DX Patrol QO-100 Up Converter

The DX Patrol QO-100 Up Converter is a precision-engineered transmitter designed for stable, accurate uplink to the QO-100 (Es’hail-2) satellite. Compact, efficient, and exceptionally clean in performance, it offers reliable conversion from various IF frequencies to the 2.4 GHz transmit band, making it an excellent choice for any serious QO-100 ground station setup.

Built around an Analogue Devices ADF4351 synthesiser, the converter delivers a clean and stable signal with spurious emissions below –50 dB. The internal 10 MHz TCXO (500 ppb) provides superb frequency accuracy, while an external GPSDO input allows for fully lockable operation when even higher precision is required. Users can easily select one of four factory-programmed local oscillator frequencies via the onboard DIP switch, ensuring simple integration with different transceiver IFs.

With a 200 mW (23 dBm) RF output and support for 1–3 W RF input (6 W maximum), the DX Patrol Up Converter provides plenty of flexibility for a range of operating conditions. TX and Standby modes are automatically managed through RF VOX, while LED indicators clearly display PLL lock and transmit status. The unit is housed in a robust metal enclosure with SMA connectors and a new DC plug input, offering both durability and excellent RF shielding.
