A Broad-Band 1:4 Static Frequency Divider MMIC in InPHBT

Abstract

This paper design and realize a broad-band 1:4 static frequency divider MMIC in 0.7$\mu$m InGaAs/InP DHBT technology. It is realized in a complete circuit structure and can be directly used in high precision instruments and relative systems to replace divide modules. Test results show that it can operate from 1GHz to 48GHz with sine-wave input. The input power dynamic range is from -10 to 10 dBm during the whole bandwidth. The output power is all above 0dBm and the SSB phase noise is -141.15dBc/Hz at 24GHz input.
