Engineered for the 3.05–3.45 GHz S-band range, this LNB features a precise 4.4 GHz LO for downconversion to 0.95–1.35 GHz. With high gain (≥50 dB), low phase noise (−65 dBc/Hz @1 kHz, −80 dBc/Hz @10 kHz), and AGC depth ≥25 dB, it’s ideal for telecom, satellite, military, and test system applications.
Key features:
– Input VSWR ≤1.8
– Mirror suppression ≥40 dB
– Gain flatness: ±2.0 dB across full band, ≤0.5 dB in 30 MHz segments
– SMA, N‑type, or F‑type I/O; impedance 50 Ω / 75 Ω
– Supply voltage: +12…+24 VDC
– Power consumption: ≤350 mA
– Operating temp: –30…+60 °C
– Storage: –40…+80 °C; humidity up to 95 %
Comes with a 1.5‑year warranty + 7‑year extended service. Contact us for integration guidance.
