DS3800NGTA1F1E | Replacement for DS3800NGTA

Description

Product Introduction

The DS3800NGTA1F1E is the aerospace-grade version of the general-purpose transceiver adapter—the NGTA built for installations where radiation tolerance, high vibration, and extreme reliability are all required. The suffix tells the story: the first “1” indicates a hardware revision with improved signal conditioning. The “F” specifies aerospace-grade components with radiation hardening and 100 krad tolerance. The second “1” adds enhanced diagnostic features. The final “E” is the environmental package: triple-layer conformal coating with ceramic-reinforced topcoat, hermetically sealed components, and MIL-STD-810G certification with 100g shock/15g RMS vibration tolerance. This board was designed for the most extreme aerospace and high-altitude applications.

The ceramic-reinforced topcoat provides abrasion resistance. The radiation hardening protects against high-altitude and space-adjacent radiation environments. Compare this to the NGTA1E1D (military-grade, no radiation hardening). The 1F1E adds radiation hardening, the ceramic topcoat, and higher shock/vibration tolerance.

Frequently Asked Questions (FAQ)

What makes the “F” suffix different from the “E”?
The “F” suffix adds aerospace-grade components with radiation hardening and 100 krad tolerance. The “E” suffix is military-grade without radiation hardening. The “F” is designed for radiation-prone environments; the “E” is for standard military-grade applications.

What’s the ceramic-reinforced topcoat?
The third layer of conformal coating contains ceramic micro-particles that resist scratching and abrasion. This protects the board during maintenance in tight cabinets where tools or cable bundles might contact the PCB. The ceramic topcoat also provides slightly better salt-spray resistance.

What’s the radiation event LED?
The Radiation Event LED indicates that the board has detected a radiation event. The board logs radiation events and can recover from radiation-induced single-event effects. This is a feature of the “F” suffix.

Do I need to upgrade my DMP firmware for the enhanced diagnostics?
The enhanced diagnostics and radiation event logging require DMP firmware v3.0 or later. We can provide the firmware EPROMs if you need them.

How is the NGTA configured?
The NGTA is configured via jumpers on the board or through firmware settings. If you’re replacing a failed NGTA, photograph the jumper settings before removing the old board.

Can I hot-swap this board?
No. Mark IV backplanes are not hot-swappable. The 1F1E has 6 securing screws—make sure they’re properly engaged before powering up.

What’s your warranty and lead time?
We stock the NGTA1F1E in limited quantities. Lead time is 2-3 business days. We offer a 2-year warranty. We test every board with a 48-hour burn-in, a thermal cycle (-55°C to +85°C), a vibration test on our shaker table, and a full diagnostic verification. The test report is included.

Is this board compatible with the Mark VIe?
No. This board is for Mark IV systems only. The backplane architecture is different.
