Product overview and engineering role
The SimtoLink millimeter-wave array antenna module puts a multi-element radiator and the RF feed in one assembly. It is for sensing, private-network radio, and test gear that needs beamforming or a high-gain narrow beam, and it mates to a millimeter-wave transceiver or an IF subsystem.
The table lists typical electrical ratings. Channel count, scan range, and calibration data depend on the order code. For integration, use the hardware specification and the phase and amplitude consistency report.
Reliability and field fit
A millimeter-wave link is sensitive to mounting tolerance, radome dielectric, and metal near the aperture. Thermal expansion and vibration also shift phase, so leave room in the design for calibration and temperature compensation.
Strong-target sidelobes and multipath disturb angle and range. SimtoLink recommends a joint OTA and near-field tune in the real scene, and a pattern record at each mounting height.
Key hardware parameters
RF and mechanical ratings below are for a typical build, for selection and for tender clauses. For another millimeter-wave frequency, channel count, or scan method, ask SimtoLink for the hardware specification and the installation and commissioning guide. Order codes in the family can differ; the nameplate and the documents shipped with the unit govern.
| Parameter | Specification | Notes |
|---|---|---|
| Band | 24.0～29.5 GHz and others | As ordered for the target application |
| Gain | 10～25 dBi | Depends on element count and beam |
| VSWR | <2.0 | Typical aperture |
| Polarization | Linear / dual polarization | Matches the transceiver definition |
| Impedance | 50 Ω | Microstrip or connector, depending on the build |
| Power | Limited by the chip and cooling | EIRP must stay within the rules |
| Construction | Array plus radome | Calibrate the dielectric effect on the beam |
| Interconnect | Millimeter-wave coax or board-to-board | Tight tolerance and shielding |
| Operating temperature | -40～85 ℃ | See the specification |
| Mounting | Bracket and precision alignment | Keep a calibration step |
Typical applications
Four common deployments, for solution design and for judging return on investment:
Perimeter and security radar
A narrow beam raises angular resolution, and edge compute turns the return into a point cloud or a track.
Traffic and in-cabin sensing
In-cabin and roadside short-range radar is tight on space; the array module is straightforward to put on a custom bracket.
Laboratory OTA
Anechoic chambers and end-of-line stations need consistency spot checks and calibration.
Private-network and backhaul trials
Point-to-point or sector prototypes can be proven faster, so the RF subsystem iterates in fewer loops.
Installation, grounding, and maintenance
- Torque the fasteners and use the locating pins so the array does not warp and shift phase.
- Check radome material and thickness against dielectric constant. Do not swap the plastic parts on your own.
- Keep multi-channel feeds the same length, and check port marks against transmit and receive once.
- Remeasure VSWR and gain at the key angles before and after high and low temperature tests, and file the batch record.
- Use ESD and dust control when the module is opened on site so the patch cavity stays clean.
Ordering, documentation, and support
SimtoLink supplies the hardware specification, outline drawings, a wiring table, and example projects. Volume orders can include sample review and inspection at the plant. Warranty and calibration follow the contract and the papers packed with the module.
