A 23-28 GHz pHEMT MMIC Low-Noise Amplifier for Satellite-Cellular Convergence Applications

Satellite-cellular convergence promises to enable higher millimetre-wave bandwidth (data rate); beamformed better signal alignment (higher system efficiency); multi-connectivity data rates); and new use cases (verticals). Harnessing these opportunities will depend on overcoming challenges spanning shorter distance/reduced coverage component complexity; construction of antenna array over-the-air testing; coexistence issues between multiple mobile communication connections; performance tests; cybersecurity. This paper presents a broadband Monolithic Microwave Integrated Circuit (MMIC) Low-Noise Amplifier (LNA) based 0.15 µm gate length Gallium Arsenide (GaAs) pseudomorphic high electron transistor (pHEMT) technology for satellite-cellular applications. The designed three-stage 23-28 GHz LNA demonstrates an industry-leading flat gain response 30 dB, noise figure 1.70 dB very low power dissipation 43 mW. differential sensitivity spans 0.01 µs 0.04 dBm/Hz over the upper lower ends channel bandwidths 5G New Release frequency range n258 band (24.25-27.58 GHz). Moreover, regenerative analysis holds grand promise real-time component-level reconfiguration These applications include dynamic spectrum access; wireless transponder-transceiver technologies support; active resource usage; distributed sensing multi-standards wideband spectrum; massive complex time-varying datasets/features.
