SMW Q LNB 37.50-42.50 GHz Wideband

Description

SMW Q LNB 37.50 – 42.50 GHz Wideband PLL LNB The SMW Q LNB 37.50 – 42.50 GHz Wideband PLL LNB is an advanced Q-band downconverter designed for high-throughput SATCOM gateways, 5G backhaul, and next-generation Ka/Q/V applications. It covers 37.5-42.5 GHz in two sub-bands (37.5-40.0 GHz / 40.0-42.5 GHz) with ultra-low phase noise, external 10 MHz reference with internal fallback, RS-485 (Modbus RTU) monitoring & control, and automatic temperature-compensated gain-offering unmatched stability and performance for demanding networks. Input Frequency: 37.50 – 42.50 GHz (two models: 37.5-40.0 / 40.0-42.5 GHz) LO Frequencies: 36.55 GHz / 39.05 GHz IF Output: 950 – 3450 MHz (Wideband) Gain: 50 dB default (adjustable 40 – 55 dB via M&C) Gain Stability: ±0.1 dB / 24 h @ 23 °C; ±2 dB over temperature Noise Figure: typ. 2.8 dB / max. 3.6 dB @ 23 °C Phase Noise: -22 @ 1 Hz • -32 @ 10 Hz • -60 @ 100 Hz • -75 @ 1 kHz • -85 @ 10 kHz • -93 @ 100 kHz • -120 @ 1 MHz • -128 @ 10 MHz Image Rejection: ≥ 23 dB Flatness: ± 2 dB max Input VSWR: 2.3 : 1 max (no isolator required) Output VSWR: 1.7 : 1 max Output P1dB: ≥ +15 dBm Output IP3: ≥ +25 dBm Reference: External 10 MHz (-10 to +10 dBm) with fallback to internal ±35 ppm Input Connector: WR-22 waveguide (various flanges available) Output Connector: N-f (50 Ω) standard / SMA-f optional Power Supply: +11 – +26 V DC via output port (≤ 5 W) M&C Interface: RS-485 (Modbus RTU) with sum alarm (LNA fail, LO lock, voltage low, signal high/low etc.) Dimensions: 144 × 74 × 45 mm Weight: ≈ 375 g Operating Temperature: -40 to +80 °C MTBF: > 690 000 h (Ground Fixed) Country of Origin: Sweden
