0.3-18GHz Upconverter Converter Module with 2GHz Instantaneous Bandwidth

0.3-18GHz Upconverter Converter Module with 2GHz Instantaneous Bandwidth. 0.3-18GHz Coverage with Direct and Converted Paths: a 0.3-2GHz direct path plus a 2-18GHz conversion path fed from a 3.6GHz IF, in a dual-superheterodyne architecture. Wide 2GHz Instantaneous Bandwidth: supports wideband waveforms with 2dB flatness over any 2GHz window and 3.5dB across the full 0.3-18GHz range. Fine 0.5dB-Step Attenuation over 60dB: an RF digital attenuator spanning 1-60dB in 0.5dB steps gives precise control of output level. Built-in Calibration Coupling Path: a 20dB calibration coupler operating across 0.3-18GHz supports built-in self-test and system calibration. Strong Filter Rejection in a Compact Module: 55dBc rejection at 2.6GHz (direct path) and at 2.2/5GHz (converted path), in a 123.4x26.8x9mm / 90g housing.
