 1600MHz

Ramp:  50MHz over 20us. (positive sweep)
