10 GHz LNB with PLL and TCXO

Simply modification of the LNB with PLL and 25 MHz X-tal. With 1 ppm TCXO there is nice 10 GHz RX for tropo and satellite. You only need some receiver - SDR or classic.

Main functions:

• Ku band LNB
• Very low noise
• 1 ppm temperature stability TCXO built in
• V + H pol
• Supply over one coax
• Voltage supply +12V for V-pol, +15V for H-pol
• Bias Tee board
• V + H pol
• Supply over one coax
• Variable ATTENUATOR in the bias tee
• High voltage / current protection
• Voltage supply +12V for V-pol, +15V for H-pol More in WiKi
• Bias tee connectors: IN (LNB) = F, OUT = SMA and F
• Option: RTL-SDR receiver with 1ppm TCXO
• RTL-SDR USB receiver
• In metal box
• 1 ppm TCXO for better stability
• Input SMA connector
• SMA - SMA cable included (17 cm)
• Firmware already installed
• 8 bit, up to 2 MHz of spectrum
• compatible with: HDSDR, SDR console etc.
• Option: 3D printed POTY dual band antenna adapter
• UV stable PETG material
• 22 mm Cu tube diameter
• ONLY ADAPTER, not 2.4 GHz antenna!

⚠ ⚠ ⚠ 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 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.

Variants:

• Different 10 GHz and IF FQ
• Tropo / EME / QO-100

Set Includes:

• Ku band LNB with TCXO
• Bias Tee PCB - assembled
• Option: RTL-SDR + SMA cable
• Option: 3D printed (PETG material) POTY antenna adapter (22mm)
• POTY - ONLY ADAPTER, not 2.4 GHz antenna!

NEW VERSION WITH EXTERNAL REFERENCE

This is 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. Web page link
