Importance of a Tunable Filter in Mobile Applications

The process of communication has changed drastically over the years. The initiation of integrated electronic chips, development in computers, etc has given rise to advancements in telecommunications, as well (Brainly, WHAT ARE THE EFFECTS OF CHANGES OF TELECOM REVOLUTION ON THE HUMAN LIFE STYLES, 2015). The development in technology has led to the invention of smart phones. The number of smart phone users has increased from 1.57 billion, in 2014 to 2.32 billion in 2017 (Statista, NUMBER OF SMARTPHONE USERS WORLDWIDE FROM 2014 TO 2020 (IN BILLIONS)).  Hence, it has become important for wireless mobile phones to have tunable radio frequencies, since mobile phones need to operate over multiple bandwidths. This can be done with the help of a tunable notch filter. This is a kind of an electric filter, whose frequency can be varied by adjusting its components. Due to this feature, it makes the filter useful for devices that need to operate on different frequencies. The following points explain more in detail about the importance of tunable filters:

Requirement

With the arrival of 4g mobile phones in the market, it has become important with tunable solutions such as tunable RF filters, due to their varied benefits. Some of these include lower operating frequencies, higher data rate expectations from potential consumers, return on investment expectations from operators, etc (books.google.co.in, TUNABLE RF COMPONENTS AND CIRCUITS, 2015). This type of a filter is an integral component for its performance in software-dominated cell phones, instead of hardware ones. Tunable filters can help allow faster and better quality of communications. Along with this, it can also help to increase the life of devices, in which they are being used.

Market overview

Tunable filters have varied benefits and can be used in different technologies. However, the use and market growth of these filters is still at a very early stage (books.google.co.in, TUNABLE RF COMPONENTS AND CIRCUITS, 2015). One of the reasons, for this might include the absence of many manufacturers of these types of products. However, in the coming years the growth of tunable RF can be expected. It is also estimated that by 2020 the commercialization of 5g technology will begin; thus, increasing the chances for challenges and developments for tunable solutions (books.google.co.in, TUNABLE RF COMPONENTS AND CIRCUITS, 2015). Businesses can buy tunable band-reject filters, RF shield boxes, etc from Ranatec. More information about their different products and services can be found on their website.
