Macom Announces Three AlGaAs PIN Diode Switches

New devices are designed for high frequency applications from 24 to 110GHz

Macom is introducing three PIN-based AlGaAs switches designed to minimise signal losses at very high frequencies. 

Built using the company's patented AlGaAs technology, the devices are the MASW-011094, a 24 to 37GHz  Ka-Band high power terminated SPDT PIN diode switch; the MASW-011029, a 60 to 110GHz wideband SP3T PIN diode switch; and the MASW-011087, a 14 to 38GHz  Ka-Band SP4T PIN diode switch.

The low loss translates to less noise generated, while maintaining transmit and receive signal integrity. In addition, the lower power loss allows for less compensation needed further down the RF and microwave signal chain.

According to Macom, AlGaAs-based switches have a clear advantage due to their power handling and low loss characteristics. A discrete heterojunction AlGaAs PIN diode switch demonstrates a factor of two reduction in high frequency insertion loss compared to other switches in its class which equates to reliable system performance at higher frequency bands.

"These parts complement our existing series of broadband AlGaAs switches," said Jack Kennedy, senior VP and general manager, Aerospace & Defence Solutions, at Macom. "We've also designed bias network chips, the MABT-011000, MA4BN1840-1 and MA4BN1840-2 for the existing MA4AGSW broadband series, altogether providing a breadth of AlGaAs offerings for a wide array of broadband applications."



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.
