The Radio Design Process

If you want to design a radio system that uses a hybrid combiner and other important hardware, you may need a college degree. Depending on your mechanical skills, you might be able to build a system without a degree; however, because the configuration process is complex, a solid education can be very beneficial. If you’d like to test your skills, you may be able to construct a reliable radio system by following a few steps.

Pick a Proper Frequency

When selecting a frequency, always consider the range capabilities. If you put the antenna in a spot on the radio that’s not restricted, the process of picking the best band for the device will be easy. However, if you’re going to build a product for consumers, several key adjustments must be made. In the consumer world, radios that have an unexposed antenna are popular. When designing these radios, construct them strategically so that they can operate efficiently for over a year while using a coin cell battery.

Antenna Options

The antenna is a very important component since it can affect the radio’s design and efficiency. If you select a commercial-grade antenna, you’ll have more frequency band options. Most stores that specialize in radio accessories sell:

Monopoles
Dipoles
Loops

When choosing an antenna, carefully consider any dimensional length constraints. Also, determine whether or not a trace can be used during the design process.

Range

The transmitter’s output and the radio’s operating frequency will influence the overall range. Other things can also impact range, such as:

Motions
Atmospheric conditions
Obstacles

If you’re concerned about range, focus on the transmitter output power because it can greatly affect performance. This is why professional engineers use a high output transmitter when an antenna has decreased efficiencies.

Modulation

Although there are a variety of modulation options, most radio engineers pick ASK because it’s easy to use and inexpensive. Higher bands usually have very sophisticated features since the frequencies can get crowded.

Overall, the process of building a radio is fun, rewarding, challenging. However, because there are many important protocols and guidelines, most designers prepare by taking various courses in college. Attending college is a smart decision since many automotive companies and telecommunication business need highly skilled radio engineers.
