Waveguide flange

When we design and simulate waveguides we should attend that path input source waveguide is very important, that can make high efficiency coupling and low loss, we know that matching and coupling is very vital in Electronic and RF Devices.In waveguide excitation point is called waveguide flange in this post we want to discuss about it.

DVB-T Gnuradio TX-RX, recording video receiver in bandwidth 1MB and frequency 461M

Today we share recorded video DVB-T receiver here, we use two Hackrf One with Gnuradio, we had 1MB bandwidth and 461M center frequency.In higher bandwidth we had not any ofdm symbol and we had error restart aquisition for more info please see former our blog post this and that link. So really HackRF One in Higher 1MB bandwidth is not good and it can not haldle high carrier modulation.

Waveguide vs transmission line

We now that we use trasmission line for propogation of electromagenic waves,in transmission line we use circuit models, but in waveguide for propogation  electromagnetic waves.So we here compare and discuss about them.

The non-analytical solutions available solving electromagnetic equations with the introduction of software

And any electrical engineer you should familiar with Maxwell's equations. In electronic engineer we work with electronic or photonic or hybrid deveice and gate of understanding this deveice is electromagnetic and solid state physics and some electronic devices books.So every model that we see in electronic deveices is derived from Maxwell's equations. We in Bsc degree we solve electromagnetic question in a analytical methods, but in real world we can not use analytical methods,So we should swtich to methods course numerical analysis.So in this blog post we want to discuss about  numerical method to solve Maxwell's equation for different problems.

Observing Random Jitter in HackRF One in High Bandwidth with High Carrier Modulation

Yet i work on DVB-T in HackRF one, in TX we can send DVB-T and we receive it with a hardware dongle DVB-T. but for receiving with SDR Based we had error: see this link for our older work or this link.
