The report finds that growth of this market is mainly driven by the factors such as the growing demand for smartphones and connected devices and increasing use of long-term evolution (LTE) network. RF tunable filters based on MEMS capacitors and digitally tuned capacitors are the most popular types of tunable filters used in consumer electronic devices. These tunable filters are widely used in smartphones to minimize the manufacturing cost. Also, these tunable filters are used in smartphones due to the rising telecommunication data traffic as they provide high temperature stability in small cells.
Radar systems are expected to hold the largest share of the RF tunable filter market based on systems, in terms of value, by 2023. Highly reliable RF tunable filters, which can be used even in harsh environmental conditions for proper communication, are required to adhere to military standards. These standards include environmental, electromagnetic capability; nuclear survivability; and electrical characteristics of a digital interface. In military systems, RF tunable filters are mainly used in handheld and software-defined radios, radar systems, and test and measurement systems.
The RF tunable filter market for smart cities is expected to grow at the highest CAGR from 2018 to 2023. The growth of the market for this vertical is attributed to the successful implementation of smart city projects, which heavily depends on technologies such as data communications, cloud, mobility, and sensors that collectively form the IoT. Rapid developments in these areas, in recent years, have enabled better connectivity of objects, resulting in the complete development of smarter ecosystems.
