Abstract
Intermodulation effects play a decisive role in any system relying on the linear transmission of signals, such as highspeed wireless communication. For the first time, this paper presents measured third-order and fifth-order intermodulation performance of a 300 GHz monolithic integrated circuit with anew photonic approach. Conventional amplifier characterization in this frequency range showed a small-signal gain of more than 15 dB, operating frequency range from 279 to 313 GHz, and a 1 dB compression point and saturated output power of1.6dBm and 6 dBm, respectively, from a one-tone power sweep. Using a novel photonic-based measurement setup, the amplifiers’ output-related IP3 and IP5 are measured to 13dBm and 11 dBm, respectively. The two-tone measurement uses the photonic mixing of three laser lines to generate the two-beat frequencies at 299and 301 GHz.
