Model E9120H and E9120HT Economical Hermetically Sealed High-Speed SPDT Switch

Application Notes for RF Switches
The Model E9120H is a hermetically sealed, low cost high speed, SPDT PIN diode switch with integrated driver. The switch can be used as a drop-in module. The switch operates over the instantaneous frequency range of 1 to 18 GHz. The Model E9120HT is a non-reflective version of this switch.
  • Low cost
  • Frequency range: 1 to 18 GHz
  • High speed: 10nsec rise fall times
  • Isolation 60 dB
  • Reflective and non-reflective models
  • Low VSWR and Insertion loss
  • Low in-band video leakage
  • Hermetically sealed
  • Low profile
  • Can be used as a drop-in module
