RF modules are designed to simplify wireless development and certification by minimizing the amount of RF expertise necessary to wirelessly enable a wide range of applications. These modules are developed with the latest standards-based protocols to enable many applications incorporating Internet of Things (IoT), Smart Applications, and Machine to Machine communication. These devices come with a broad range of options—some with a microcontroller on board and available in a variety of form factors, antenna configurations, and power options to suit any consumer, commercial or industrial design.
Timing devices are frequency sources and are often referred to as clocks or clock generators. A clock signal is a stable signal that oscillates at regular intervals, and is necessary for electronic circuits to work properly. All electronic circuits operate with reference to a clock signal that provides timing cues to enable them to execute their functions; it also allows them to coordinate or synchronize with peripherals and other devices. These timing devices are indispensable for ensuring the proper function of electronic equipment.
Surface Acoustic Wave (SAW) RF components include filters, duplexers, diplexers, resonators and frequency control devices. The resonant frequency of a SAW device is set by the mechanical properties of the material and it can used at much higher frequencies with less drift and very little variation with age. SAW devices operate at the high frequencies necessary for high speed wireless communication.
Antennas are the key to seamless wireless communications, and in today’s connected world there are a wide variety of frequencies, protocols, form factors, and applications that affect your design. TTI offers a broad selection of antenna solutions from the industry’s premier suppliers. See also Antenna Resource Center
EMI and RFI filters are passive electronic devices meant to suppress conducted EMI/RFI emissions. They can be attached to specific devices to limit or suppress their EMI/RFI output, or to inhibit their susceptibility to EMI/RFI emissions from other devices. Because there are many different criteria to consider when selecting an EMI/RFI filter, it’s important to know the characteristics of both the device being protected and the filter selected. The most common types of EMI/RFI filters are low pass, high pass, band pass, and band stop/reject filters.
A ferrite bead, or ferrite choke, is a simple hollow cylinder or bead that is made of ferrite material used to suppress or filter the amount of high frequency electromagnetic interference (EMI) noise found in electronic circuits.
With the new requirements of higher frequency RF protocols, connector components have been redesigned to meet strict low loss requirements in micro-miniature and sub-miniature packages. The connectors and cables in RF designs are following market changes to provide OEMs with trusted connections, reliable interfaces and portable features. The key to high performance in RF designs is ensuring each stage in the signal flow provides the best signal to noise ratio possible, with the lowest loss of signal strength.
RF and microwave switches are used to route high frequency signals through transmission paths. They come in different configurations, providing the flexibility to create matrices and automated test systems for many different applications.
Wireless networks for industrial automation enhance the ability to gather time-critical information, digest it, and react – key to continuously adapting to change with increasing reliability and profitability. The evolution in wireless technologies has opened the door to a new class of plant automation architecture that offers adopters a significant strategic advantage. Driven by substantial and measurable cost savings in engineering, installation and logistics, as well as dramatic improvements in the frequency and reliability of field data collection, automation experts and IT professionals are presented with the opportunity to deliver a significant, positive impact to the bottom line.
The cost reduction of communicating wirelessly has driven the communication industry evolution to RF wireless networks. Due to the absence of physical infrastructure, wireless communication has advantages that often include collapsing distance or space and the flexibility of mobile receivers that communicate anywhere within the transmission tower distance.
Wireless technology has made great strides in the healthcare field and is a platform of many uses for administrators, clinicians and support personnel. The role of radio frequency in communications has become standard and vendors continually search for ways to integrate new applications into the domain. Medical devices have unique wireless protocols that are suited to the point-of-care deployment of devices in the healthcare industry; wireless adoption and standardization is still evolving.
Wireless communication networks have evolved rapidly over the last decade and utilized a wide range of frequency bands for their operation particularly in the microwave band region. The devices using wireless communication are naturally more susceptible to interference from airborne phenomenon and are more likely to emit unwanted electrical noise.
Satellites are used in public safety, broadband media, telecommunications, utilities, military, weather monitoring and internet connectivity. Some of the newer satellites are the size of a shoe-box. In 2018 there were 111 successful rocket launches with payloads ranging from 1 to several satellites each. Every satellite uses some portion of the RF spectrum to communicate with the ground and other satellites. These are the RF links that transmit telemetry or payload data from the satellite to the ground and the links that transmit command or uplink data from the ground to the satellite. There are modems (short for modulator/demodulator) on both sides of these links, one on the satellite and one at the ground antenna.
