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.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.ApplicationsTest instrumentationMicrowave radios and very small aperture terminals (VSATs)Military radios, radars, and electronic counter measures (ECMs)Broadband telecommunications systems
