Product Details

The HMC345ALP3E is a broadband non-reflective GaAs MESFET SP4T switch in a low cost leadless surface mount packages. Covering DC to 8 GHz, this switch offers high isolation and low insertion loss. This switch also includes an on board binary decoder circuit which reduces the required logic control lines to two. The switch operates using a positive control voltage of 0/+5V, and requires a fixed bias of +5V.

* Blocking capacitors are required at ports RFC and RF1, 2, 3, & 4. Their value will determine the lowest transmission frequency.


This switch is suitable for usage in DC - 8.0 GHz 50-Ohm or 75-Ohm systems:

  • Broadband
  • Fiber Optics
  • Switched Filter Banks
  • Wireless below 8 GHz
