· Designs24-SMP to MicroD25 adapter
We have designed a microD25 to 24 SMP adapter. Enclosure Au-plated copper. M3 mounting holes at the sides. Ask for different gender, orientation, rf connector, shape or any other feature.
· DesignsMounting brackets for cryogenics
We provide Au-plated copper mounting brackets in three different sizes. Please see our brochure
· DesignsCryogenic filter with 940 nF capacitors
We designed and manufactured cryogenic RC filter using large 940 nF capacitors. These models are available for both pairwise (PW) and ground-referenced (G2) two-stage filters.

24-SMA microD25 adapter
We have designed a microD25 to 24 SMA adapter. Enclosure Au-plated copper. M4 mounting holes at the back. Ask for different gender, orientation, rf connector, shape or any other feature.
· DesignsSMP RC-filter 8 channel
An 8-channel 2-stage RC-filter was designed and built. Size 50 mm x 100 mm x 8 mm.
· DesignsSome custom breakout boxes
A) Breakout box with BNC, individual RC filtering and grounding options. B) Breakout box with SMA connectors, two selectable RC filter options (F1/F2) and grounding switch
· DesignsBoBoX with selectable RC filters
We have built a BNC breakout for Fischer-24 pin connector with selectable RC filters. The filter takes place between pairs of twisted pair lines (1-2, 3-4, ). It is possible to disable filtering if needed.
· DesignsMicro-D25 adapters
We design and manufacture Micro-D25 adapters to various connector types (SMA, SMP, MCX, nano-D etc) or for direct soldering. The adapters can be single block units with all input/output connectors in single enclosure or combinations of micro-D connector, shielded cable and output connector enclosure. Aluminum enclosure as standard, Au-plated copper upon request.
· DesignsSMA connector panel
Simple and slim 19-inch wide and 1U high aluminum panel with 40 SMA feedthru connectors. We can also modify panel to house different connectors according to your needs.
· DesignsNew Therma filters designed
We have introduced new Therma filter models with more versions and improved EMI shielding. Please take a look at the Therma (cryogenic RC filters) pages.
· DesignsExchangeable sample holder for electron pump devices
We have designed and manufactured cryogenic and non-magnetic sample holder with three rf connectors (SMP) and multi-pin dc connector (Omnetics, 21 lines). The design work was made in collaboration with e-Si-AMP consortium consisting of leading metrology institutes (www.e-si-amp.eu). The holder has duplicate dc connector for grounding. This makes it possible to transport sensitive samples between Read more about Exchangeable sample holder for electron pump devices[ ]
· DesignsAutomatic battery switch
We have updated the earlier BattSwitch and added automatic swapping every 12, 24 or 48 hours. By moving chargers outside the unit, the newest design is capable of producing four uninterruptible voltages. Thus, one can e.g. build up to +/-24 V regulated voltage supply. Preliminary manual available here.
· DesignsSmall SMP sampleholder
Upon customer s request, we designed and built a small sampleholder with non-magnetic SMP connectors. The size of the gold-plated copper or aluminum holder is 30 mm x 30 mm. It is easy to customize this design to fit different number of connectors or other features.

Frequency and pulse distribution amplifier available
We have built 1:8 frequency and pulse distribution amplifier FDA/PDA according to open hardware design available at Open Hardware Repository. More information available also there. The amplifier is designed for applications in time frequency metrology such as 1PPS/10MHz signal distribution from atomic clocks, GPS/GNSS-disciplined oscillators, or other precision timing applications (e.g. PTPv2/White Rabbit networks). Read more about Frequency and pulse distribution amplifier available.
· DesignsBattery swap unit
We have designed and build a battery swapping electronics BattSwitch that is based on our earlier uninterruptible battery source. BattSwitch can swap between 1-6 battery pairs and in addition it can contain linear voltage regulators to provide a stable and constant uninterruptible voltage supply for e.g. preamplifiers. Swapping can be controlled both manually and user-specified Read more about Battery swap unit[ ]

SMA and BNC boxes
Nord Cryo BNC (or SMA)-box is a BNC (or SMA) jack-to-jack interconnecting box with pads for surface-mount components (size 0603) inside the box. Minimum order quantity 5 boxes. Please ask for a quotation. SMA Box. Length without connectors 35.0 mm (with connectors 50.6 mm). Width 15.1 mm, height 10.2 mm. SMA Box opened. BNC box has Read more about SMA and BNC boxes[ ]
· DesignsUninterruptible battery power supply
We have designed and built an eternal battery power supply unit (PSU). In this 8-channel uninterruptible PSU, each output channel contains two batteries and a charger. One of the batteries is connected to actual output and the other is being charged. An intelligent relay electronics swaps the batteries within few milliseconds and a large capacitor Read more about Uninterruptible battery power supply[ ]
