Measure Transducer Gain of Device Under Test

Open Script

Use the Transducer Gain Testbench block to verify the gain of a device under test (DUT).

Connect the blocks as shown in the model.

Set the parameters for DUT and the testbench.

Amplifier block:

  • Available power gain — 10 dB

Mixer block:

  • Available power gain — 5 dB

  • Local oscillator frequency — 1.9 GHz

Transducer Gain Testbench:

  • Input frequency (Hz) — 0.1e9

  • Output frequency (Hz) — 2.0e9

Run the model. You will see that the display shows a transducer gain value of 15 dB. This can be calculated using the equation, Transducer gain of the DUT = Available power gain of Amplifier + Available power gain of Mixer = 10 dB + 5 dB = 15 dB.
