Overview
The HMC547ALP3E, produced by Analog Devices Inc., is a general-purpose broadband high-isolation non-reflective GaAs pHEMT SPDT (Single-Pole Double-Throw) switch. It is packaged in a low-cost leadless QFN (Quad Flat No-Lead) surface mount plastic package, measuring 3x3 mm. This switch operates over a wide frequency range from DC to 20 GHz, making it suitable for various high-frequency applications. It features high isolation and low insertion loss, with no bias supply required, and uses complementary negative control voltage logic lines of -5/0V.
