What made you select the Guerrilla RF GRF0135 GaN HEMT Power Transistor?
I chose the Guerrilla RF GRF0135 GaN HEMT Power Transistor because it gives RF power amplifier designers an unusually broad combination of output power, bandwidth, and efficiency in a compact surface mount footprint. Covering DC to 3.2 GHz with 150W P3dB capability, the device is perfect for wideband architectures where engineers need to support multiple frequency bands or waveform types without redesigning the output stage. Applications such as cellular infrastructure, radar, communications systems, and RF test instrumentation all place unique demands on power transistors, including high peak-to-average ratios, thermal management challenges, pulse fidelity, and maintaining linearity across wide operating bandwidths. Designers working in these environments often need to balance output power with efficiency while minimizing board space and simplifying matching network complexity, especially in next-generation systems that must support both linear and pulsed operation.
The GRF0135 addresses these challenges with a GaN-on-SiC process optimized for high power density and thermal performance. Operating from either 28 V or 50 V supply rails, the transistor delivers 51.8 dBm saturated output power with 13.8 dB saturated gain and 57% saturated drain efficiency at the 50 V, 150 mA, 3.2 GHz reference condition. Its unmatched architecture gives experienced RF designers additional flexibility to optimize impedance matching networks for bandwidth, efficiency, or linearity targets specific to the end application. The device is also 100% DC and RF production tested, which helps reduce performance variability in high reliability designs. Packaging the transistor in a compact 6 x 3 mm DFN-14 form factor further supports dense RF layouts where thermal and space constraints are critical considerations.
