The wideband, high gain digital amplifier module is a low noise, modular device requiring only +/-5 V supplies. It is optimized for the amplification of low-level digital data. Input signals with a Full-Scale Range (FSR) of 3 mV are amplified to X750 mV, a level suitable for RSFQ logic to TTL or ECL decision-circuit comparators.
Features
- True DC coupled precision amplification to 2.5 GHz
- Fixed high gain: 48 dB
- Input and output matched to 50 Ω
- Low noise figure: 1.7 dB
- Excellent flatness with positive gain slope equalization
- Excellent phase linearity for pulse work
- Total power consumption: 750 mW maximum
Applications
