Optical spectrum analyser MS9740B reduces test time for laser diode production

Tue, Jul 18, 2023

Contributing to improved laser diode chip production efficiency, Anritsu has introduced the measurement function MS9740B-020 for the optical spectrum analyser MS9740B model. It evaluates a pulsed laser diode chip, reducing the test time and contributing to improved production efficiency of high power laser diode chips, said the company.

Laser diode chip manufacturers and optical equipment vendors evaluate the optical spectrum of chips during manufacturing. Market demand for high power laser diode chips is driven by higher communication bit rates and longer lidar detection ranges.

There are also new use cases, such as external laser small pluggable (ELSFP) modules for co-packaged optics applications, which are expected to accelerate demand. The continuous wave (CW) output from a high power laser diode chip is subject to power drift and wavelength shift as the chip temperature rises. This is prevented by suppressing the temperature rise by using pulsed laser diode chips. Currently, testing of pulsed laser diode chips during production takes longer because an external trigger signal is required to synchronise with the pulsed laser diode chip.

The MS97040B-020 is rugged in design and reduces tact time for pulsed laser diode chips and accelerates optical spectrum evaluation by eliminating the need for a trigger signal, explained Anritsu.

It also assures measurement reproducibility for even high power laser diode chips, added the company with measurement reproducibility of ±1.4 dB for side mode suppression ratio (SMSR). Low SMSR variation improves the chip yield and helps production efficiency.

Anritsu has been providing communications test and measurement solutions for 128 years. Anritsu’s philosophy engages customers as true partners to help develop wireless, optical, microwave/RF, and digital solutions for R&D, manufacturing, installation, and maintenance applications, as well as multi-dimensional service assurance solutions for network monitoring and optimisation.

East Coast Microwave adds wide axial mating blindmate RF contacts

Tue, Jul 18, 2023

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.

Powell Electronics is a specialist at high reliability, harsh environment connector design, manufacturing and supply chain. In the USA, Powell has 70,000 square feet of connector manufacturing capabilities at its Swedesboro, New Jersey facility, which is certified to ISO9001 and AS9100.

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

Tue, Jul 18, 2023

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.
