Models E9140H and E9140HT Economical Hermetically Sealed High Speed SP4T Switch

Application Notes for RF Switches

The Model E9140H is a hermetically sealed, low cost high speed, SP4T 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 E9140HT is a non-relective version of this switch.
