DESCRIPTION
Additional features include eye cross point adjustability, internal power sequencing circuitry and filtering, a bias port to apply a DC level to the output port, and the ability to apply a dither tone to amplitude-modulate the output data. This feature is critical for traditional modulator bias control loops. The differential limiting amplifier at the front end provides the user with a means to adjust the cross point of the output eye waveform. It also provides the subsequent gain stages with a constant amplitude signal, making the amplified output signal less sensitive to variations at the iT5082 input. Fabricated using GaAs pHEMT devices and thin-film passive components, the iT5082 exhibits excellent performance and reliability. The iT5082 is available in an SMA connectorized module. The primary heat conduction path is through the base of the module, so proper thermal management is required. Operating case temperature range is 0° C to 70° C. FEATURES
