HMC347B

The HMC347B is a broadband non-reflective GaAs pHEMT SPDT MMIC chip. Covering 0.1 to 20 GHz, the switch offers high isolation and low insertion loss. The switch features over 52 dB isolation at lower frequencies and over 45 dB at higher frequencies due to the implementation of on-chip via hole structures. The switch operates using two negative control voltage logic lines of -5/0V, requires no Vee and has no current consumption. The switch operates down to 0.1 GHz. The chip features coplanar I/Os that allow 100% RF testing prior to delivery to the customer.
