The switch operates from 0.1 GHz to 20 GHz with an insertion loss of 1.7 dB and an isolation of 46 dB to 20 GHz due to the implementation of on-chip, via hole structures. The switch operates with two negative control voltage inputs (VCTL = - 5 V or 0 V), requires no supply, and has no current consumption. All electrical performance data is acquired with the RFx pads of the HMC347B connected to 50 Ω transmission lines via one 3.0 mil × 0.5 mil ribbon of minimal length. Rev. E Document Feedback...
