Inmarsat L-Band Uplink Bandpass Filter (1626.5–1660.5 MHz) Low Noise Amplifier Frequency (MHz) Typical Attenuation (dB)PRODUCT OVERVIEW Inmarsat's L band mobile satellite service relies on two distinct frequency ranges: downlink from the satellite to terminals runs from 1525 to 1559 MHz, while the uplink from terminals back to the satellite runs from 1626. 5 to 1660. 5 MHz. This filter covers that uplink window precisely, centered at 1643. 5 MHz with a 34 MHz passband, with less than 5 dB of insertion loss across the full band. The 1626. 5 to 1660. 5 MHz uplink is the
