The H4E1N1 from Millibeam is a Multi-Stage GaN Power Amplifier (PA) MMIC that operates from 4.4 to 5.5 GHz. It is designed for 5G-NR macro base stations and small cells operating in the n79, n46, and Wi-Fi 6E bands, fixed wireless access, and C-band infrastructure. This PA delivers a saturated output power of 20 W (~ 43 dBm) with a small signal gain of 32 dB and a power-added efficiency (PAE) of more than 40%. It integrates a Doherty combining network on-chip, thereby eliminating the need to use external splitters, combiners, and matching networks and simplifying the design.
The H4E1N1’s input and output ports are internally matched to 50 Ohms, providing a standard RF layout with no need for additional tuning. This power amplifier requires a 30 V DC supply. It is available in a 24-lead QFN package measuring 4 x 5 mm.
