title = "A D-band Frequency Quadrupler with 8.5dB Conversion Gain in 250 nm InP DHBT",
abstract = "This work presents a new-designed D-band multiplier with high conversion gain designed in 250 nm indium phosphide (InP) double heterojunction bipolar transistor (DHBT) technology. The quadrupler consists of two frequency doublers and a 2-stage common-emitter amplifier, with the embedded harmonic rejection module to suppress the useless signals. As shown in the post-simulation results, the proposed frequency quadrupler achieves a high conversion gain of 8.5 dB at 140 GHz. At a total DC power consumption of 51.1 mW, the output power saturates at 6.4 dBm. The operation frequency occupies a relatively wide bandwidth of 3-dB gain ranging from 124 to 156 GHz (BW3dB = 32 GHz) and a 5-dB gain bandwidth from 116 to 158 GHz (BW5dB = 42 GHz). The design also achieves good harmonic rejection ratios and a power efficiency of 8.37%.",
