Vector network analyzer of DIY:
Refer to edy555, Japan( https://twitter.com/edy555 )The related design of the circuit, modified some circuits, added battery management circuit, redesigned PCB. The simple and practical PC control software is designed. The (SNP) file can be exported from PC software for various radio design and simulation software. The improved frequency algorithm can support 900MHz measurement frequency by using the odd harmonic expansion of si5351, and design metal shielding plate, which can reduce external interference and improve measurement accuracy. The 50k-300mhz band directly output by si5351 can provide dynamic better than 70dB, and the extended 300m-600mhz band can provide dynamic better than 50dB, and 600m-900m band is better than 40dB dynamic.
This is a DIY product, which provides perfect vector network measurement function in the size of credit card. It contains a 2.8-inch touch screen, 400mah battery, which can be used offline for 2 hours. If it takes longer to measure, please connect the mobile power supply or contact me to make a version of the larger capacity battery. Tx/rx method can measure the complete S11 and S21 parameters. If S12 and S22 are needed, the connection of the transceiver port needs to be replaced manually. If there are other imperfections, you can communicate with me.
