Our solutions power critical systems across industries where precision and reliability are non-negotiable.
Especially in rural areas or under difficult reception conditions, regeneration of weak mobile signals is necessary for a stable mobile connection. Two-way amplifiers (uplink and downlink), also called repeaters, compensators, or boosters, are often used as relay stations for this purpose.
In our in-house PCB prototyping lab, multilayer PCBs with plated through-holes can be produced within just a few hours. The surfaces are gold-plated as standard for good long-term stability. The gold surface can be used for wire bonding.
We have considerable freedom in choosing the printed circuit board material. We apply a photosensitive layer to the materials and then process them. Mixed builds with different substrates are also possible, for example, Rogers combined with FR4.
Prototypes are often built from the substrate that will later be used in series production; this avoids the otherwise unavoidable retuning of the high-frequency circuitry when using a different printed circuit board material.
If desired, the boards can also be coated with a commercially available solder mask.
The layout data is either created with our own layout tools (Altium Designer, Eagle, KiCad), or Gerber or DXF data from the customer can also be processed.
The achievable assembly accuracies are comparable to those of volume manufacturers.
Based on the ARM® Cortex® microcontroller (STM32 Cortex M4), we offer a flexible solution for a wide variety of sensor applications. Signal conditioning, data acquisition, filtering, and processing of measured values are all performed on a single board. The software can be customized to meet specific measurement requirements.
The system shown here provides 18 inputs. 3 analog inputs can be sampled simultaneously and in phase (2.4 MSPS at 12-bit resolution).
The DSP functionality is also located on the Cortex® MCU and includes functions such as FFT, FIR and IIR filters, as well as other mathematical functions. UART, SPI, and an Ethernet interface are available for configuring external components and outputting the processed data.
Transitions from coaxial connectors such as SMA, SMB, MCX or N connectors to a microstrip or stripline must be designed with low matching losses.
It is often necessary to optimize the design or layout by means of a field simulation of the transition. This is typically done using a CST simulation.
Since the transition is also subject to mechanical stress, the mechanical connection of the plug or socket must be designed to be correspondingly robust.
Typically, test boards are created first, on which verification and optimization in the time and frequency domains are performed (TDR measurement technology, S-parameter measurement technology). Measurements up to 40 GHz or 25 ps time resolution can be carried out in-house.
The adjacent image shows the implementation of an SMA stripline connector. For good mechanical stability, the connector is soldered to the PCB all around.
