Recently launched by DLI is the V Series, Single Layer Capacitor (SLC).  This series was designed to provide higher capacitance in a smaller footprint. The wire bondable range is ideal for power applications where excellent high frequency response is a prerequisite. This, together with the small footprint of just 0.03”/0.77mm square, allow for high density mounting.  Excellent in high frequency characteristics compared with general purpose MLCC’s, the impedance of this product becomes lower at high frequencies.  High capacitance, X7R dielectric temperature stability, and gold termination, completes the spec for DC Blocking, RF Bypassing, Filtering, Tuning and Coupling applications. RoHS compliancy is standard.

DLI’s application of precision thin film fabrication with integrated resistors, coupled with high permittivity ceramic materials, lead to a host of components for RF and Microwave applications to provide a high performance and repeatable design solution. The company has a lineup of cataloged and bespoke products such as Power Dividers, Couplers, Bandpass/Lowpass Filters and Xtreme Broadband Blocks.  Stand 177 will have specialized staff on hand to discuss specific products and applications that engineers may care to bring along.

Positive Bias Tech Brief - Eliminating Complex Bias Sequencers and Negative Voltage Supply

Custom MMIC is proud to announce a new technical brief illuminating our progress in eliminating complex bias sequencers and negative voltage supply.

Experts at Custom MMIC have been exploring the use of enhancement mode pseudomorphic high-electron-mobility-transistors (E-pHEMTs) in monolithic microwave integrated circuits (MMICs). This is a promising technique, for it may directly address a well-known design challenge. Specifically, that of sequencing in amplifier biasing.

The savings generated by removing the sequencer can be enormous. The use of E-pHEMT devices by designers of power amplifiers (PAs) and low noise amplifiers (LNAs) is in its infancy, as such devices have only recently been made available from a number of semiconductor manufacturers. However, Custom MMIC has been a pioneer in this area and currently offers dozens of standard, off-the-shelf PA and LNA components built with E-PHEMT technology. Not only can E-pHEMT amplifiers reduce cost and complexity, they can also improve performance. By definition, this is a win-win situation.

V2V and V2X automobiles and infrastructure roll out

Courtesy of u-blox by Patrick Mannion (Technology Analyst and Writer)

Read full article here:

The necessary elements of high‑level autonomous vehicles are starting to roll out as GM deploys Vehicle‑to‑Vehicle (V2V) systems in its vehicles, while Vehicle‑to‑Everything (V2X) test beds begin in Tampa, New York, and Wyoming.

It’s finally started: Automotive giant GM has begun V2V deployments with the rollout of dedicated short range radio (DSRC) in its 2017 Cadillac CTS models. The vehicles will be able to transmit and receive simple messages about location, heading and speed, over distances of up to 1000 feet at a rate of 10 messages per second, that is one message every 100 msec.

Per the original intent of V2V, Cadillac’s system allows vehicles to alert drivers of other vehicles to potentially hazardous situations ahead, giving them additional time to react. Common hazardous scenarios that prompt alerts are hard braking, slippery conditions and disabled vehicles. Drivers can also customize alerts to show in the instrument cluster and available heads‑up display.

Also, multiple V2V‑equipped vehicles create an ad hoc wireless network that allows for the transfer of information without relying solely on sight lines, good weather conditions or cellular coverage (Figure 2).

On the infrastructure side, shortly after Cadillac made its intentions known, both the Tampaand Wyoming Connected Vehicle (CV) Pilot Deployment Program websites went live, joining New York City’s program. The three locations were selected by the US Dept. of Transportation to receive a collective $45 million in funding to initiate a Design/Build/Test phase for its CV program. The premise of the program is that connected vehicles could save lives, enhance productivity, reduce vehicles’ environmental impact, and transform public agency operations for the better.

Each of the three sites have already spent 12 months of the 50‑month program preparing a deployment concept for a fast roll out (Figure 2). Now the program is in Phase 2, which involves designing, building, and testing the complex deployment of integrated wireless in‑vehicle, mobile device, and corresponding roadside technologies. This began in September and has been assigned a 20‑month time frame. The remaining months, or Phase 3, will be occupied with the maintenance and operation of the pilot programs.

DoT CV Pilots Deployment Program

Figure 2. The DoT’s CV Pilots Deployment Program has selected Tampa, New York, and Wyoming as pilot sites. All have completed Phase 1 concept development activities and have entered Phase 2 – Design/Deploy/Test. (Image source:

The program participants already have the benefit of 75 MHz of spectrum in the 5.9‑GHz band. This was set aside in 1999 by the FCC, explicitly for the use of intelligent transportation systems (ITSs). The spectrum is however allocated differently per region. For example in Japan, they operate DSRC in 720 MHz band. How that spectrum is used is up to the technologists and the regulatory bodies.

To help take advantage of the spectrum and support the development of ITS applications, the IEEE 802.11p amendment to the 802.11 standard was implemented for wireless access in vehicular environments (WAVE). Among other things, it defines the exchange of data between high‑speed vehicles and between vehicles and infrastructure (V2I).

The critical aspects of this communication include latency and signal processing time, especially as designers and automotive engineers consider moving to Level 4 and eventually Level 5 autonomy. Let’s use an example to show the importance of response time.

A vehicle moving at 65 mph covers 95.33 feet (29 meters) in 1 second. In the case of the GM Cadillac CTS, it has a wireless communications range of almost 1000 feet (305 meters), so it has a 10‑second window in which to respond. If that response means stopping as quickly as possible, that might take up to 400 feet (122 meters) to do safely, from 65 mph. Subtracting that 400 feet leaves only 6 seconds for the vehicles to communicate the nature of the upcoming incident to allow it to stop in time. Factor in non‑line‑of‑sight issues, the potential for RF interference and possible latencies at the application layer, and the importance of minimizing any delays becomes clear.

Right now, the 2017 Cadillac CTS is the only vehicle on the market with V2V built in, so it can only talk with other Cadillac CTS’s. This of course limits the usefulness of the feature, so Cadillac is not charging for it, for now. However, as more vehicles get deployed, and the infrastructure gets developed and expands beyond Tampa, New York, and Wyoming, the V2X functionality will become more useful, and valuable. Much like any communications network, it will follow Metcalfe’s Law and become exponentially more valuable the number of nodes are added.

In the meantime, Cadillac is eager to work with any company, or country, looking to roll out DSRC. It may also soon have V2V companions, as Chrysler and Ford have already indicated their intent to roll out V2X technology. Volkswagen also announced recently that it would deploy DSRC technology in new vehicles as of 2019.
