Model:AM-UVS23

AM-UVS23 Ku Band PLL LNB – Technical Specifications

Key Advantages

1. PLL Locking Technology

   • Eliminates frequency drift caused by temperature variations (critical in extreme climates).
   • Ultra-low phase noise, ideal for digital signals (DVB-S2X, 4K) and high-speed data (QPSK/8PSK in VSAT).

2. Ultra-Low Noise Figure (0.6 dB)

   • Near-theoretical noise performance, enhancing weak-signal reception (e.g., small-dish antennas or rain-fade scenarios).

3. Dual LO Design (9.75/10.6 GHz)

   • Automatically covers the full Ku band (10.7–12.75 GHz) without manual LO switching.

Working Principle

1. Signal Reception : Satellite antenna captures Ku-band signals.
2. Downconversion : PLL-controlled LO mixes the signal to IF (950–2150 MHz).
3. Amplification : Low-Noise Amplifier (LNA) boosts weak signals.
4. Output : IF signal transmitted via coaxial cable to the receiver.

PLL LNB vs. Traditional LNB

Applications

• Direct-to-Home (DTH) TV (e.g., Astra 28.2°E, Hotbird 13°E).
• VSAT Communications (requires stable LO for high-order modulations).
• Military/Maritime Links (reliability in harsh environments).
• 4K/8K UHD Broadcast (low phase noise ensures error-free decoding).

Installation Notes

• Align the antenna precisely (use a signal meter).
• Configure receiver settings: Universal PLL LNB , LO frequencies (9.75/10.6 GHz), and DiSEqC polarization control.
