This 144/432Mhz mixer to the 2.4GHz band is intended to be used as a dedicated up-converter to traffic on the uplink of the QO-100 satellite. The included SAW filter allows system size reduction as well as the use of an intermediate frequency (IF) of 144MHz or 432MHz with an input power of 0.5W to 3.5W maximum.
This mixer requires injecting the frequency of the local oscillator (LO) which is not included to make it an upconverter.
Delivered with: Assembled PCB board, delivered with a countersunk box to be mounted, SMA connectors to be soldered, screws and a ByPass 1nF / M3 capacitor. Assembly instructions in French to download below.
