I have limited number of N2PK VNA parts kits left for interested enthusiasts want to build N2PK VNA based on Ivan's v5.2 board.
Kit will include all of the parts from actual Ivan's BOM to build N2PK VNA and one (1) Reflection bridge (all capacitors, resistors, CWX823 oscillator, all IC's including DDS, MC transformers, extra 0.1% SMD resistors for four calibration standards...) except PCB, SMA connectors and enclosure.
More about the kit:
Will post worldwide.
I have also one assembled and tested N2PK v5.2 available, completed PCB with SMA connectors and nice heat sink on DDS, both detectors have more than -120 db dynamic range. Only enclosure, 5 & 12 volt PSU and coax cables are needed and this great VNA is completed - contact me for more info.
