LNB-Ka420DN Ka-Band Uplink Dual-LO LNB
Features:
■ Uplink of Ka bandCovers 27.5–29.5 GHz and 29.0–31.0 GHz using two selectable LO frequencies for wide Ka-band operation.
■ Low noise down-converterProvides a 3.9 dB noise figure and ≥55 dB gain for stable receive-chain performance.
■ Uses 13 V / 18 V supply control to select the 26.55 GHz or 28.05 GHz LO.
■ Customized in frequency or gainAvailable with WR-28 waveguide input or 2.92 mm coaxial input to match different RF interfaces.
