About RF & Wireless
RF and wireless components enable the transmission and reception of information through electromagnetic radiation across a defined frequency spectrum. These devices form the core of any wireless communication architecture, from short-range IoT sensors and RFID systems to long-range cellular infrastructure and industrial telemetry networks.
The RF & wireless category encompasses a broad range of active and passive devices, including RF connectors, transceivers, switches, amplifiers, filters, and identification systems. Radio frequency identification technology represents a specialized subset of RF applications, using tags and readers to wirelessly store, access, and transmit data for inventory management, asset tracking, access control, and supply chain automation. Radio frequency identification cards are among the most widely deployed RFID form factors, used across industrial facilities, logistics operations, and secure access systems.
RF and wireless components are specified across telecommunications infrastructure, automotive systems, industrial automation, aerospace and defense, medical telemetry, and consumer wireless devices.
Types of RF & Wireless Products We Offer
RF Transceiver ICs
An RF transceiver seamlessly integrates both transmit and receive functions into a single IC, enabling reliable bidirectional wireless communication in a compact, power-efficient package. These versatile devices are core components in wireless sensor networks, IoT modules, two-way radio systems, and cellular equipment. Browse Suntsu’s RF transceiver ICs for available options across various frequency bands and communication protocols.
RF Switches
RF switches route high-frequency signals between multiple ports with minimal insertion loss and high isolation, making them essential in antenna switching, test and measurement equipment, and multi-band communication systems. They are specified in applications where signal path selection must be achieved without degrading RF performance. Explore Suntsu’s RF switches collection for available configurations.
RF Connectors and Interconnects
RF connectors provide the mechanical and electrical interface between RF cables, PCBs, and system enclosures. Connector selection directly impacts signal integrity, impedance matching, and insertion loss across the signal chain. These components are used across all RF-enabled systems from handheld radios to base station infrastructure.
RFID Components
RFID components include tags, readers, antennas, and interface ICs that together enable contactless identification and data capture. These systems support a range of frequencies including LF (125 kHz), HF (13.56 MHz), and UHF (860–960 MHz), with each band suited to different read range, data rate, and environmental requirements. For applications operating on the 13.56 MHz HF band, a precision-tuned NFC coil is essential to establish the inductive link required for reliable data exchange between the tag and reader.
How to Choose the Right RF & Wireless Component
Selecting the correct RF or wireless component requires careful evaluation of system-level requirements and operating environment:
Operating frequency and band: Confirm the frequency band your application operates in and select components rated and characterized for that range. Mismatched frequency ratings degrade performance through increased insertion loss, poor isolation, and impedance mismatch.
Impedance matching: Most RF systems are designed around a 50-ohm impedance standard. Verify that all components in the signal chain, including connectors, switches, and transceivers, share a consistent impedance to minimize reflections and signal loss.
Communication protocol and range: For wireless and RFID applications, define the required communication protocol (Bluetooth, Zigbee, LoRa, UHF RFID) and read range before selecting a transceiver or RFID IC. Protocol compatibility between tags, readers, and host systems is essential for reliable data exchange.
Power consumption and supply voltage: RF transceivers and active RF components vary significantly in power draw. Battery-powered and energy-harvesting designs require components with low sleep current and efficient transmit power levels matched to the application’s range requirements.
Environmental and mechanical requirements: Industrial and automotive RF deployments require components rated for extended temperature ranges, vibration resistance, and sealed or ruggedized connector interfaces. Verify environmental ratings against the deployment conditions before finalizing component selection.
