Wolfspeed talks 5G and launches new radar technologies at European Microwave Week

At European Microwave Week (EuMW 2018) in Madrid, Spain (25-27 September), Wolfspeed of Durham, NC, USA — a Cree Company that makes silicon carbide (SiC) power products and gallium nitride on silicon carbide (GaN-on-SiC) high-electron-mobility transistors (HEMTs) and monolithic microwave integrated circuits (MMICs) — is sharing its view on the upcoming 5G market while unveiling its expanded portfolio of radar and 4G/5G products.

Gerhard Wolf, VP & general manager of Wolfspeed’s RF division, is delivering an industrial keynote on technological challenges posed by the transition to 5G and how the industry can leverage GaN and LDMOS to achieve the greater bandwidth and efficiency that 5G requires. The firm is also featuring its new wideband, two-stage, LDMOS integrated power amplifier (PTNC210604MD) in a live demo at the event.

In addition to showcasing new communications parts, Wolfspeed is unveiling two new 28V GaN MMIC power amplifiers (PAs) for radar applications: the 25W CMPA5259025F and the 50W CMPA5259050F (commercially available now). The C-band MMIC power amplifiers are designed in a compact 0.5” square package with greater than 30dB small signal and nominally 50% drain efficiency. This combination enables phased-array radar designers to maximize the power per element for C-band radar systems, says the firm.

Both components are also used in linear and compressed amplifier circuits in marine radar, weather monitoring (Doppler weather radar), air traffic control (ATC), maritime vessel traffic control services (VTS), and port security applications. The 50W MMIC PA for C-band radar enables modular system design with increased reliability and lower maintenance costs, making it applicable to a variety of emerging radar applications. For example, the new amplifier is suitable for countries like India and USA as they upgrade radar capabilities at airports across their nations.
