Good and functional RF generator with some interesting functions. Very stable signal and very reduced frequency drift once TXCO is stabilized. Pity that a shell is not available for this module and that it does not cover frequencies below 23.5 MHz (maybe possible with a lower freq quartz). Quickly shipped and well packaged in a protective box. It's a pity that the software to control it from a PC is not available.here.

Fast delivery.Good price. Wide possibilities of use. Good control, large frequency range. Errors synchronization pulse for start of spreading. I recommend it to everyone.

Rýchle dodanie.Dobrá cena. Široké možnosti využitia. Dobré ovládanie, veľký rozsah kmitočtu. Chybuje synchronizačný impulz pre začiatok rozmietania. Doporučujem všetkým.

The synthesizer is not bad. I could check up to 350 MHz that is my scope's limit. I don't have a spectrum analyzer for time being therefore I couldn't test all features but it's quite promising specifications. But most important missing point here is the PC control software. I have searched all over internet but I couldn't find a working PC control software for this module. I believe the output level drops down rapidly by frequency. The output level which is shown on the display is not correct, pretty lower and this increases by frequency. They didn't use a Ballun transformer to convert differential to single ended and that limits the performance of MAX2870. You should reset the module if you cannot see the right frequency because the module has serious bugs. They have to be corrected.
