H4E1N1
4.4–5.5 GHz, 20 W Psat, 3 W Pavg, 32 dB Gain, GaN MMIC Power Amplifier for 5G NR
Engineered for demanding RF systems.
Built for integration.
Description
The H4E1N1 is a multi-stage GaN MMIC power amplifier designed for 5G NR macro base stations and small cells operating across the n79, n46, and Wi-Fi 6E bands (4.4–5.5 GHz). It integrates the Doherty combining network on-chip, eliminating external splitters, combiners, and matching networks. Input and output are matched to 50Ω — drops directly into a standard RF layout without additional tuning.
Characterisation data covers real 5G NR OFDM waveforms at up to 100 MHz instantaneous bandwidth with carrier aggregation across 2×100 MHz — not extrapolated from CW measurements. The device delivers 3 W average power with –32 dBc ACPR (uncorrected) and ~7% EVM at 8 dB output back-off, meeting 3GPP NR base station requirements without DPD for many use cases.
Housed in a 4×5 mm QFN package with 50Ω matched I/O and no external components required for RF matching.
