Welcome to the Radiospurs Header Website
The series of sites dedicated Online Broadcasting, RF and Microwave analysis, design and calculators.
Form here there is a division into dedicated cum specialist sites. There are sites on FM transmitters, stereo generators and exciters. Propagation analysis using Longley Rice calculations. Passive filters, microwave filters. Power combiners / splitters, Wilkinson, Hybrid. Parallel Couplers, microstrip, stripline, edge, broadside, slabline, coax. Interdigital filters, capacitive gap, edge coupled. Antennas as Yagi, horn, helix. Its all here.
See WEB SITE DETAILS above for a more complete description of each web site.
The Radiospurs RF Toolbox Site
A Welcome
If you know what this image is, then you will have no problems handling the site information.
RF Broadcasting is an extremely wide topic, impossible to cover on such a small website, so here we concentrate on technical aspects: There are calculators
for power combiners, microwave components, propagation analysis, RF filters.
The RDS generator is an innovative symbolic modulation design, easily extended to the new V2.0 RDS. Then there is the fully digital
stereo generator based upon the Analog Sharc series DSP.
The Filters toolbox allows a wide range of passive filters to be designed, Butterworth, Chebychev, Bessel, Linear Phase, Elliptic. I rather like the Chebychev type 11 as a harmonic filter.
The Microwave Filters cover interdigital, side coupled, capacitive end coupled.
There is a specific site for RF propagation analysis using the Longley Rice algoritms with a few later updates. Covering
the civilised world pt to pt and broadcast analysis can be carried out.
Having got the propagation results, these is a a selection of calculators for antennae of popular use, Yagi, Log Yagi, Horns, Helix
