FAQ
Q: What is the difference between narrowband and broadband LNAs in your series?
A: Narrowband LNAs (e.g., C/Ku-band) are optimized for specific frequencies with lower NF (<1dB) and higher gain, while broadband models (1-18GHz) offer flexible multi-band coverage for SDR and 5G applications, with slightly higher typical NF (1.5dB) .
Q: Can your LNAs operate with unregulated power supplies?
A: Yes, all models include built-in voltage regulation (5-15V DC) and reverse-polarity protection. However, we recommend regulated supplies for optimal NF stability (<±0.1dB variation) .
Q: How does GaAs HEMT technology improve performance compared to silicon-based LNAs?
A: GaAs HEMTs have 5-8x higher electron mobility, enabling lower noise (NF reduced by 30-50%) and higher operating frequencies (up to 50GHz vs. 10GHz for silicon) - critical for satellite and radar applications .
Q: Do you offer redundant systems for mission-critical applications?
A: Yes, we provide 1+1 and 1+2 redundant LNA systems with automatic switchover (<5ms). These include a controller module, primary/backup units, and status monitoring via RS485 .
Q: What is the maximum cable length between the antenna and LNA?
A: For optimal performance, we recommend ≤10m for L-band (low loss) and ≤5m for Ka/Q-band (high-frequency loss). We can provide custom low-loss cables as part of the solution .
Q: How do I select the right LNA based on my system's noise budget?
A: Use Friis formula: Total NF ≈ LNA NF + (Subsequent NF - 1)/LNA Gain. Our engineers can calculate the required NF/gain for your system-contact us with your receiver's noise figure and cable loss .
Q: Can you modify the LNA for radiation-hardened applications (space use)?
A: Yes, our space-grade option uses radiation-hardened GaAs HEMTs and ceramic packaging, meeting MIL-STD-883G for total ionizing dose (TID) >100krad .
Q: Are your LNAs compatible with outdoor antenna mounts?
A: Yes, all models have IP67-rated enclosures and mounting flanges (NEMA standard), suitable for direct antenna integration. We also offer pole-mount kits for VSAT terminals .
