Creative Video Production for RF-Lambda
This project was both fun and a challenge for us to produce. It took us almost 4 weeks just to research this topic before we began to think of a concept and script for RF-Lambda. In all honesty, before we began working on this video production, the only microwave products we knew were the ones that heat our foods. Little did we know we were about to go way beyond the gravity pull. We learned a lot and hopefully we have some space station friends we can catch a ride with – one day. We can dream can’t we?
RF-Lambda is an ISO 9001:2008 certified and internationally renowned company specialized in the development and manufacture of high-quality microwave products for the wireless infrastructure, satellite communications, medical, consumer product, and defense sectors. They make the stuff that allows technology to do what it does – Here is a link to their products.
What is RF? –
Radio frequency (RF) is any of the electromagnetic wave frequencies that lie in the range extending from around 3 kHz to 300 GHz, which include those frequencies used for communications or radar signals. RF usually refers to electrical rather than mechanical oscillations. However, mechanical RF systems do exist (see mechanical filter and RF MEMS).
Although radio frequency is a rate of oscillation, the term “radio frequency” or its abbreviation “RF” are used as a synonym for radio – i.e., to describe the use of wireless communication, as opposed to communication via electric wires.
To receive radio signals an antenna must be used. However, since the antenna will pick up thousands of radio signals at a time, a radio tuner is necessary to tune into a particular frequency (or frequency range). This is typically done via a resonator – in its simplest form, a circuit with a capacitor and an inductor form a tuned circuit. The resonator amplifies oscillations within a particular frequency band, while reducing oscillations at other frequencies outside the band. Another method to isolate a particular radio frequency is byoversampling (which gets a wide range of frequencies) and picking out the frequencies of interest, as done in software defined radio.
The distance over which radio communications is useful depends significantly on things other than wavelength, such as transmitter power, receiver quality, type, size, and height of antenna, mode of transmission, noise, and interfering signals. Ground waves, tropospheric scatter and skywaves can all achieve greater ranges than line-of-sight propagation. The study of radio propagation allows estimates of useful range to be made.
