摘要

介绍了一种带片上线性L-C合成器的60ghz双平衡跨导混频器，用于射频和本LO信号的求和和阻抗变换。采用ab类偏置实现低静态直流功耗(1.2V时360µW)。在fLO=58GHz和PLO=0dBm时，gm混频器原型实现了6.9dB (50Ω) NFDSB、6.2dB功率转换增益、- 4.7dBm输入参考P - 1dB和+4.2dBm IIP3。

A 7dB NF 60GHz-band millimeter-wave transconductance mixer

A 60GHz-band doubly-balanced transconductance (Gm) mixer with an on-chip linear L-C combiner for RF and LO signal summation and impedance transformation is described. Class-AB biasing is employed for low quiescent DC power consumption (360µW at 1.2V). At fLO=58GHz and PLO=0dBm, the Gm-mixer prototype realizes 6.9dB (50Ω) NFDSB, 6.2dB power conversion gain, −4.7dBm input-referred P−1dB, and +4.2dBm IIP3.
