A Broadband, Low Noise, Integrated 340 GHz Schottky Diode Receiver
Artikel i vetenskaplig tidskrift, 2012

A 340 GHz subharmonic Schottky diode mixer and a multioctave (3–16 GHz) custom low noise amplifier (LNA) have been integrated to form a compact receiver front-end module, exhibiting ultra low noise with an exceptional flat response and broadband instantaneous frequency coverage. At room temperature, a receiver noise temperature of 870 K is measured at an LO drive of 1.2 mW at 170 GHz. The total dc power consumption of the LNA is below 120 mW. Measurements are in good agreement with simulations taking the mixer and LNA mismatch interaction into account.
