3D Contour Farfields in Microwave and Light Devices

In this here we want to discuss about farfields in microwave and light devices.farfield is a polar of fileds or power that is used in antenna design.

Selectivity and sensitivity in SDR Hardwares

Finally we worked on RTL-SDR and HackRF One and USRP in practical test and different moudlation like GFSK,DVB-T,ATSC,OFDM,DMR.With all of them we can see spectrum, it is not final purpose, we emphasize ,purpose is data in digital radio communication.So which SDR hardware can handle  data extracting with different moudation and protocols like GSM or even LTE and so on.

Four-Ports Waveguide Microwave Functions

In this blog post we want to discuss about a S-Paramter of a waveguide. We know that in Microwave we use S-Parameter for descriping these deveices.

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.
