Wolfspeed RF GaN meets 5G demands on PA design
Wolfspeed GaN on SiC products can replace inefficient silicon parts in 5G cellular transmitter amplifiers, achieving higher linearization, greater power density and improved thermal conductivity.
Improving Pulse Fidelity in RF Power Amplifiers
A radar system designer’s most coveted objectives are achieving a long range, adequate resolution to distinguish objects in close proximity to each other, and the ability to not only determine target velocities but target types in order to help differentiate friendlies from adversaries.A combination of both approaches is essential, and engineers can design for peak power points of the load-pull simulation while also paying attention to other parts of the circuit for baseband signal fidelity.
