CGHV37400F

400-W; 3300 – 3700-MHz; 50-Ohm Input/Output Matched; GaN HEMT for S-Band Radar Systems

Wolfspeed’s CGHV37400F is a gallium nitride (GaN) high electron mobility transistor (HEMT) designed specifically with high efficiency; high gain and wide bandwidth capabilities; which makes the CGHV37400F ideal for 3.3 – 3.7 GHz S-Band radar amplifier applications. The transistor is matched to 50-ohms on the input and 50-ohms on the output. The CGHV37400 is based on Wolfspeed’s high power density 50 V; 0.4 µm GaN on silicon carbide (SiC) foundry process. The transistor is supplied in a ceramic/metal flange package.

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.
