Design approach for I-Q Modulators using Millimeter-Wave Monolithic Doubly Balanced V-Band Star Mixers
نویسندگان
چکیده
In this paper, a doubly balanced V-band star mixer has been designed following the design method developed for I-Q modulators applications. The mixer has been designed using a commercial GaAs pseudomorphic HEMT process library. The mixer exhibits RF bandwidth over 45-65 GHz with local oscillator isolation better than 30 dB, and achieved a typical conversion loss of 9 dB. The IF modulation bandwidth is over 10 GHz, making the mixer suitable for high speed data transmission.
