RFMW announces design and sales support for a positive slope gain block from CML Microcircuits. The CMX90G301 is a low-power, 50 Ω cascadable MMIC gain block for 1.4 to 7.1 GHz applications. +1 dB of positive gain-slope across the band eliminates the need for equalization and compensates for increasing system losses with frequency. Highly integrated, the CMX90G301 minimizes component count and board area. RF ports are matched to 50 Ω with DC-blocking capacitors. An active bias circuit allows the device to operate over a wide supply voltage of 2.7 to 5V with typical current of 20 mA. GaAs pHEMT fabrication provides a combination of low DC power, low noise and high gain.

RFMW announces design and sales support for a GaN Transistor from Ampleon. The CLF3H0060-30U is a 30 Watt, unmatched, broadband, GaN-SiC HEMT transistor usable for both CW and pulsed, general purpose applications in frequency ranges from DC to 6.0 GHz. The device utilizes a thermally enhanced package with low thermal resistance providing excellent ruggedness. Designed for broadband operation, the CLF3H0060-30U features high efficiency. Large signal models in ADS and MWO are available for this RoHS compliant device.

RFMW today announced a global distribution agreement with Menlo Microsystems, Inc. (Menlo Micro), known for reinventing the electronic switch with its Ideal Switch™ technology. Under the agreement, RFMW becomes a franchised distributor for worldwide marketing and sales of Menlo Micro products derived from their Ideal Switch™ technology, including RF and general-purpose switches, RF subsystems and power relays. RFMW is a specialized distributor providing customers and suppliers with focused distribution of RF and microwave components as well as specialized component-engineering support.

“The exponential growth of Menlo Micro around the world requires a channel partner who recognizes the value of demand-creation, as well as global marketing, sales and logistical support,” said Lew Boore, SVP of WW Sales and Business Development at Menlo Micro. “After an extensive review of potential partners, we’ve selected RFMW which will be key to supporting Menlo Micro’s next major growth phase. We are truly excited about the synergies between RFMW and Menlo Micro which will benefit our customers worldwide.”

The Ideal Switch enables 99 percent reductions in size, weight, power consumption and impacts dozens of applications and markets including test and measurement equipment, power management systems and 5G networks which will in turn enable the electrification of everything: today’s rapid transition to electric and autonomous vehicles, advanced avionics, IoT appliances, robotics and more. The massive improvements enabled by the Ideal Switch are modernizing the market for RF and power switching and protection devices in the 21st century.

According to Steve Takaki, Executive Vice President at RFMW, “RFMW has long recognized the value that MEMS technology brings to certain RF and microwave applications. The advantages of small, surface mount products which are not only reliable but can handle high power with low insertion loss are an RF designer’s dream come true. That’s why we are incredibly excited to formally partner with Menlo Microsystems on a global distribution agreement. RFMW’s industry leading technical sales support and global logistics teams allow us to provide design engineers the latest technology, the Ideal Switch, for improved system designs in the rapidly growing communications and defense markets.”

What is an anechoic chamber?

Absent of reflection signals and electromagnetic emanation, an anechoic chamber (Figure 1) creates an ideal space for design engineers to test electronic components and devices. To eliminate external interference, anechoic chambers are manufactured with absorbing materials like ferrite tiles and conductive carbon. The resulting silence provides an opportunity to achieve precise measurements of device performance. Any electronic device design, either wired or wireless, is required to meet certification specifications. Regulation types vary by region and are government mandated.

What are the benefits of pre-compliance anechoic chamber testing?

Device pre-certification evaluation within an anechoic chamber ensures adherence in design schedule with integration of RF testing from the beginning of a development process. Considering the value of time and cost efficiency, pre-liminary guidance on the performance of a device is an essential benefit that pre-compliance testing also offers. Pre-compliance testing provides design engineers the advantage of the time to address design or performance issues before stepping foot into an official certification lab. Chambers at large commercial labs are often booked and have expensive hourly/shift rates. Designers can save hundreds to thousands by utilizing a pre-compliance chamber.

Where can I book a pre-compliance electronics test?

Part of the Exponential Technology Group (XTG), engineering consulting firm Connected Development (CD), offers in-house pre-compliance anechoic chamber testing. Having an in-house device testing chamber is a major asset in Connected Development’s comprehensive engineering service offerings. In fact, having this resource is extremely uncommon for design houses of their size. As a team of engineering experts, Connected Development is well-versed in pre-certification processes and can ensure a successful deployment without delay or fear. Connected Development’s anechoic chamber can conduct the following analyses:

• RF/Antenna performance testing
• Detailed current consumption analysis
• Custom automated test campaigns
• Software quality and robustness testing
• Design reliability testing
• Environmental and accelerated life testing
• Passive antenna pattern testing for design, matching, or trimming an antenna

What test and measurement equipment is needed to run an anechoic chamber test?

While Connected Development can assist design teams through pre-compliance testing processes, it’s important to note that cables, connectors, and adapters for anechoic chamber testing vary based on measurement type. RFMW is well-equipped to assist design teams in selecting appropriate test equipment required to begin device analysis in a pre-compliance chamber. Test frequency range is one of the determining factors in selecting connector size, type, and assembly. Manufacturers like Delta offer color-coded connectors according to frequency range for easy identification.

RFMW offers a broad selection of test and measurement solutions including cables, connectors, and adapters that are compatible with different frequency ranges. Experts at RFMW can help determine which connector solution is best for your unique application. Selecting the optimal cable connector is critical in ensuring accuracy of your anechoic chamber device test.
