RF / Microwave Coaxial Connectors with SwitchImplementing Wireless Functionality in IoT Devices: Application Examples and Challenge-Solving Guide

As IoT advances, many people involved in development and manufacturing face challenges like the following: "We want to equip our products with wireless functionality, but radio frequency measurement (RF measurement) and certification testing are difficult," "Even if we can conduct evaluations, we do not have the measurement environment that can support processes up to mass production inspections."

Murata offers an extensive lineup, from manual probes for evaluation, to auto probes for mass production.
If you use Murata's RF / microwave coaxial connectors with switch (hereinafter "switch connectors") and dedicated probes, you can reliably and smoothly implement wireless functionality.

Switch Connectors and RF Probes Suitable for RF Measurement of 3GPP-Compatible Devices

Our switch connectors and radio frequency (RF) probes support the radio frequency measurement (RF measurement) of wireless communication devices, including mobile devices compliant with Third Generation Partnership Project (3GPP) specifications.
Mounting our switch connectors between RF circuits and antenna circuits and then using our dedicated probes makes it possible to accurately measure the characteristics of those circuits without mutual interference.

Normally, the signal passes through the switch connector. Mating with our probe makes it possible to measure the RF signals by separating the RF circuit and ANT circuit.

RF Measurement Solution That Supports a Wide Range of Wireless Standards

In addition to 3GPP-compliant signals, such as LTE and 5G NR, our products support the measurement of a wide range of wireless signals, including Wi-Fi®, Bluetooth®, GPS, and UWB.
This makes them ideal for various evaluations of wireless communication devices, such as transmit power, frequency stability, and spurious emission measurement.

Makes Major Certification Tests Easy with One-Touch Operation

You can use our products in wired tests, such as those of the Federal Communications Commission (FCC), the Conformité Européenne (CE), and the Technical Regulations Conformity Certification System (Giteki).
Simply apply our dedicated probes to complete the connection for certification testing. Unlike conventional methods, there is no need to scrape the circuit board and route wiring.
This significantly reduces the testing preparation time to contribute to speeding up certification acquisition.

Accurate Measurement with High Isolation

When our dedicated probe is mated, the RF circuit and antenna circuit are separated to prevent mutual interference.
This improves the accuracy of evaluations, such as transmit power, frequency stability, and spurious emission measurements.

Low-Loss Switch Connectors and Dedicated Probes That Do Not Affect RF Performance

Our switch connectors and dedicated probes achieve a low voltage standing wave ratio (VSWR) and low insertion loss.
This minimizes the signal degradation during measurement to contribute to stable RF measurement.

Easy Measurement with Dedicated Probes

Murata's dedicated probes have a wide guide range and a structure that absorbs mounting misalignment (position errors). This allows anyone to easily perform stable measurements.
We offer both manual and auto product lineups to support various applications.
If you use our auto probes, integration with the automatic measurement of manufacturing lines becomes possible.
This contributes to improved productivity and cost cutting.

The tip of the probe is misaligned from the center of the switch connector, but... the structure that absorbs probe mounting misalignment works to make it possible for the switch connector and probe to mate.

Application Examples

(1) Set Manufacturers: Device Development

Mounting a switch connector between the RF circuit and antenna circuit makes it possible to perform one-touch measurement with a probe.

Circuit matching and characteristic confirmation can be repeatedly evaluated in a short time before enclosure assembly
Highly reproducible measurements can be performed from the early stages of development to reduce the number of trials required to finalize the specifications

(2) Telecommunication Carriers and Certification Bodies: Device Certification

It is possible to pre-prepare connection points suitable for wired measurement in certification testing with switch connectors.

Enables the transmit power, frequency stability, and spurious emission measurements required for certification testing, such as those of the FCC, CE, and Giteki, to be performed quickly and stably
Eliminates the need for board processing and wiring to shorten the testing preparation time

(3) Factories and EMS: Device Mass Production

Combining with auto probes that support automatic measurement enables integration with line inspections.

Communication characteristics can be confirmed in the stage before case assembly, so early detection and resolution of defects becomes possible
Can be used for the power calibration that is essential in mass production processes to reduce variations in transmit power by device
Speeds up pre-shipment inspections to improve yields by stabilizing measurement
Defects can be resolved by replacing the board before enclosure assembly to minimize material loss

(4) Set Manufacturers: Evaluation of Devices Returned from the Market

It is possible to inspect RF characteristics non-destructively via switch connectors for the re-evaluation of products returned from the market.

Isolates the failure mode without damaging the device (determines whether the issue is caused by the RF circuit or the antenna circuit)
Effective for shortening the time to investigate the cause and providing feedback to prevent recurrence
