General Description
The HMC347 is a broadband non-reflective GaAs
MESFET SPDT MMIC chip. Covering DC to 20 GHz,
the switch offers high isolation and low insertion loss.
The switch features over 50 dB isolation at lower
frequencies and over 40 dB at higher frequencies due
to the implementation of on-chip via hole structures.
The switch operates using two negative control volt-
age logic lines of -5/0V, requires no Vee 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.
