NOTES: 1. Output of the LNA is matched to 230

Ω by inserting a 180 Ω resistor in series with its output port.

2. Output of the Mixer is matched to 1.5050 k

Ω by inserting a 1500 Ω resistor in series with its output port.

3. The circuit of this test board is the same as the schematic in Figure 2.
