HMC641A Overview
The HMC641A is a nonreflective, single-pole, four-throw (SP4T) switch, manufactured using a gallium arsenide (GaAs) process. This switch typically provides low insertion loss of 2.1 dB and high isolation of 42 dB in broadband frequency range from 0.1 GHz to 18 GHz. The HMC641A includes an on-chip, binary 2 to 4 line decoder that provides control from two logic input lines.
