HMC347 / HMC347C8 / HMC347G8 / HMC347LP3
SPDT Nonreflective, High Isolation Switch Chip, SMT, and Hermetic SMT, DC to 20 GHz
The HMC347 is a broadband nonreflective GaAs MESFET SPDT MMIC chip and a broadband high isolation nonreflective GaAs MESFET SPDT switch in an 8-lead glass or metal (hermetic) surface-mount package or a low cost leadless QFN surface-mount plastic package. Covering DC to 20 GHz, the switch offers high isolation and low insertion loss. The switch features more than 50 dB isolation at lower frequencies and more than 40 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 −5/0 V, requires no Vee and no bias supply, and has no current consumption. The switch operates down to DC. The chip features coplanar I/Os that allow 100% RF testing prior to delivery to the customer. This SPDT is a good replacement for the HMC132G7 SPDT.
