Microsemi Unveils Six Wideband MMICs

DC-26 GHz LNAs and switches suit radar, electronics warfare, and test & measurement applications

Microsemi has announced six new monolithic microwave integrated circuit (MMIC) products, including four wideband low noise amplifiers (MMA040AA , MMA041AA, MMA043AA and MMA044AA) and two wideband MMIC switches (MMS006AA and MMS008AA). 

Microsemi's new devices are suitable for applications primarily within the defence and industrial markets, including receiver front end amplifiers for electronic warfare (EW) and signal intelligence (SIGINT); and wideband bench top and portable measurement equipment up to 26 GHz. 

 "Our new high linearity MMIC amplifiers and switches represent Microsemi's significant investment in expanding our Forever MMIC product portfolio as we continue addressing customers' highly specific and complex MMIC requirements with affordable, low-risk solutions that can also reduce end-equipment bill of materials costs and represent long-term value to the customer," said Kevin Harrington, director of strategic marketing for Microsemi's RF/Microwave Discrete Products business unit. "The Forever MMICs are another example of Microsemi's steadfast commitment to providing a continuous supply of product for the support of long-term defense, industrial and commercial programs."

Compared with existing market solutions, Microsemi's new wideband low noise MMIC amplifiers are said to deliver excellent performance with flat gain over a wide frequency range, and significantly better output third-order intercept point (OIP3) performance. 

Similarly, the new GaAs MMIC switches provide broad frequency coverage combined with superior insertion loss, isolation and input third-order intercept point (IIP3) performance. Global market research and consulting company Strategy Analytics estimates that GaAs MMICs sold into the EW, radar and microwave communications markets will reach $500 million by 2019.

The MMA040AA, a DC to 28 GHz distributed low noise amplifier, features a low noise figure of 2.5 decibel (dB), flat gain of 16 dB and provides 27 decibel-milliwatts (dBm) of OIP3 linearity. The MMA041AA, a DC to 26 GHz distributed low noise amplifier, features 3.2 dB noise figure, 18 dB gain and 35 dBm of OIP3 linearity. The MMA043AA, a 0.5 to 12 GHz low noise amplifier, offers a 1.4 dB noise figure, 16.5 dB of gain and 29 dBm of OIP3 linearity. The MMA044AA low noise amplifier operates across the 6 to 18 GHz band and provides a low noise figure of 1.7 dB, in combination with 21 dB of gain and 30 dBm of OIP3 linearity.

The MMS006AA, a DC to 20 GHz single pole double throw (SPDT), non-reflective MMIC switch, features high isolation of 45 dB and low insertion loss of 1.5 dB at 15 GHz. The MMS008AA is a DC to 8 GHz single pole four throw (SP4T), non-reflective MMIC switch that offers over 45 dB of isolation and less than 1.7 dB insertion loss. 

Both devices handle up to 30 dBm of input power and offer high input third-order intercept performance of 42 dBm and 46 dBm respectively. All six MMIC devices feature RF ports that are internally matched to 50 Ohms and are available in bare die, which facilitates easy integration into multi-chip modules (MCMs).



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.
