Temwell has 26 years of experience in designing and producing helical band pass filters. The helical band pass filter are used λ/4 wavelength technology to design. We special launched RF band pass filter DIY Test Circuit Kit to help students, beginners, novice engineers and amateurs learning how to use helical band pass filter. Educators can use the helical band pass filter DIY Test Circuit Kit as teaching materials.

Through Temwell’s helical band pass filter DIY Test Circuit Kit, you can learn the skills of assembling PCB, soldering, measure parameters, frequency fine-tuning frequency, etc.

We will teach you how to measure the five parameters of helical band pass filter, including center frequency, bandwidth, rejection, insertion loss and return loss. Besides know how to install and solder helical band pass filter on PCB. You will also learn the characteristics of helical band pass filter and the ability of adjust screw to fine-tuning the center frequency.


The RF band pass filter DIY Test Circuit Kit can save your time of making PCB and searching components. For people who lack budget and time, this will be the most economical solution.


Purpose

By Temwell RF BandPass Filter DIY Test Circuit Kit learning how to measure the five parameters of helical filter, including Center Frequency (Fo), Bandwidth (BW), Rejection (Attenuation), Insertion Loss (IL) and Return Loss (RL). Besides learning how to install and weld helical filter, you will also learn the characteristics of helical filter and the ability of adjust screw to change the center frequency.
