GENERAL DESCRIPTION The HMC641A is a nonreflective, single-pole, four-throw (SP4T) switch, manufactured using a gallium arsenide (Ga As) process. This switch typically provides low insertion loss of 2.1 d B and high isolation of 42 d B 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. The switch operates with a negative supply voltage of - 5 V to - 3 V and requires two negative logic control voltages. All electrical performance data is acquired with the HMC641A that all RFx pads are connected to by the 50 Ω transmission lines via one 3.0 mil × 0.5 mil ribbon bond of minimal length. Rev.
