BeRex Adds New High Performance MESFET Chips

Low phase noise, high linearity MESFETs complement popular line of pHEMTs

BeRex has begun shipping a new family of GaAs MESFET chips, the BCF-series, which addresses the need for low phase noise with high gain and power in applications such as single and multi-stage amplifiers, oscillators, synthesizers, etc. ranging in frequency from DC to 26.5GHz. 

"These parts along with our existing pHEMT family of packaged and bare-die FET products go a long ways towards fulfilling the commitment to our clients of becoming their one-stop source for their RF and microwave FET needs", said Alex Yoo, VP of research and development at BeRex.

The BeRex BCF-series of MESFET chips are suited to both broadband and narrow band applications from DC to 26.5GHz.  Typical application requires a high level of OIP3 (Output Third-Order Intercept Point) linearity and a low phase noise that cannot be easily achieved with other technologies.

This BCF-series family consists of seven devices, each is built using a 0.25µm gate length and with a gate width of 200µm, 300µm, 400µm, 600 µm, 800µm, 1200µm or 2400µm, depending on the clients gain and power requirements (up to 1W for the largest 2400µm device).

The BeRex BCF-series chips are are now available in sample and production volumes.  

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.
