RF Demo Kit Smith Chart Pcb

RF Circuit Filter Test Training Analysis Board Swr Impedance Matching Attenuator 50ohm Load Thru Short Open 433mhz Lc Low High Band Filter Rf Calibration

      This set is a comprehensive training kit developed for understanding rf circuits, seeing impedance behaviors and making practical measurements with analysis devices. The same set also contains a fully detailed Smith Chart Pcb. Monitoring the measurements on the smith chart and examining impedance transformations on a physical surface can be performed. It is an ideal set for those who want to learn rf, those who want to practice using a VNA and for educational institutions.

     There are 18 different rf structures on the kit; filters, impedance loads, short circuit, open circuit, load, thru elements and fixed attenuator circuits are presented on a single board. There are 2 rf connection cables alongside the board. The board is small and light, suitable for carrying.

The rf elements and functions on the kit:

1) Filter modules: Thanks to these filters, you can directly observe different frequency behaviors. There are 4 types of filters on the board, each having separate test pads.

• LPF - 30MHz (Low Pass Filter)
• HPF - 100MHz (High Pass Filter)
• BPF - 433MHz (Band Pass Filter)
• BSF - 6.5MHz (Band Stop / Notch Filter)

2) Impedance loads and swr elements: These sections show examples of mismatched loads in real systems.

• 33ohm (SWR approximately 1.5)
• 75ohm (SWR approximately 1.5)

3) Simple rf elements: Each prepared to show the impedance behavior on the smith chart:

• Series inductance
• Series capacitor
• Parallel inductance
• Parallel capacitor

4) Calibration type connections

• Short (Short circuit)
• Open (Open circuit)
• Load (50ohm load)
• Thru (Direct connection)

5) Attenuator sections: Allows you to see the frequency response and behavior of rf attenuators.

• ATT - 5dB
• ATT - 10dB
