Technical Deep Dive
Radar-Optimized Signal Architecture
Features "High-Purity Microwave Core + Multi-Channel Modulation" design: Ultra-low phase noise synthesizer achieves -68dBc spurious performance at 20GHz (Source: Input description). Five independent function generators create complex AM/FM/ΦM/pulse modulation scenarios. High-power amplifier delivers +19dBm output to drive power amplifiers directly. 600μs switching enables rapid frequency hopping for electronic warfare simulation. Compact 2U form factor saves 50% rack space compared to traditional signal generators.
| Technical Dimension | MXG Signal Generator | Traditional PSG | Advantage |
|---|---|---|---|
| Form Factor | 2U compact design | 4U+ typical | Saves 50% rack space for field-deployable systems |
| Test Speed | 600μs parameter switching | 2-5ms typical | Reduces radar calibration time by 70% |
FMCW Radar Test Workflow
Connection: Connect MXG to radar module LO input, enable all 5 function generators
Configuration:
- Generator 1: Linear FM chirp (24-24.25GHz, 1ms duration)
- Generator 2: AM modulation (1kHz sine wave)
- Set output power: +15dBm at 24GHzTesting:
- Measure phase noise: <-80dBc/Hz at 100kHz offset
- Verify spurious emissions: <-65dBc across band
- Test switching: Validate 600μs frequency hop between chirpsAnalysis: Generate spectral purity report for radar certification
Power Output Limitation
Output power decreases to +12dBm at 40GHz (Based on microwave amplifier characteristics). Mitigation: ① Use external amplifiers for high-power mmWave requirements; ② Operate at ≤20GHz for maximum +19dBm performance.
