Custom MMIC Announces Two Wideband Driver Amplifiers


Ranging from 2 to 9 GHz new GaAs MMICS offer high gain and high linearity

Custom MMIC, a US developer of monolithic microwave integrated circuits (MMICs), has added two new packaged driver amplifiers to its expanding product offerings, the CMD232C3 and the CMD231C3.

The  CMD232C3 GaAs MMIC driver amplifier functions from to 2-9 GHz and delivers over 15 dB of temperature stable gain with an output 1 dB compression point of 17 dBm, and an output IP3 of 23 dBm.

With this device's high linearity in a compact 3x3 mm package, these amplifiers serve for military, space and communications systems. They require a single 5V positive supply and supply current of only 90mA. The CMD232C3 is a 50 ohm matched design to eliminate the need for external DC blocks and RF port matching. The amplifier is a replacement for the Celeritek CMM-2, now in packaged form.

Offering wideband performance with a low current consumption, the CMD231C3 also uses GaAs MMIC technology to deliver over 14.5 dB of temperature stable gain and have a supply current of only 45mA.

The amplifiers requires a single 3 to 8V positive supply, to simplify the design process. It is offered in a 3x3 mm leadless surface mount package. Output 1 dB compression point is +13.5 dBm, with an output IP3 of 23.5 dBm.

The CMD231C3 is a 50 ohm matched design which eliminates the need for external DC blocks and RF port matching. The amplifier is a replacement for the Celeritek CMM-9, now in packaged form. It is suited for military, space, and communications systems where small die size and high linearity are necessary.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
