The 39GHz 1W Power Amplifier is tailored specifically for mmWave 5G applications. It employs a 0.15um PHEMT process, providing high-performance operation within the frequency band of 38 to 42GHz. The device exhibits a gain of 19dB and an impressive third-order intercept point (IP3) of 40dBm. It achieves an output power level of 31dBm at a 1dB compression point (P-1dB), making it ideal for 5G network infrastructure that demands robust amplification and high linearity. Its design, housed in a surface-mount (SMT) package, ensures ease of integration into larger systems, while its design optimizations allow it to perform seamlessly across the targeted frequency bands.
