Device Overview
General Description
The MEQ12-7ASM passive MMIC equalizer QFN is an ideal solution for compensating for low pass filtering effects in RF/microwave and high speed digital systems. They provide positive slope from DC to 7GHz with DC attenuation options between 3 and 12dB. The unique design offers superior return loss to competitors. GaAs MMIC technology provides consistent unit-to-unit performance in a small, low cost form factor.
Features
- DC attenuation options from 3 to 12dB
- Typical Insertion Loss 1.1dB at 7GHz
- VSWR < 1.5:1 Over Entire Band
Applications
- RF Transceivers
- High-Speed Data
- Telecom
- Cable Loss Compensation
- Amplifier Compensation
