PRODUCTION DATA.
Although the majority of devices have a VCO range of 7.5 to 15 GHz, this is NOT ensured. In reality, the VCO is tested for sure to cover 7.7 to 15 GHz. In the range of 7.5 to 7.7 GHz and 15 to 15.4 GHz, the VCO will cover at least enough frequency to cover a factor of two in frequency. What this means if using the internal mixer is that if one wants a LO frequency of 7.6 GHz, then first try this using the poly mode and VCO frequency of 7.6 GHz. However, if the VCO can not do 7.6 GHz, then one has to try DIV2 Mode with the VCO at 15.2 GHz.
