DXpatrol QO-100 Upconverter Mk4

The QO-100 upconverter (upconverter) converts an input signal to the 13cm (2.4 GHz) band, suitable for operation via the QO-100 satellite. The frequency band of the input signal can be selected, depending on the available transmitter. Input signals of 10m, 2m, 70cm or 23cm are possible. The input power should be approx. 1 to 3 watts and must not exceed 6 watts.

A highly stable 10 MHz oscillator signal must be available for mixing the signals. The QO-100 Upconverter Mk4 comes with a stable, internal TCXO. Alternatively, an external reference signal, for example from a GPSDO, can be fed in. The output signal is of high spectral purity, undesired mixed products are suppressed with 50 dB or more.

The QO-100 upconverter from CT1FFU is supplied in a metal housing. All RF connections are SMA sockets, the power supply must be 10 to 15 V, current consumption approx. 300 mA.
