High-power attenuator:
b) 1dB compression point output power test steps:
Connect the instrument as shown in Figure 5-2, set the working frequency range of the signal source to
32GHz - 40GHz with the stepping by 0.5GHz, set the output power of the signal source connected to the
input port of the amplifier to -30dBm or any other value that can make the amplifier in the working state
of linear amplification, increase the output power of the signal source, record the reading on the power
meter when the gain is compressed by 1dB, then calculate the sum of this value and the attenuation value
on the attenuator, which is just the output power of the 1dB compression point.
(5) Non-harmonic Suppression Test
a) Testing equipment:
Signal source:
Spectrum analyzer:
High-power attenuator:
b) Testing diagram:
c) Non-harmonic suppression test steps:
Connect the instrument as shown in Figure 5-3, turn on the power of the signal source, the amplifier
1
and the spectrum analyzer preheating.
Set the operating range of the spectrum analyzer to 30GHz - 50GHz, set the initial operating
2
frequency of the signal source to 32GHz, with the stepping by 1GHz, adjust the amplifier to the 1dB
compression point output power state of each operating frequency point in turn according to the test
method of 1dB compression point for the output power of the amplifier, and record the difference
between the peak value of fundamental wave and the non-harmonic wave of the spectrum analyzer, which
should meet the indicator requirements at most operating frequency points.
