YO4HFU
LNB PLL for Eshail QO-100 downlink 10GHz

 

 

AMIKO LNBs
AMIKO L-107 SINGLE ECO LNB: TOP & BOTTOM
AMIKO L-203 PREMIUM TWIN LNB: TOP & BOTTOM

Amiko L-107 contain TFF1015 PLL IC drived by 25MHz. Band Pass Filter can be observed in front of TFF mixer.
Amiko L-203 contain RDA3565ES PLL IC drived by 27MHz. Broadband design, only LC trap in front of RDA mixer.
Amiko L-203 is same design like OCTAGON, AVENGER.

Default Local Oscillator: 9,75GHz or 10,6GHz (22KHz tone enabled).

QO-100 test using AMIKO L-203 LNB and 65cm dish. Strong signals and good PLL stability!
AmikoL-203 has more gain compared with L-107 due to wide bandwidth frontend (no band pass filter).
LMX2332 PLL is designed to generate 25MHz or 27MHz , signal necessary to achieve excellent stability of the LNB L.O. using 10MHz reference (GPSDO or OCXO).
27MHz level it is not critical, any clean signal between -30dBm...+5dBm. Power restart of LNB is required after disconnection/connection of external 27MHz.

See more details regarding OQ-100 home made transverter.
