We present two microwave photonic RF comb generators based on a quartz-stabilized, ultra-low phase noise fs-pulse laser in combination with high-speed RF waveguide coupled photodetectors. With 325 GHz, the cutoff frequency of the subsystem exceeds the state of the art and enables broadband microwave comb generation with 1 GHz spacing in the D- and J-band, while obtaining spectrally pure single microwave tones with a spectral width below 1.5 Hz and high temporal stability.
