1500 Gliz Tunable Source Using Cascaded Planar Frequency Doublers

A complete source for 1.5 THz has been built using a cascade of four planar doublers following a MIMIC based HEMT power amplifier. This driver is in turn driven by a times nine multiplier so that the complete source may be synthesizer controlled. The source is intended for use at 120 K and has been tested at 60-90 K. The peak output powers of the stages are first stage 53 mW, second stage 15 mW, third stage 2.0 mW and final stage 45 tt,W. The peak output was measured at 1484 GHz, although >1 iW is produced over the frequency range 1450-1620 GHz. Based on preliminary testing with lower power, it is expected that a power of 11..1W is sufficient to drive an HEB mixer.
