Can you perhaps provide more specifics as to frequency (MHz or GHz) range, required NF, required dynamic range required (e.g. IP3 point), and expected current range (power budget), or perhaps even the final application?
Not all applications required the absolute *best* noise figure that state-of-the-art technology has to offer, as sometimes the application's environment (preceded by perhaps PIN diode switches or a circulator) will 'override' or dominate the NF of the transistor used anyway.
