Michaelsen, R S, Johansen, T K, Tamborg, K M, Zhurbenko, V & Yan, L 2017, ' An X-band Schottky diode mixer in SiGe technology with tunable Marchand balun ', International Journal of Microwave and Wireless Technologies, vol. 9, no. 5, pp. 965-976 . https://doi.org/10.1017/S1759078716001069
In this paper, we propose a double balanced mixer with a tunable Marchand balun. The circuit is designed in a SiGe BiCMOS process using Schottky diodes. The tunability of the Marchand balun is used to enhance critical parameters for double balanced m

In this paper, a passive double-balanced mixer in SiGe HBT technology is presented. Owing to lack of suitable passive mixing elements in the technology, the mixing elements are formed by diode-connected HBTs. The mixer uses lumped element Marchand ba

In this paper, we present flicker noise measurements of two X-band direct conversion mixers implemented in a SiGe:C BiCMOS technology. Both mixers use a ring structure with either Schottky diodes or diode-connected HBTs for double balanced operation.

Baluns are used to transform an unbalanced input signal into a balanced output signal. Baluns are essential components in many microwave circuits, e.g., balanced mixers, or other differential architectures. When the signal is received by the antenna,

In this letter, a novel modified Marchand balun configuration with tunable phase balance is analyzed and verified experimentally. It is proposed to add a shunt susceptance in between the two couplers of the Marchand balun. This allows for a change in

A new type of Marchand balun is presented in this paper, which has the property of complex impedance transformation. To allow the Marchand balun to transform between arbitrary complex impedances, three reactances should be added to the circuit. A det
