Description:
750 - 3000 MHz RF source
subassembly. The design consists of: Fractional N PLL,
discrete VCO, Dividers, RF harmonic filters, precision AGC
leveling loop, and output amplifiers. The 6 layer PCB was
designed with Coplanar waveguide over groundplane and
Stripline techniques for very low sensitivity to
manufacturing tolerances and very low assembly costs.
