We have requirement of generating Linear FMCW with the following requirements:
1) Carrier Frequency-7Ghz
3) Chirp type: Sawtooth or Triangular
4) Chirp time-8uS (16us-Triangular)
We are planning to use AD9910 DDS for generating Linear FMCW and up converting to 7Ghz using PLL HMC704 & VCO HMC505.
Could you please let us know Sawtooth/Triangular chirp is possible with time period of 8uS/16us in RAM mode and DRG mode using AD9910.
Also let us know what other DDS chipsets can be used to meet this requirement apart from AD9910.
