Description
10MHz filter for EASTAR UHP-240 satellite router.
That filter refines 10 MHz refenrence signal for TX and RX signal paths.
That version of modem uses square form OCXO generator unlike to previous UHP-100 modem with lovely sine wave generator.
It looks like not every LNB are pleasant with square reference signal.
Attenuation about 5 dB is inserted to reduce overhelming +10 dBm 10HMz signal on 50 Ohm load.
