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.
