The QPA1017D is Qorvo’s MMIC power amplifier operating from 5.7 – 7.0 GHz for C-band radar and satellite communications applications. Fabricated on Qorvo’s production 0.15 um GaN on SiC process, the amplifier produces 50 W of saturated output power with 21 dB of large-signal gain while achieving greater than 40% power-added efficiency.

Mini Circuits offers the CMA-83LN+ low noise MMIC amplifier operating from 0.5 to 8.0 GHz for sensitive, high-dynamic range receiver applications. The amplifier offers flat gain and a P1dB of 20.3 dBm at 2 GHz with a noise figure of 1.3 dB. It operates on a single 5 V or 6 V supply and is well matched f to 50 ohms.

Mini Circuits released the TSS-44+ monolithic amplifier operating from 22 to 43.5 GHz to be used in 5G applications. This surface mount, MMIC amplifier with shutdown feature fabricated using E-PHEMT technology and is a fully integrated 3-stage gain block up to 43.5 GHz with excellent active directivity.

The Qorvo QPA1022D is a MMIC power amplifier operating from 8.5 – 11 GHz for radar, electronic warfare, and satellite communications applications. Fabricated on Qorvo’s production 0.25 um GaN on SiC process, the amplifier produces greater than 4 W of saturated output power and 24 dB of large-signal gain while achieving greater than 45% power-added efficiency.

The CMPA2735075F is a gallium nitride (GaN) High Electron Mobility Transistor (HEMT) based monolithic microwave integrated circuit (MMIC) suited for civil and military pulsed radar applications. GaN has superior properties compared to silicon or gallium arsenide, including higher breakdown voltage, higher saturated electron drift velocity and higher thermal conductivity.



MMIc circuits are traditionally called “mimic” circuits. They are an abbreviation for Monolithic Microwave Integrated Circuit. These circuits are normal integrated circuits just like any chip except they operate on a specific frequency range. They operate in the microwave range of 300 mega hertz to 300 gig hertz.  MMIC circuits have a very small form factor. They typically contain numerous other circuits within them and are a form of hybrid. The main board is made from gallium arsenide and is mass produced by the millions. The IC itself is used in many applications from amplifications of low level noise and other microwave circuits.

MMIC have evolved over the years and as such much research has gone in to the making of new age chips. These new chips have been made to withstand huge cut off as well as increase the gain on the antennas that they are connected to. MMIC chips have reduced over the years and are now approximately 1% the size they used to be when they were first designed. These chips will further decrease in form factor from their current millimeter range into the pico meter range within a few years. The substrates materials that are currently supporting the build have also changed over the years and now include SiGE and GaN.

One thing to note is that the materials used in making these chips can be harmful to the environment if the byproducts of manufacturing are not properly disposed off.  In this category most governments have imposed laws on the disposal and incineration of chemical byproducts. The incineration processes totally any environmental issues.
