Overview
The HMC347ALP3E is a broadband high isolation non-reflective GaAs pHEMT SPDT (Single-Pole Double-Throw) switch manufactured by Analog Devices Inc. This component is housed in a low-cost leadless QFN (Quad Flat No-Lead) surface mount plastic package. It operates over a wide frequency range from DC to 14 GHz, making it suitable for various high-frequency applications.
The switch is designed to offer high isolation and low insertion loss, which are critical parameters for maintaining signal integrity in RF and microwave systems. It features complementary negative control voltage logic lines of -5/0V and does not require a bias supply, simplifying its integration into complex systems.
