RF linear and nonlinear characterization

  1. Low cost network analyzer for reflection coefficient measurement and material characterization.
  2. Vector signal generation and analysis for RF modulated measurement.

Our capabilities lies in the generation of single and multiple Tone, modulated signals like QAM, OFDM, LTE, pulse shaping in baseband and transmission in analog domain. The testbed designed is capable of performing the measurement of active devices as well as passive devices.
