Norsat 3120N C-Band LNB 3.7–4.2 GHz, ±5kHz, PLL, N-Type

Norsat 3120N C-Band LNB with Phase-Locked Loop (PLL) Oscillator and N-Type Connectors The Norsat 3120N is a professional C-Band Low-Noise Block (LNB) engineered for satellite communications, broadcast, and VSAT applications. Covering the C-Band input frequency range of 3.7–4.2 GHz, it delivers ±5 kHz frequency stability using precision PLL technology, ensuring minimal receiver drift and signal integrity over extended operation. **What is Phase-Locked Loop (PLL)?** A PLL is an oscillator circuit that locks to a reference frequency, maintaining precise frequency control. In LNBs, PLL technology eliminates drift caused by temperature fluctuations and aging, keeping your receiver locked to the correct satellite signal without manual adjustment—critical for professional installations requiring consistent performance. **N-Type Connector Purpose** N-Type connectors are professional-grade RF connectors designed for low-loss, secure connections in satellite and microwave systems. They provide superior shielding and durability compared to standard connectors, reducing signal loss and ensuring reliable long-term performance in outdoor installations. **Key Specifications:** - Input Frequency Range: 3.7–4.2 GHz (C-Band) - Frequency Stability: ±5 kHz - Connector: N-Type (male) - Phase Noise: Excellent (reduces bit-error rates) - Bit Rate: Up to 512 Kbps - Warranty: 3 Years **Ideal For:** Fixed satellite service (FSS), teleport operations, VSAT networks, and broadcast uplink/downlink stations. Perfect for system integrators and DIY installers upgrading existing C-Band receive systems where frequency stability and low noise performance are critical.
