A 71–86GHz multi-tanh up-conversion mixer achieving +1dBm OP1dB in 0.13 μm SiGe technology

A Low-Power W-Band SiGe-HBT Double-Balanced Up-Conversion Mixer With an Integrated Second-Order IF Low-Pass Filter

“…The discrepancy between measurement and simulation at the midband is attributed to extra passive component losses in the LO and RF MNs. The LO-to-RF isolation is determined based on the I summarizes and compares the performance of prior published W -band SiGe-HBT active up-conversion mixers [8], [9], [10], [11], [12].…”

“…The CE is biased at J C = 2.3 mA/µm 2 for low current consumption. Moreover, degeneration resistors (10 ) are added for dc stability and to further improve linearity of the g m stage at the expense of conversion gain.…”

“…For instance, the number of required up-conversion mixers directly scales with the number of TX channels in a phased array, necessitating the minimization of mixer power consumption while ensuring sufficient conversion gain and linearity performance for higher-order modulation schemes. To date, there have only been a limited number of SiGe active up-conversion mixers [8], [9], [10], [11], [12] reported with marginal OP 1dB and considerably higher power consumption.…”

28-GHz CMOS Up-Conversion Mixer With Improved LO Second-Harmonic Leakage Signal Suppression for 5G Applications

“…Table I summarizes the measured results of the proposed up-conversion mixer with IF amplifier and LO buffer and compares its performance with those of other published mmWave up-conversion mixers [18]- [25]. To the best of our knowledge, previously published related papers reported neither the problem nor the performance of the 2LO leakage signal of the mmWave up-conversion mixer for a 28-GHzband 5G dual-conversion single-quadrature transmitter.…”

An E-band 40dB dynamic range multi-tanh power detector in 0.13μm SiGe technology

“…Another method to improve the dynamic range is the use of detectors in a ladder topology with attenuators, as explained in [4], which results in an increase in the complexity, size and power consumption of the overall detector. In this paper we show a novel PD topology intended for an E-band transceiver like the one demonstrated in [1,5]; replacing the bipolar differential amplifier that is used in [1] with a multitanh three transistor hybrid transconductance stage [6,7]. Applying this novel topology nearly doubles the logarithmic dynamic range, and allows the detection of signals ranging from -23.5dBm to 17dBm, without digital tuning or the use of cascaded detectors.…”
