Why tunable matters
Modern systems must cover many bands and adapt to changing conditions. MEMS tunable capacitors and switched networks replace banks of fixed components with a single reconfigurable device, shrinking size and weight.
How MEMS works
MEMS devices use micromechanical elements to change capacitance or switch signal paths. They combine the low loss of mechanical switches with the small size of semiconductor fabrication.
Key advantages
- Near-zero insertion loss compared to solid-state alternatives.
- High linearity for demanding transmit paths.
- Low power consumption.
- Wide tuning range in a tiny footprint.
Typical applications
- Tunable matching networks for multi-band antennas.
- Reconfigurable tunable filters and phase shifters.
- Impedance tuning for mobile and aerospace radios.
What to evaluate
Check the tuning range, actuation voltage, switching speed, and lifetime cycle count. For defense and aerospace, also verify temperature and radiation tolerance. Browse our MEMS tunable devices with those criteria in hand.
