Thin‐film barium strontium titanate varactor tunable dual‐band quadrature hybrid coupler

Abstract: A thin‐film barium‐strontium‐titanate (BST) and a conventional silicon varactor tunable dual‐band quadrature hybrid couplers are characterized and compared in this article. Both structures are composed of four quarter‐wavelength sections at a frequency located between the two operating frequencies, and with two pairs of open‐ended stubs. Frequencies tuning make used of BST interdigital and silicon varactor diode capacitors connected at the open‐ended stubs. The characterized BST interdigital capacitor presents… Show more

“…From Table 2, it can be seen that the proposed reconfigurable coupler has been implemented using microstrip technology with commercially available diodes, which reduces the cost compared to the tuning elements, such as the RF MEMS [11], [13], [22], or tunable active inductors [21]. Furthermore, the proposed configuration allows for reconfigurable applications.…”

“…In this area, the complexity as well as the cost increase with a number of switching between the frequencies bands of the radio terminals [2]- [10]. Recently, the development of reconfigurable wireless components has received many attentions for benefit of small size, reduced cost, and good flexibility for different system standards [3], [11], [12]. For high-performance, the system would require them to be reconfigurable in terms of frequency, coupling ratio and phase.…”
