Information is FREE! Progress is MUST! Awakening is inevitable!
We have gone over NanoVNA so many times in the past. I did a complete review of the inexpensive NanoVNA last month. Furthermore, I compared it with the super-expensive Keysight N9952A Vector Network Analyzer....
There are so many new RF devices coming out these days which has pushed the envelope the technology where a common person can access it. In one of the previous posts, I demonstrated how...
Update: Now you can plot the impedance vs. distance/time plot. Click here to learn the concept. Original Post: Having a VNA opens up so many possibilities. Just last week, I reviewed the nanoVNA and...
Vector network analysers (VNA) come in all sort of price ranges. Most of them are out of reach for a typical hobbyist. Very few VNAs are available to be bought by someone like you...
Do you build RF circuits? Have you built any antennas? If the answer to any of the two questions is YES, then you know how valuable having a VNA (Vector Network Analyzer) is. Just...
In one of the previous posts we saw how we could transmit DATV using LimeSDR mini. This time we are going to use our LimeSDR mini as a RF source in our home lab....
PLL chips such as the ADF43xx, MAX287x and so on come with an integrated VCO. The frequency range on these PLL chips can extend all the way from few tens of MegaHertz to several...
Transmitting voice is something every ham operator must be doing regularly. There is a breed of hams which only stick to digital modes, while some prefer morse. Some ham operators go above and beyond...
Voice detector can find it’s use in voice-activated circuits. For example, triggering a transmitter or enabling a speech processor and so on. At the end of this blog post, we will look at one...
Remember the previous post where we generated PWM? We are going to use the PWM output from the TivaC microcontroller and drive an RF switch. I will be using the Minicircuits HSWA2-63DR+ SP2T switch...
