Electro-mechanical RF Switch Vs solid state RF Switch | Difference between Electro-mechanical RF Switch and solid state RF Switch
This page compares Electro-mechanical RF Switch Vs solid state RF Switch and mentions difference between Electro-mechanical RF Switch and solid state RF Switch.
Features | Electro-mechanical RF Switch | solid state RF Switch |
---|---|---|
Function | This switch type depend on mechanical contacts for switching. | This switch depend on solid state devices used for its operation. The solid state devices include PIN diode, GaAs FET or combination of both. |
Frequency range of operation | From DC | From MHz (solid state PIN diode), From KHz (hybrid-combined PIN and FET) |
Insertion Loss | Lower | Higher |
Return Loss | Good | Good |
Isolation | Good across all frequencies | Good at low end frequencies (FET) Good at high end frequencies (PIN diode) |
switching speed | in millisecond, it is slow in operation | in nanosecond, it is fast in operation |
settling time | < 15ms | < 1µs |
power handling capacity | Higher | Lower |
Life | Medium | Higher |
ESD immunity | High | Low |
Repeatability | Good | Excellent |
Sensitive | It is sensitive to vibration. | It is sensitive to RF power over-stress and temperature. |
