We enjoy a very good reputation among our customers for our excellent product quality, competitive price and the best service for Circular Polarity Prime Focus Ku LNBF (10.678GHz). The LNB is usually a small box suspended from one or more short booms or feed arms in front of the dish, focusing on the focus (although some dish-shaped LNBs are above or behind the mirror). The microwave signal in the dish is picked up by the feed horn on the LNB and fed to a portion of the waveguide. One or more metal pins or probes extend into the waveguide at right angles to the shaft and act as an antenna, feeding the signal to a printed circuit board inside the LNB shielded box for processing. The low frequency IF output signal comes out of the socket on the box to which the coaxial cable is connected. The LNBF was disassembled. The waveguide from the feeder passes through the microwave radio signal collected by the dish through the central aperture, which carries the microwave radio signal collected by the antenna. The pins visible on the top and left sides of the hole extend into the waveguide and act as an antenna to receive the signal, convert it to RF AC, and process it by the board.

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. Applications Technical parameters Effect of GPSDO-TCXO Schematic PCB Options: Recommendations to buy FAQ Product details In amateur radio world you can build 10 GHz RX for QO-100 satellite, 10 GHz EME or tropo. Device is designed only for Receiving. ... Input of LNB is designed for 10 to 12,5 GHz. Original local oscillator (LO) is locked by 25 MHz reference signal and multiplied 390 - what means 9750 MHz. - small box works as DC Bias Tee, 25 MHz source for LNB, variable ATT and protections - allows you to supply DC voltage and 25 MHz reference for PLL of LNB over one coax - you can use internal TCXO with 0.2 ppm or some 10 MHz reference signal (you can select signal by the jumper JP1) - you can switch H and V polarisation - DC and RF protections! - small splitter for 10 MHz reference signal - splits 10 MHz signal to Bias Tee box and another your device (SDR, TRX etc.) - low loss 3.5 dB · - RTL-SDR USB receiver - in metal box - 1 ppm TCXO for better stability - input SMA connector - firmware already installed - 8 bit, up to 2 MHz of spectrum - compatible with HDSDR, SDR console etc. - SMA male & SMA male pigtail - about 15 cm (total length 17 cm) ... This is Low Noise Block (LNB) which works as Down Converter.

I rotate the LNB in the clamp to set the correct polarization for the station I am listening for. Europe mostly transmits vertical, and I am using the vertical probe in the LNB because it has lower noise figure than horizontal. So for Europe I simply rotate the LNB the specified number of degrees for the Dpol given by WSJT-X. I found the LNB did not want to lock to a square wave reference, so I added a Mini-Circuits BBP-27R5+ band pass filter to filter out the harmonics and leave a nice clean sine wave. Next there is that bit about combining DC, 25 MHz and 618 MHz on one coax. As discussed above, I found a pair of SV1AFN DC/10 MHz/VHF-UHF triplexers can be used. They are operating outside specifications with 25 MHz instead of 10 MHz and 618 MHz instead of 144 or 432 MHz RF. Today I did initial testing of a 10368 MHz signal source and the LNBF I hope to use for a receive-only system. The signal source is an old Qualcomm synthesizer board (thanks N1JEZ) modified to produce 1152 MHz. It should be producing harmonics that fall in several ham bands: 2304, 3456, 5760, 10368 and possibly 24192 MHz. The 10368 signal is quite strong listening with the Bullseye 10 kHz LNBF in the next room. The LNBF converts 10368 down to 618 MHz which I run into one of the cheap RTL2832 SDR receiver sticks. I mounted a switch on the side of an equipment rack to control 12V to the LNBF.

The result is better phase noise and output (IF) signal quality even when using a worse external reference signal source of 10MHz. In addition to the Crystal filters, the new Bias Tee box includes a new diplexer to separate the IF and reference (25MHz) frequencies on a single coaxial cable along with a DC power supply for the LNB. The box also includes surge protectors, a current Super-Fuse, a new electronic DC fuse, LED indication of switching from V to H polarization and a continuously adjustable variable Attenuator.

LNBs for Satellite operations on 10 GHz (QO-100)

WiMo - YOUR expert for radios and antennas. This is where you can shop for amateur radios, accessories, antennas, WiFi/ mobile radio antennas, cables etc. The LNBs from qro.cz are prepared for operation on QO-100 or for EME/Tropo DX. For this purpose, different models are offered which convert either to 432 MHz or to 739 MHz (for QO-100 operation) or to 618 MHz (for EME/Tropo operation). Thus, either an existing 70cm transceiver can be used as a repeater, or a receiver like an SDR. The LNBs either have a built-in 25 MHz TCXO as clock generator, or expect an external clock source via the same coaxial cable that is used to output the received signal. Thus, even with external clock, only one cable is needed to the LNB. The scope of delivery always includes a Bias-T, via which the LNB is supplied with voltage. The polarisation of the LNB can be switched from horizontal to vertical with different voltages. The versions of the Bias-T without 10 Mhz ref. input are supplied with voltage via screw terminals on the PCB. Connections 2x F, 1x SMA.
