- 論文の詳細を見る
A 15-50GHz-band GaAs MMIC variable attenuator has been developed for microwave and millimeter-wave wireless communications systems. The attenuator employs a balanced distributed configuration using shunt connected HEMT's in order to realize a broadband operation, a low insertion loss and a good impedance matching with simple control bias scheme. The MMIC was fabricated with a pseudomorphic HEMT device technology. It has exhibited an insertion loss as low as 1.6dB with an attenuation control range as wide as 21dB at 26GHz. It has also shown a good linearity of an input power of more than 12dBm at 1-dB compression point and that of 26.3dBm at a 3rd-order intercept point.
