| Phase Noise Performance | ≤-110dBc/Hz @10kHz offset (1GHz) | ≤-95dBc/Hz typical | 15dB improvement for sensitive communication systems |
| Total Cost of Ownership | 3-year calibration + self-maintenance | 1-year calibration + factory service | Reduces operational costs by 40% over 5 years |
Power Amplifier Characterization Workflow
Connection: Connect generator to PA input, spectrum analyzer to output
Configuration:
- Set frequency: 3.5GHz (5G n78 band)
- Enable two-tone test: 3.500GHz + 3.501GHz
- Output power: +10dBm (drive PA to +30dBm output)Testing:
- Measure gain compression: P1dB point (>+28dBm)
- Calculate IMD3: <-30dBc at rated power
- Verify harmonic distortion: ≤-40dBc at 7GHzAnalysis: Generate AM/AM and AM/PM distortion plots
Frequency Limitation
Maximum 6GHz frequency (Based on input description). Mitigation: ① For mmWave applications, pair with external frequency multipliers; ② Use harmonic generation techniques for limited higher-frequency testing.
