I read few appnotes from Agilent, Hittite, Minicircuits, and all of them have such thing. Why not use the same capacitor value?
For example,
10GHz LNA: Cbypass=1000pF Cblock=1pF
Up to 12GHz prescaler: Cbypass=1000pF Cblock=100pF
MMIC amp around 10GHz: Cbypass=0.1uF=100000pF Cblock=0.001uF=1000pF
Some paper Cbypass=680pF Cblock=2pF
Why not choose something around 1pF for Cbypass at those freqs?
