This thesis presents a noise-canceling LNA based on a complementary common-gate commonsource combination. It provides active balun functionality with a single-ended input that is power matched to the antenna and a differential current output driving a passive mixer. By allowing class AB operation for both outputs, the LNA achieves a high compression point and its outputs remain balanced under i...

A coplanar millimeter wave doubler MMIC covering the entire G-band was developed. Based on a 50 nm metamorphic HEMT technology, the circuit demonstrates an output power of more than –12 dBm between 150and 220 GHz for an input power of 0 dBm. By increasing the input power to 12 dBm an output power exceeding 0 dBm was obtained in the frequency range between 180and 220 GHz. Good fundamental reject...

In this paper, a 77 GHz microstrip dipole antenna is integrated on a layered 11.4 μm SiO2 and a silicon substrate with thickness of 670 μm. The unbalanced microstrip line is balanced by using a lumped LC circuit balun to feed both of the dipole arms. To decrease the substrate loss and hence increase the antenna gain, Localized Backside Etch (LBE) module offered by IHP is utilized to etch the ar...

A novel compact wideband differential bandpass filter with wideband common mode suppression using a Marchand balun is presented in this paper. Open/shorted coupled lines and stubs are used to improve the selectivity for the differential mode and common mode suppression. The demonstrated filter with a compact size of 50mm × 30mm exhibits a fractional bandwidth of 53% centered at 3.0GHz and 13 dB...
