FAQ
Q: What is the purpose of the RS485 port on the Limiting Amplifier?
A: The RS485 port enables real-time status reporting (e.g., module fault, gain level) and remote control (e.g., enabling/disabling the limiter). We provide a standard communication protocol manual to facilitate integration with your system's control platform.
Q: Are the products compatible with outdoor environments?
A: Yes, both products have an operating temperature range of -40℃~+60℃ and use corrosion-resistant materials (stainless steel interfaces, aluminum alloy enclosures). For extreme humidity (≥95%), we offer optional IP67 waterproof enclosures.
Q: How does the Ka-Band Amplifier-Attenuator ensure channel isolation of 50dB?
A: We use high-isolation internal filters and shielded compartments between channels, minimizing crosstalk. The design is verified via EMI testing to ensure 50dB isolation across the full operating band.
Q: Can the Limiting Amplifier's limiter level be adjusted from 10dBm?
A: Yes, the limiter level can be customized to 5dBm~15dBm by replacing the internal limiting diode. This adjustment does not affect the amplifier's noise figure or gain.
Q: What power supply is required for the Ka-Band Amplifier-Attenuator?
A: It uses a standard AC 220V power supply (via Y50DX-1204ZJ10 connector). For DC-powered systems, we offer a optional AC-DC converter module (input: 12~28V DC, output: 220V AC).
Q: How long does it take to resolve a field fault?
A: For minor issues (e.g., parameter misconfiguration), our engineers can provide remote troubleshooting within 4 hours. For hardware faults, we offer a "swap-out" service: send a replacement unit within 3 business days, and repair the faulty unit upon receipt.
Q: Are the products compatible with third-party RF components (e.g., filters, mixers)?
A: Yes, all products have 50Ω impedance matching, which is standard for RF systems. We can also test compatibility with your specific third-party components upon request.
Q: What is the maximum cable length between the Ka-Band Amplifier-Attenuator and downstream components?
A: For Ka-band signals (18.95~21.25GHz), we recommend ≤3m (using low-loss coaxial cable, e.g., RG-405) to minimize signal attenuation. We can provide custom low-loss cables as part of the solution.
