This S-band Low‑Noise Block Downconverter is built for input frequencies from 2.7 to 3.1 GHz and downconverts to 0.95 to 1.35 GHz using a highly stable 4.05 GHz LO. With gain ≥50 dB and phase noise as low as –65 dBc/Hz @1 kHz and –80 dBc/Hz @10 kHz, this LNB meets the strict requirements of advanced telecom, defense, and test applications.
Highlights:
– Input VSWR: ≤1.8
– I/O Impedance: 50 Ω (SMA/N-type) or 75 Ω (F-type)
– Mirror rejection ≥40 dB
– AGC range ≥25 dB
– Gain flatness: ±2.0 dB full band, ≤0.5 dB over 30 MHz
– Power: +12–24 VDC, ≤350 mA
– Operating temperature: –30…+60 °C; humidity up to 95 %
Supported by 1.5-year warranty and 7-year extended support. Lab-developed, field-proven.
