Our first contract was a 10 kW radar transmitter. Since then Delta-Sigma amplifiers have flown over Antarctic ice, sat on remote profiler sites, gone to sea, and run 24 hours a day on a foreign air-defense program since 1996. The list below is who we have built for. What follows it is what we built.
Delta-Sigma supplies U.S. Government and military customers, scientific agencies, aerospace primes, universities and research organizations, with concentrations across the AUSCANUKUS nations and Israel. These are organizations we have delivered solutions for.
Additional customers, programs and references are available under NDA. Several delivered programs cannot be listed here.
All marks are the property of their respective owners. Their appearance here indicates a delivery relationship, not an endorsement of Delta-Sigma, Inc.
Some of these are unclassified because the science was published. Some are here because the customer let us say so. The pattern across all of them is the same: it shipped, it worked, and it stayed working.
A modular amplifier system delivered for the Peace-Link air-defense program with the Taiwan Ministry of National Defense. It has been operational around the clock since 1996. The prime contractor's people joked that they could not make money on spares, because the customer did not think he needed any.
SAR sensing from aircraft flying 1,500 ft above the ice, resolving nearly 10,000 ft below it. The processing found a lake well beneath the Antarctic ice sheet that nobody knew was there. Cold, remote, power-constrained, and no chance of a service call, which is the environment our efficiency and reliability numbers were built for.
NASA selected Delta-Sigma for a wind profiler that has no equivalent anywhere else. Related work includes the SATURN amplifier family built for the JPL/NASA program and the BELLEROPHON sub-assembly for AirMOSS. We continue to support profiler infrastructure in the field, including installations outside the United States.
The THEIA family delivers 1.5× to 2.5× the output of the best-in-class competitor models in 20–50% less rack space: 1 kW, 2 kW and 2.5 kW all in 4U where competing chassis need 5U to 8U for less.
We originally delivered this amplifier at 84U. The refactor cuts the footprint 85% at the same output. The best competing approach still needs two 8 kW amplifiers and 42U. Alternatively, keep the original 84U bay and put roughly 100 kW in it.
The PEGASUS family (2 kW and 4 kW pulse at 449 MHz, 140–150 MHz and 400–460 MHz) is the backbone of profiler and sounder installations that sit unattended for years. Zero droop, fast rise times, non-existent ringing, and a highly linear response tailored for pulse radar waveforms of varying duty cycle.
MARISTAR-A8H puts 8 kW of multi-channel marine communications into 22U. ORION50 is a DICASS transmitter logic and control unit in an ARINC form factor. Both are examples of the same amplifier technology adapted to a very specific platform envelope and a very specific qualification path.
Research groups come to us when the instrument they want to build does not have an amplifier behind it yet. That work feeds back: the CENTURION 16 kW systems, the PROTOPHOS proton-debuncher sub-system and the KHIONE 4-channel polarimetric radar transmitter all started as somebody's requirement nobody else would quote.
A very low warranty return rate, over decades. Few returns in or out of warranty. That is a manufacturing and quality story, not a marketing one, and it is the single thing that has kept this customer list growing since 1995.
Breaking the Limits. Built on DSI.
A field-proven record across commercial, aerospace and government programs. We keep a wall of awards and we are still lengthening it.
Co-sited operations mean more emitters coupling RF between closely spaced antennas. Design integrity keeps that from contaminating anyone.
Which matters most exactly where service is hardest: mobile platforms, remote sites, and anywhere battery drain or power distribution is the real constraint.
A large library of modules and configurations adapts to multiple program requirements. Low risk on adaptation, and volume drives the cost down.
Field service and integration support, including international travel to site. In the unlikely event of a field failure, emergency response is part of the deal.
Australia, Canada, the UK, the United States and Israel. Domestic and international programs, supported globally.
Detailed past performance, program references and quality documentation are available on request, and under NDA where the program requires it.
Customers are also welcome to visit Riverside by arrangement and inspect any part of the operation, including automated assembly and burn-in.
