External Reference Type Palapa C-band PLL LNB MODEL NO. NJS8476E / EN External Reference Type C-band PLL LNB MODEL NO. NJS8477E / EN External Reference Type Insat C-band PLL LNB MODEL NO. NJS8478E / EN <Description> This specification defines the Low Noise Amplifier and block downconverter intended for the satellite data communication downlink and VSAT system application in 3.400 to 4.200 GHz / Palapa C-band, 3.625 to 4.200 GHz / C-band and 4.500 to 4.800 GHz / Insat C-band. These LNBs have a combined 3-stage HEMT amplifier and block downconverter with Phase Locked Local Oscillator, which is constituted with a S-band VCO, Multiplier, Loop Filter, and Reference Recovery VCXO providing low phase noise. All specifications shall apply throughout the full range of the specified environmental conditions unless otherwise specified. <Line-Up> Model No. RF Frequency NJS8476E / EN NJS8477E / EN NJS8478E / EN 3.400 to 4.200 GHz 3.625 to 4.200 GHz 4.500 to 4.800 GHz Local Frequency 5.15 GHz 5.15 GHz 5.76 GHz Local Stability IF Frequency Application Depends on external reference 950 to 1,750 MHz 950 to 1,525 MHz 960 to 1,260 MHz Palapa Standard Insat <Specifications> Item Input Waveguide Flange Output Connector Noise Temperature (at 25 °C) Conversion Gain (at 25 °C) Conversion Gain Variation (at 25 °C) Local Oscillator Frequency Stability Phase Noise (SSB) External Reference Input Frequency External Reference Input Power External Reference Input Port External Reference Phase Noise Copyright © 1999 New Japan Radio Co., Ltd.
