(1) Circuit and graph
Mixer Circuit
Input dBm versus frequency graph
LO dBm versus frequency graph
Mixer output dBm versus frequency graph

(2) Spec of design
P_nTone(Input) : Z=50ohm, P=polar(dbmtow(-25),0), Freq=1.1GHz
P_nTone(LO) : Z=50ohm, P=polar(dbmtow(-5),0), Freq=1GHz
Mixer : Sideband=Lower, Conversion Gain=dbpolar(-5), S11=polar(0,0), S22=polar(0,180), S33=0

(3) Answer
→ In the first experiment, We inputted signal which were 1.1GHz (-25dBm-size) into a mixer. And LO signal which were 1GHz (-5dBm-size) into a mixer as well. like above the circuit. And the mixer has -5dBm Gain. This gain value can be changed free by designer. If gain is negative value, then mixer seems like passive component. but If gain is positive value, then mixer seems like active component. As a result, simulation result graphs were produced like above graph.

Let's show the simulation result graph. The graph above is Output signal. We can check the signal that has amplitude of -30dBm at a 0.1GHz(=100MHz). I can notice the result is good result because the input-signal with -25dBm size enters mixer with -5dBm size. therefore we can see -25dBm(input power)-5dBm(mixer gain) = -30dBm(output power).
