This paper presents a 60 GHz balanced low noise amplifier. Compared with single-ended structures, the balanced structure can obtain a better input/output return loss, a lower noise figure (NF), a 3 dB improvement of...
A broadband miniature doubly balanced diode mixer chip fabricated by Win's 0.15/zm pHEMT technology is presented. In order to save chip area, a four-fold modified Marchand balun is used. A coupled line U section impr...
A wide band (24–40 GHz) fully integrated balanced low noise amplifier (LNA) using Lange couplers was designed and fabricated with a 0.15 μm pseudomorphic HEMT (pHEMT) technology. A new method to design a low-l...
A 53 GHz Colpitts oscillator implemented in a SiGe:C BiCMOS technology is presented. Limited by a 26.5 GHz frequency analyzer, the oscillator was measured indirectly through an on-chip mixer. The mixer downconverted ...
A 4-12GHz wideband power amplifier,using a balanced configuration with a strip line Lange coupler, is designed and fabricated. This power amplifier shows a maximum continuous wave output power of 29.5dBm at 8GHz cente...
This paper presents a fully integrated 4 8GHz VCO with an invention——symmetrical noise filter technique.This VCO,with relatively low phase noise and large tuning range of 716MHz,is fabricated with the 0 25μm SMIC...
