Device Overview
General Description
The MEQ4-60ABH passive MMIC equalizer is an ideal solution for compensating for low pass filtering effects in RF/microwave and high speed digital systems. This equalizer provides 2.6 dB positive slope equalization from DC to 60 GHz with a DC attenuation value of 4 dB and a 50-ohm match maintained over the entire operating range. GaAs MMIC technology provides consistent unit-to-unit performance in a small, low cost form factor. Contact the factory for connectorized versions of our other MEQ products.
Features
- DC attenuation of 3.9 dB
- Typical Insertion Loss of 1.6 dB at 60 GHz
- Typical 25 dB Return Loss over the entire band
Applications
- RF Transceivers
- High-Speed Data
- Telecom
- Cable Loss Compensation
- Amplifier Compensation
