Overview
The HMC547LC3 is a general-purpose broadband high-isolation non-reflective GaAs MESFET SPDT (Single-Pole Double-Throw) switch, manufactured by Analog Devices Inc. This switch is housed in a ceramic 3x3 mm leadless surface mount package. It operates from DC to 28.0 GHz, offering high isolation and low insertion loss, making it ideal for various high-frequency applications. The switch is controlled by complementary negative control voltage logic lines of -5/0V and does not require a bias supply.
