HMC347C8
GaAs MMIC SMT HIGH ISOLATION SPDT SWITCH, DC - 8 GHz
Features
Isolation: 50 dB @ 2.5 GHz 36 dB @ 8 GHz
Insertion Loss: 2 dB Typical Non-Reflective Design Surface Mount Ceramic Package
General Description
The HMC347C8 is a broadband high isolation nonreflective GaAs MESFET SPDT switch in a nonhermetic surface mount ceramic package. Covering DC to 8 GHz, the switch features >50 dB isolation up to 2 GHz and >35 dB isolation up to 8 GHz. The switch operates using complementary negative control
voltage logic lines of -5/0V and requires no bias supply. This SPDT is an excellent replacement for the HMC132C8 SPDT.
