Device Overview
General Description
The MEQ20-20CSP1 is a passive MMIC equalizer CSP ideal for compensating for low pass filtering effects in RF/microwave and high speed digital systems. The MEQ20-20CSP1 provides 18.3dB positive slope equalization from DC to 20GHz with a DC attenuation of 20.3dB. The chip scale package allows for extreme miniaturization of the SMT footprint. The unique design offers superior 25dB return loss to competitors in an extremely small footprint. GaAs MMIC technology provides consistent unit-to-unit performance in a small, low cost form factor.
Features
- Small 1.5 x 1.5 mm package size
- DC attenuation of 20.3dB
- Typical Insertion Loss 2.0 dB at 20GHz
- Typical VSWR of 1.12 Over Operating Band
- Low SWaP
- This product embodies Marki Microwave's U.S. Pat. 11,869,858.
Applications
- RF Transceivers
- High-Speed Data
- Telecom
- Cable Loss Compensation
- Amplifier Compensation
