Product Details

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.

Applications

  • Test instrumentations
  • Microwave radio(s) and very small aperture terminals (VSATs)
  • Military radios, radars, electronic counter measure (ECMs)
  • Broadband telecommunications systems

Design Tools

ADIsimRF

ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
