Datasheet of the HMC980lp4e show example circuit for biasing of the amplifier and I want to use HMC980 to bias hmc 637 amplifier. According to example circuits drain voltage ports which is ports 18 and 19 directly connect to biasing circuit of the amplifier .My question is sholu I put series resistor and shunt capacitor between drain port of the HMC980 and biasing circuit of HMC637. If I should use what is the recommended values of resistor and capacitor

 

Thanks in advance
