The device from DO5DSH converts a low frequency radio signal to the 13cm (2.4GHz) band and is suitable for operation via the QO-100 satellite. The frequency band of the input signal can be selected from 10m, 6m, 2m, 70cm or 13cm. The input power can be between 10mW and 5W.
No additional mixing signals are required to upconvert the low frequency IF signals of your ham-radio transceiver. The Localino QO-100 Upconverter-H provides all signals internally via (low ppm) TCXO and high-precision PLL. The output signal has a high spectral purity; undesired mixing products are suppressed by additional filters.
The QO-100 Upconverter-H comes in an aluminum housing including internal passive cooling. All HF connections are SMA sockets. The power supply should be 10V to 24V, with typically 13.8V or 20V in operation, depending on desired output power. The current consumption in standby is about 60mA @ 20V, TX operation draws approx. 900mA @ 20V.
Application
To become QRV on the QO-100 satellite, a clean RF signal on the 13cm band is required. An upconverter is used here so that existing ham radio transceivers can continue to be used. The transmission signal can be provided by a shortwave or VHF transceiver. The QO-100 Upconverter H from DO5DSH can be set to the 10m, 2m, 6m, 70cm or 13cm band input by jumper.
The QO-100 Upconverter-H works with a digital HF vox. Instead of an analogue VOX, a digital VOX ensures that the PA switches reliably even with low input power and dynamic input levels (such as is usual with SSB signals). In addition, no separate PTT line is required. The control power should be between 10mW and 5W. The output power of up to 10W allows you to work directly with the satellite without an additional amplifier and small antenna dishes.
With the QO-100 Upconverter-H you can also work
with e.g. ADALM PLUTO and 13cm signals, since the device has two 2.4GHz inputs to the amplifier.

Caution
Even though the IF input is protected, you should not overdrive it.
Maximum input power levels must be taken care of! Measure your power level at the IF Input of the Upconverter-H before operation (your transceiver TX power at the end of the cable).
Take care of your SWR (S11, reflectivity) of your 2.4GHz antenna. It must be ensured to have a good SWR (SWR < 1.9 / S11 < -10 dB). The power amplifier may break if you operate on bad antenna SWR.
With a typical POTY or helix feed, 80cm dish antenna and optimal input power levels the RF signal power of the Upconverter-H can exceed the nominal power level at the QO-100 satellite and cause LEILA to trigger. In this case, lower the IF input power levels of your signal or DC supply voltage. Please take care when using QO-100 Upconverter-H.
