This professional-grade C-band dual LNB supports two distinct input bands: 3.4–4.2 GHz (LO: 5.15 GHz, IF: 0.95–1.75 GHz) and 4.5–4.8 GHz (LO: 5.95 GHz, IF: 1.15–1.45 GHz). With a conversion gain of 60 dB (typical), image rejection ≥40 dBc, and ultra-low phase noise (–95 dBc/Hz @100 kHz), it’s ideal for demanding satellite reception, Earth stations, and measurement systems.
Technical Highlights:
– Gain flatness ≤5 dBp-p; ripple ≤1 dBp-p over 36 MHz
– LO stability: internal ±5…25 kHz; external 10 MHz (–5…+5 dBm)
– Input VSWR ≤3.0; Output VSWR ≤2.5
– Input: CPR229G (WR‑229 with groove); Output: N/F/SMA (female)
– Power: +12…+24 VDC per band; ≤250 mA each
– Rugged aluminum body, IP67 rated, operates –40 °C to +60 °C
– Dimensions: 98.8×70.0×165.0 mm; Weight: 780 g
Backed by our lab-tested quality, 1.5-year warranty, and 7 years of extended service. For professional integrators and ground station operators.
