Products Features
Ka-Band Amplifier-Attenuator
| Flexible multi-channel signal management |
2-input/8-output architecture with 21±1.5dB coupling, enabling efficient signal splitting and distribution for multi-receiver systems |
| Precise gain adjustment |
+35~-15dB gain range with 1dB step adjustment, supporting fine-tuning of signal levels to match downstream component requirements |
| Intelligent memory & recovery | Saves network parameters and gain settings when powered off, and automatically restores them on power-up-reducing reconfiguration time for mission-critical systems. |
| Comprehensive fault detection | Monitors current of each internal module in real time, triggers alarms for abnormal conditions, and supports full-status query/response via remote control. |
| Dual-control modes | Allows local setting (via front-panel display) and remote control (for networked systems), enhancing operational flexibility. |
Limiting Amplifier
| Ultra-low noise & high gain |
Noise figure ≤1.8dB and gain 36±2dB, ensuring weak signal amplification without significant distortion-critical for radar and satellite signal reception. |
| Robust burn-in protection |
Withstands 3KW pulsed power (0.1% duty cycle) and 3W continuous wave, preventing device damage from sudden high-power interference (e.g., jamming signals). |
| Real-time status monitoring | Integrated monitoring circuit tracks the state of the amplification module, reports "normal/fault" status via RS485 serial port, and triggers alarms for timely troubleshooting. |
| Wide Limiter Frequency Coverage |
Limiter works across 1.3~15GHz, providing protection for the amplifier even when exposed to out-of-band high-power signals. |

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.
