  • Abstract
    An even harmonic type direct conversion receiver (EH-DCR) has an advantage of suppressing a degradation of sensitivity caused by interferences such as second order intermodulation and self detected local oscillator noise, so dynamic range of the receiver is as same as that of heterodyne receiver. This paper presents a design condition of the even harmonic quadrature mixer in the EH-DCR. A developed 1.9GHz-band EH-DCR has a sensitivity of ¿10ldBm and an intermodulation characteristic of 49dB. These results satisfy the requirements of Personal Handyphone System in Japan.
