Nano Atomic Clock

Richard RHDC — Wed, 09 Nov 2016 10:05:05 +0000

Vectron announces the releases of the Nano Atomic Clock (NAC1) by its partner AccuBeat. The NAC1 utilizes the quantum physics principal of coherent population trapping (CPT) in a low power, small form factor, rubidium vapor cell to deliver aging rates of 1 ppb/year in a package that is one tenth the size of traditional rubidium, with an order of magnitude reduction in power consumption. Traditional rubidium vapor cell manufacturing techniques used in the production of the physics package ensure much longer term reliability of the product when compared to competitive products currently on the market.

Features

Aging: <3E-10/month, 1E-9 per year
Power Consumption: <1.2W
Supply Voltage: 3.3 VDC
Package: 32cc (41.1mm x 35.3mm x 22mm)
Temp Stability: ±1E-9 / -20^oC to 65^oC
Outputs: 10MHz, 1PPS; Input: 1PPS
RS232 interface for monitoring and control

Applications

ManPack Radio
SATCOM
Avionics
Seismic
UAVs

TDX1210 – GNSS Diplexer

Richard RHDC — Wed, 09 Nov 2016 11:09:18 +0000

The small form factor, high-performance GNSS diplexer are the latest addition to a comprehensive portfolio of GNSS filters supporting numerous single and multi-system architectures. These diplexers were developed to simplify RF frontend architecture for designers of high-performance GNSS receivers. By replacing several components including two SAW filters and several (typ. 3-5) discrete reactive matching elements, this drop-in 50ohm-impedance component greatly simplifies the design of dual-band GNSS frontends.

As challenging navigation tasks, such as Agricultural Automation, Construction and Mining, or Autonomous Vehicles continue to evolve and GNSS frontend systems are relied upon to achieve the centimeter-scale positioning accuracies, simplifying the design architecture of these systems by reducing overall component counts as well as footprint size will become increasingly paramount.
