Ku-band PLL LNB

Low-noise block downconverter for 10.7–12.75 GHz with PLL LO and external 10 MHz reference.

TESART Ku-band PLL LNB, outdoor unit

Key features

Dual-band coverage: 10.70–11.75 GHz (low) and 11.75–12.75 GHz (high) — the full Ku downlink band

PLL local oscillator locked to an external 10 MHz reference, with an internal-reference option

Noise figure 0.9 dB typical (≤ 1.2 dB guaranteed) across the band

IF output doubles as DC power and 10 MHz reference input on a single N-type connector

WR-75 waveguide RF input; F-type 75 Ω IF output available as an option

Compact outdoor housing, −40 °C to +60 °C operating range
