How to put Pin Diode in CST

hello

I am doing research to put switch on CST

I put Microstrip line (MSL) as a switch

switch one put Microstrip line (MSL) as swith
switch off remove Microstrip line (MSL) as swith

How to do this using Pin Diode
what is suitable pin diode for this

I see this
SKY16601-555LF: Integrated Single-Stage PIN Diode Limiter Module 0.50 to 6.0 GHz

note my operating frequency is 2.6 GHz
