This high-performance RF downconverter C-band LNB 5.25-6.3 WR-159 N/F/SMA operates in the 5.25-6.3 GHz frequency range and converts signals to a lower IF band of 0.95-2.0 GHz. Featuring a stable 4.3 GHz local oscillator with ±1 ppm accuracy and exceptionally low phase noise (up to -104 dBc/Hz), it ensures precise signal processing in demanding microwave communication systems.
With a noise figure as low as 1.9 dB and a minimum gain of 46 dB, this unit provides exceptional signal amplification and clarity. The integrated AGC (Automatic Gain Control) maintains consistent output power between -1 dBm and +1 dBm, while mirror channel suppression exceeds 45 dB.
L.O.: 4.3 GHz IN freq.: 5.25–6.3 GHz OUT freq.: 950 – 2000 MHz
