We report the packaging and first measurement of Indium Phosphide (InP) monolithic microwave integrated circuits (MMICs) low noise amplifiers (LNAs) operating at cryogenic temperatures.
This paper will propose one vision for an interstellar program. It will include a discussion of mission concepts as well as technological requirements for accomplishing those missions.

A number of monolithic W-band power amplifiers have been developed for local oscillators of the Far Infrared and Sub-millimeter Telescope.
The Heterodyne Instrument (HIFI) for the Far-Infrared and Sub-millimeter Telescope (FIRST) requires local oscillators well into the terahertz frequency range.

We present results of developments of low noise millimeter wave receivers for space applications utilizing InP HEMT monolithic microwave integrated circuts (MMICs).
Significant advances in the development of HEMT technology have resulted in high performance cryogenic low noise amplifiers whose noise temperatures are within an order of magnitude of the quantum noise limit. Key to the identification of optimum HEMT structures at cryogenic temperatures is the development of on-wafer noise and device parameter extraction techniques. Techniques and results are described.
