Chip Scale Package MMIC DC-40 GHz 3 dB Equalizer: MEQ3-40CSP1 Datasheet

The MEQ3-40CSP1 is a compact, passive MMIC equalizer engineered for broadband applications requiring frequency-dependent loss compensation and gain flatness improvement.

Packaged in an ultra-small 1.5 mm CSP1 chip-scale surface-mount package, it supports extreme miniaturization while maintaining compatibility with standard solder reflow processes, making it an ideal choice for next-generation designs that demand reduced size, weight, and power (SWaP).

Operating from DC to 40 GHz, the MEQ3-40CSP1 provides positive slope equalization, addressing challenges such as amplifier gain roll-off or filter passband variations that can compromise system performance. It features a DC attenuation of 3 dB and delivers excellent broadband matching with a 26 dB return loss, ensuring minimal signal reflections and maintaining signal integrity across wide frequency spans.

The equalizer plays a critical role in improving the performance of broadband signal chains. In RF systems, it compensates for frequency-dependent losses, flattening system response and enhancing overall linearity. In high-speed digital systems, it can improve eye diagrams by equalizing frequency roll-off, leading to cleaner, more reliable data transmission. These capabilities make it highly versatile across applications in communications, radar, test and measurement, and advanced electronic systems.

By combining wideband performance, low insertion attenuation, excellent return loss, and an ultra-compact footprint, the MEQ3-40CSP1 offers a practical solution for engineers seeking to optimize performance in size-constrained, high-frequency designs. Whether equalizing filters, compensating amplifiers, or enhancing digital signal quality, this device delivers reliable, space-efficient equalization across demanding RF and microwave environments.
