Marki Microwave MMIC Amplifier Product Families Decoded

Marki Microwave offers a variety of MMIC amplifiers for use in all areas of RF and microwave systems. We have MMIC amplifiers tailored for use as single-tone LO drivers, as well as high-linearity, low-noise gain blocks for direct integration into the signal chain. With so many options available, it can be challenging to quickly determine which amplifier or amplifier family is best suited for your application. This short guide highlights each of Marki’s microwave amplifier product lines, their primary applications, and key features and benefits.

Marki has four amplifier product lines: ADM, AMM, APM, and AKA. These three-letter codes identify the family to which an amplifier belongs and are easily recognized as the first three digits of the amplifier part number.

ADM

The first set of MMIC amplifiers we’ll discuss is the ADM family. The hallmark of the ADM family is its ease of use, primarily due to its positive-only bias, which eliminates the need for power supply sequencing when turning the amplifier on and off. ADM amplifiers come in a variety of frequency ranges up to 40 GHz and offer a balanced combination of output power, linearity, and low noise performance.

AMM

Next, we’ll discuss the AMM family of MMIC amplifiers. The AMM family features options optimized for operation above 40 GHz, primarily serving as single-tone LO driver amplifiers designed to drive the LO on Marki’s high-frequency passive mixers. This family requires a negative gate bias voltage, meaning power supply sequencing is necessary.

APM

Now, let’s look at the APM line of MMIC amplifiers. The APM line is distinguished as the lowest phase noise option. These amplifiers are GaAs HBT-based and require positive-only biasing, eliminating the need for power supply sequencing. The APM line can be driven hard into saturation and is optimized for driving NLTLs and T3 mixers that perform best with square-wave LOs.

AKA

Finally, we’ll discuss the AKA family. The AKA family of MMIC amplifiers consists of traditional gain blocks. AKA MMIC amplifiers operate from DC to 14 GHz, offer low-power operation, and provide stable gain versus bias. They require a single positive DC supply, minimal external components, and are available as bare die or in a very small 1.3 x 2 mm DFN package.
