The HMC347A is a broadband, nonreflective, gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT), single-pole, double throw (SPDT), monolithic microwave integrated circuit (MMIC) chip. The switch operates from 0.1 GHz to 20 GHz with an insertion loss of <2.0 dB and an isolation of >40 dB due to the implementation of on-chip, via hole structures.The switch operates with two negative control voltage inputs (VCTL= −5 V/0 V) and requires no supply. All electrical performance data is acquired with the RFx pads of the HMC347A connected to 50 Ω transmission lines via one 3.0 mil × 0.5 mil ribbon of minimal length.ApplicationsTest instrumentationsMicrowave radio(s) and very small aperture terminals (VSATs)Military radios, radars, electronic counter measure (ECMs)Broadband telecommunications systems
