Overview
The HMC641ALP4E, manufactured by Analog Devices Inc., is a general-purpose, non-reflective, single-pole, four-throw (SP4T) switch. This device is fabricated using a gallium arsenide (GaAs) process and is designed to operate from DC to 20 GHz. It features high isolation, low insertion loss, and on-chip termination of the isolated ports. The switch includes an integrated 2 to 4 line decoder, which simplifies the control logic by reducing the number of required control lines from four to two. It operates with a negative supply voltage range of −5 V to −3 V and requires two negative logic control voltages.
