We look at the basic concepts of active filters, design a 2nd order lowpass with TI’s filterdesign tool and then build a filter and measure the filter performance on the lab bench. Maybe you want to watch the introduction to electronics filters first, since I do reference to that video so what.
See how I approached the design of a 8 pole crystal ladder filter for SSB @9MHz and with a bandwidth of 2.4 kHz.
Check out how the antenna amplifier got designed, simulated and tested.
I did choose to build a super-heterodyne type of receiver. What alternatives do we have?
Hi all, I did build my first ham radio transceiver and I thought I let you know how I did it. This might give you ideas about your own HF experiments and give me some feedback from you guys and ideas for new projects. introduction, Types of radio receiver antenna amplifier bandpass and lowpass-filter design […]
