SMW X LNB 7.90-8.50 GHz 1 Band | Gen 2

Description

SMW X LNB 7.90-8.50 GHz 1-Band PLL LNB The SMW X LNB 7.90-8.50 GHz 1-Band PLL LNB is a precision low-noise downconverter engineered for X-band SATCOM and radar applications. It combines exceptional phase-noise performance with external 10 / 100 MHz reference (with automatic fallback to internal ±25 ppm), RS-485 Modbus RTU monitoring, and configurable alarms for LO lock, LNA, and voltage conditions. Input Frequency: 7.90 – 8.50 GHz Local Oscillator: 6.95 GHz Output Frequency: 950 – 1550 MHz Noise Figure: typ. 0.60 dB (42 K), max 0.69 dB (49 K) @ 23 °C Gain: typ. 60 dB (±0.1 dB / 24 h), flatness ±0.4 dB (30 MHz) / ±2 dB (full band) Phase Noise: -45 @ 10 Hz • -75 @ 100 Hz • -95 @ 1 kHz • -100 @ 10 kHz • -105 @ 100 kHz • -122 @ >1 MHz Image Rejection: ≥ 35 dB Group Delay: ± 1 ns max Output P1dB: ≥ 15 dBm Output IP3: ≥ 26 dBm Input VSWR: 1.5 : 1 max Output VSWR: 1.5 : 1 max Reference: External 10 / 100 MHz (+5 to +10 dBm) with fallback to internal ±25 ppm Input Connector: WR-112 / R84 flange (PBR-84), pressurizable 0.1 bar max Output Connector: N-f (50 Ω), optional SMA-f (50 Ω) Power Supply: +12 to +28 V DC (3 W typ.) M&C Interface: RS-485 (Modbus RTU) with sum alarm (LNA fail, LO lock, voltage, signal status) Dimensions: 135 × 56 × 51 mm (N); 128 × 56 × 51 mm (SMA) Weight: 381 g (N) / 375 g (SMA) Operating Temperature: -40 to +80 °C MTBF: > 690 000 h (Ground Fixed) Country of Origin: Sweden
