NJR2828 Ka-Band O3B PLL Low Noise Block Downconverter (LNB)
The New Japan Radio NJR2828 PLL Ka-band series Low Noise Block Downconverter (LNB) is specifically designed to be used in conjunction with O3B satellites. The NJR2828 series is available in two different configurations- High Frequency Ka-band NJR2828H and lower frequency operation NJR2828L. The NJR2828L is capable of Ka-Band frequency reception from 17.852 to 18.588 GHz with a local oscillator frequency of 16.80 GHz, while the NJR2828H operates from 18.372 to 19.271 GHz with a 17.40 L.O. frequency.
