GENERAL DESCRIPTION
The HMC641ALP4E is a general-purpose, nonreflective, singlepole, four-throw (SP4T) switch manufactured using a gallium arsenide (GaAs) process. This switch offers high isolation, low insertion loss, and on-chip termination of the isolated ports.
The switch operates with a negative supply voltage range of −5 V to −3 V and requires two negative logic control voltages.
The HMC641ALP4E includes an on-chip, binary 2 to 4 line decoder that provides logic control from two logic input lines. The HMC641ALP4E comes in a 4 mm × 4 mm, 24-lead LFCSP package and operates from 0.1 GHz to 20 GHz.
