This is the 10 GHz LNB (Low Noise Block) with external reference input. LNB needs 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 (25 MHz) or 10 MHz reference signal (GPSDO) 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. High pass filter and 25 MHz notch filter for IF line. You can still switch between V and H polarisation by supply voltage. You can use it for QO-100 satellite and also for Tropo contesting/DXing.
Main functions
Ku band LNB
- Very low noise converter block
- External 25MHz PLL reference signal over IF coax cable
- LO = 9750 MHz: 10489 - 9750 = 739 MHz IF etc.
- V + H polarisation
- Supply over one coax
- Voltage supply +12V for V-pol, +15V for H-pol
Bias Tee BOX
- DC supply over one coax together with 25 MHz PLL reference signal
- Build in TCXO with 0.2 ppm as alternative to 10 MHz reference input
- 10 MHz reference input for very high frequency precision and stability
- LO = 9750 MHz: 10489 - 9750 = 739 MHz IF etc.
- High Pass Filter in IF RF line
- 25 MHz Notch Filter at RX output - version MK II.
- 10 MHz input simply X-tal filter - version MK II.
- Variable ATTENUATOR in the bias tee
- High voltage/current protection
- Voltage supply +12V for V-pol, +15V for H-pol
- Bias tee connectors: IN (LNB) = F, OUT = SMA, 10 MHz ref IN = SMA
- 4pcs self adhesive feet pads included
- DC plug included
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!

Technical Parameters
| LNB local oscillator | 9750 MHz (with 25 MHz source) |
|---|---|
| Conversion gain of LNB | > 50 dB |
| LNB IF | 739 MHz for 10489 MHz (QO-100) 618 MHz for 10368 MHz |
| Reference 10 MHz input power | -3 dBm to +13 dBm |
| Stability with 10 MHz reference | depends on reference source |
| Stability with 25 MHz TCXO (0.2 ppm) | 0.2 ppm (X 390) |
| 25 MHz cut off to RX output port | > 50 dB |
| Frequency error with TCXO | max 3 kHz, typ. less than 1 kHz (after 5 minutes) |
| DC power | +12 V for Vertical polarisation (NB) +15 V for Horizontal (WB) |
| Bias Tee IF loss | typ. less than 2 dB |
| Variable Attenuator on IF | 0 dB to NO signal |
⚠ IMPORTANT NOTE: This Bias Tee box is designed for 10 MHz external reference source but you can also use internal 25 MHz TCXO, which is 0.2 ppm. Frequency error is max. 3 kHz.
⚠ IMPORTANT NOTE: Do NOT forget that the quality of the 10 MHz signal source has got final effect on the quality of the output signal. With added phase noise by PLL multiplying.
MK II: Internal duplexer - cut off 25 MHz signal to RX output
10 368 MHz to 618 MHz locked to external 10MHz reference
10 499 MHz to 749 MHz locked to external 10 MHz reference
