LNA output to Mixer Matching

Hi,

Do we need to match the LNA output impedence to the input of the mixer? (I am using a multiplying type mixer. The output of the LNA feeds the gate of mixer transistor.)

if ur talking about integrated LNA and mixer , u donot need matching if the length between them short enough
