MMIC Amplifier Product Families Decoded

By Brian Baxter

Marki Microwave provides a versatile range of MMIC amplifiers tailored to diverse RF and microwave system needs. With four main amplifier product lines—ADM, AMM, APM, and AKA—each family is designed to meet specific application demands, from high-frequency signal driving to low-noise amplification.

The ADM line features amplifiers optimized for simplicity, requiring only positive biasing, which eliminates power sequencing and supports frequencies up to 40 GHz. These amplifiers offer a balanced mix of power, linearity, and low noise, making them versatile for various RF applications. The AMM line, on the other hand, specializes in high-frequency amplification, targeting applications above 40 GHz, particularly as single-tone LO drivers for Marki’s high-frequency mixers. The AMM amplifiers require a negative gate bias, necessitating careful power supply sequencing.

The APM series is distinguished by its low phase noise, making it ideal for applications demanding high signal integrity. Built on GaAs HBT technology, these amplifiers require only positive biasing, can drive into saturation, and are well-suited for NLTL and T3 mixers. Finally, the AKA line includes traditional gain block amplifiers operating from DC to 14 GHz. These amplifiers are compact, stable across bias settings, and require minimal external components, making them ideal for straightforward integration.

This organized lineup allows engineers to select the best amplifier for their specific needs, whether prioritizing frequency, noise performance, or ease of integration, ensuring optimal performance in complex RF and microwave systems.
