East Coast Microwave adds wide axial mating blindmate RF contacts

East Coast Microwave, a subsidiary of Powell Electronics has added the PkZ series blindmate RF contacts from Phoenix Company of Chicago to its portfolio. According to East Coast Microwave, the contacts have the widest available axial mating tolerance currently available.

They have a constant impedance up to a .09 inch axial mating tolerance, which enables the contacts to accommodate large radial and axial misalignment tolerances found in modular applications, for example, in aerospace and vehicle communication systems, test systems, radar systems and UAV (unmanned aerial vehicle) systems.

The design of the high performance and reliable PkZ series contacts is credited for the low mating forces and constant impedance even as differences in mating profiles or gaps are created in the mating interface. These characteristics eliminate conventional and elaborate methods to overcome mating gaps, such as an internal spring, explained East Coast Microwave.

The components are available as MIL-DTL-38999 size 12 RF contacts for a frequency range from DC up to 40GHz (178 series), MIL-DTL-38999 size eight RF contacts for low loss cable for a frequency range from DC up to 32GHz (78 series) and ARINC microwave size eight coax contacts for ARINC connectors (600 series) for a frequency range from DC up to 32GHz (68 series). They are suitable for use with a wide range of connector housings including D-subs, high density D-subs, DIN 41612, four-position inserts, ARINC, MIL-DTL-38999 as well as custom housings.

East Coast Microwave is a subsidiary of Powell Electronics, the supplier of connectors and more for high-rel applications including defence, aerospace and industrial.

Infineon claims 1Mbit automotive-qualified serial F-RAM is an industry first

Infineon claims to offer the industry’s first 1Mbit automotive-qualified serial F-RAM. It has introduced two ferroelectric RAM (F-RAM) devices in 1Mbit and 4Mbit densities. The 1Mbit (CY15B201QN-50SXE) and 4Mbit (CY15B204QN-40SXE) are intended to meet demand for specialised data logging memories that instantly capture and reliably store critical data for decades and which are used in automotive event data recorders (EDRs).

The two F-RAMs are AEC-Q100 Grade 1-qualified and support an extended temperature range of -40 to +125 degrees C. They join Infineon’s portfolio of automotive F-RAM products ranging from 4kbit up to 16Mbit densities. The two new F-RAM devices have fast and highly reliable read/write performance at speeds up to 50MHz in SPI mode and up to 108MHz in quad SPI mode. They also have an endurance performance of 10 trillion read/write cycles to support data logging at 10 microsecond intervals for over 20 years.

Accounting for the increased demand, Ramesh Chettuvetty, vice president RAM Solutions at Infineon said that automotive industry is specifying the use of high-reliability non-volatile memories in airbag safety systems, along with engine control and battery management systems. “The demand for memory densities tailored to specific use cases has grown as the number of applications requiring data logging have increased,” he said.

The zero delay write capability of Exceleon F-RAM allows system data to be captured and recorded up to the last instant before an accident or other user-defined trigger event. Both new F-RAM devices operate from 1.8V to 3.6V and are supplied in a standard eigt-pin SOIC package. Infineon confirmed that its F-RAM is designed to retain data for more than 100 years after loss of power.

Infineon’s CY15B201QN-50SXE (1Mbit) and CY15B204QN-40SXE (4Mbit) Exceleon Auto F-RAM devices are now in volume production. Infineon also expects to release the quad SPI interface version of both devices by the end of this year.

TiePie releases instrument to wirelessly synchronise multiple oscilloscopes

The WCMI-8 is a long range wireless multi instrument synchronisation module, capable of operating over 400m. It allows multiple scopes to be combined into a single instrument, said Dutch company, TiePie Engineering.

The WCMI-8 module can operate with the WiFiScope and Handyscope series 5 and 6 instruments. The WCMI-8 module is placed on the extension connector at the rear of each oscilloscope and the multi-channel oscilloscope software automatically

detects how many instruments are equipped with a WCMI-8 module. All detected oscilloscopes, connected via WiFi, LAN or USB, are combined to a single oscilloscope with a total number of channels that equals the sum of the number of channels of the detected oscilloscopes. The WCMI-8 module has an internal automatic time synchronisation system that takes care that all sample clocks of the oscilloscopes are synchronised. When a trigger occurs on one of the selected channels, all oscilloscopes will be triggered simultaneously and all signals will be synchronously visible on the display.

The wireless multi instrument synchronisation modules can be used both indoors as in the open field. They have a built-in RSSI meter to check the receive signal strength of each module.

For synchronous measurements at multiple locations that are up to several hundred meters apart, or fully galvanically isolated from the computer and each other, TiePie recommends using the WCMI-8 module, in combination with a TiePie engineering oscilloscope. High speed sampling at 100 Msamples per second and 16bit high resolution measuring are supported by the WCMI-8 module. As there is no need for long cabling between the scopes and the computer and with no complicated setup. TiePie said installation is simple and hassle free installation.

Founded in 1987, the Dutch company TiePie Engineering manufactures computer controlled test and measurement equipment, such as WiFi, LAN and USB pscilloscopes, arbitrary waveform generators, function generators, spectrum analysers, protocol analysers, data loggers and multimeters. Products offer features such as real time SureConnect connection testing, SafeGround protection and combining multiple instruments using TiePie’s CMI bus. TiePie’s compact oscilloscopes, function generators and other data acquisition products are used worldwide in many markets, including industrial process automation, automotive test and measurement, service departments, medical applications, research centers and educational institutes.
