The growth of the radio frequency (RF) diplexer market is expected to be driven by the increasing number of Internet of Things (IoT) devices. IoT refers to a network of physical devices equipped with sensors, software, and other technologies that connect and exchange data over the internet. The surge in IoT devices is due to their capability to improve efficiency, automation, and real-time data insights across various industries and applications. RF diplexers are essential for IoT devices as they effectively separate and manage different frequency bands, enabling the simultaneous transmission and reception of multiple signals without interference. For example, a report by Ericsson, a Swedish telecommunications company, stated that global IoT connections reached 15.7 billion in 2023 and are projected to grow to 38.9 billion by 2029. Consequently, the rise in IoT devices is fueling the growth of the RF diplexer market.

Leading companies in the RF diplexer market are developing advanced solutions, such as E-Band radio solutions, to offer enhanced features to their customers. E-Band radio solutions operate in the millimeter-wave spectrum, specifically in the frequency range of 60 to 90 GHz. For instance, in August 2023, Filtronic, a UK-based manufacturer of RF, microwave, and millimeter-wave components, launched the HADES X2 active diplexer. This diplexer is notable for its high performance and cost-effectiveness. Featuring dual high-power amplifiers with a typical PSAT of 30 dBm, the HADES X2 enables exceptional linear transmission powers for long-range E-Band communications. This is achieved through the integration of two gallium arsenide (GaAs) monolithic microwave integrated circuits (MMICs), which are precisely matched and power-combined in the waveguide. As a result, the HADES X2 delivers maximum power efficiency and signal quality, ensuring superior performance in demanding communication environments.

In November 2024, MACOM Technology Solutions Holdings Inc., a US-based developer and manufacturer of high-performance semiconductor products, acquired ENGIN-IC Inc. for US$14.2 million. Through this acquisition, MACOM aims to strengthen its GaN-based monolithic microwave integrated circuit (MMIC) and integrated microwave module design capabilities, particularly for high-frequency and defense-oriented applications. ENGIN-IC Inc. is a US-based fabless semiconductor company that designs advanced GaAs and GaN MMICs and integrated RF modules, with a focus on defense and high-frequency markets.

A radio frequency (RF) diplexer is a passive device utilized in telecommunications and signal processing to combine or separate signals based on their frequency. It enables multiple RF signals to share a single transmission medium while reducing interference among them. The primary role of an RF diplexer is to divide signals into different frequency bands.

The main types of radio frequency (RF) diplexers include crystal type, ceramic type, and others. Crystal-type RF diplexers use crystalline materials to split and mix radio waves. They are made with materials such as silicon gallium arsenide and silicon-germanium and are used in cellular, wireless, military, fiber-optic (FO) communication, consumer, automatic, and various other applications. These diplexers are utilized by various end-users, including the petrochemical industry, residential and commercial sectors, power generation, and more.
