Regarding trace impedance matching

Hello sir,

I am using voltage-controlled oscillator HMC431. In the datasheet of this VCO, it is mentioned that we need to maintain a 50-ohm trace impedance at the RFOUT pin. On the RFOUT pin, I have connected lumped components as shown in the figure. These lumped components are changing the impedance. So, how shall I maintain 50-ohm impedance at RFOUT pin?
