Description

Simply modification of the satellite Low Noise Block (LNB) with PLL and 25 MHz X-tal. There is nice 10 GHz receiver down converter for tropo and satellite with 1 ppm TCXO. You only need some receiver at IF frequency - SDR or classic. Very good frequency stability with built-in TCXO. You can choose between three different version with different IF output frequencies.


Main functions


Ku band LNB

  • Very low noise block - down converter
  • 1 ppm temperature stability TCXO built-in
  • Input of LNB is designed for 10 to 12.5 GHz
  • Vertical and Horizontal polarisation
  • Voltage supply +12V for V-pol, +15V for H-pol*
    * NEW IF IC in LNB needs +18V to switch to H-pol.

Bias Tee

  • Low Insertion Loss
  • Supply voltage and IF over one coax
  • Variable ATTENUATOR in the bias tee
  • High voltage/current protection
  • RF signal protection limiter - max. signal 20 mW (ver. 0.4 and higher)
  • Voltage supply +12V for V-pol, +15V for H-pol*
  • * NEW IF IC in LNB needs +18V to switch to H-pol.
  • Bias tee connectors: IN (LNB) = F, OUT = SMA and F

Option: 3D printed POTY dual band antenna adapter

  • UV stable PETG material
  • 22 mm Cu tube diameter
  • POTY pipe WG fixed by M4 screw
  • ONLY ADAPTER, 2.4 GHz antenna not included!

Available as

ASSEMBLED: classic version - ready to use
ASSEMBLED: version with POTY adapter (only adapter, not 2.4 GHz antenna!) - ready to use

RECOMMENDATIONS TO BUY:

Included in package

LNB assembled and tested
POTY adapter (version with POTY)


Manual

If you want to know more please check our wiki with 10 GHz LNB TCXO manual.



When installing the LNB with a POTY antenna, remember to position it correctly in the dish focus! If you place the antenna outside the dish's focal point, the antenna gain will be reduced and unwanted lobes will form. You can read more also there: forum-amsat-dl.org

Technical Parameters

LNB local oscillator - model SDR 9750 MHz
LNB local oscillator - model 10489-432 10057 MHz
LNB local oscillator - model 10368-432 9936 MHz
Conversion gain of a LNB > 50 dB
LNB IF - model SDR 739 MHz for 10489 MHz (QO-100)
618 MHz for 10368 MHz (TROPO/EME)
LNB IF - model 10489-432 432 MHz (10489 MHz RF IN)
LNB IF - model 10368-432 432 MHz (10368 MHz RF IN)
Stability with TCXO 0.5 ppm (X 390)
Frequency error with TCXO 0 to abt 30 kHz
DC voltage +12 V for Vertical polarisation (NB)
+15 V for Horizontal (WB)
NEW IF IC in LNB needs +18V to switch to H-pol.
DC current typ. 180 mA
Bias TEE IF loss typ. less than 2.5 dB (ATT set to 0)
Variable Attenuator on IF 1 dB to NO signal

IMPORTANT NOTE: TCXO has got 1 ppm temperature stability and 2 ppm production frequency tolerance. It means that all pieces have got some small frequency offset. Depends on the piece, it is 0 to about 20 kHz. This is not a problem for SDR RX where you can set it in the software. For LNB with 432 MHz IF you have to calculate with this offset from TX frequency and set it in TRX menu.

NEW VERSION with external reference

10 MHz GPSDO with 2-way splitter qro.cz hamparts.shop

NEW VERSION: The 10 GHz Low Noise Block (LNB) modified for external 25 MHz reference for internal PLL. This signal is feeded by the same one coaxial cable as IF down. Special small Bias Tee box with TCXO or 10 MHz reference signal works as DC injector and also 25 MHz Source for LNB. There is also variable attenuator for IF signal which allows you to change IF signal from 0 to maximum. You can still switch between V and H polarisation by supply voltage.
