@conference{10902/3297, year = {2007}, month = {9}, url = {http://hdl.handle.net/10902/3297}, abstract = {An ultra-low cost and high performance RF scalar network analyzer for research and educational purposes have been developed. This device is based on a low cost Schottky “zero-bias” sensor diode connected to a microstrip directional coupler to measure the reflection port and a basic spectrum analyzer with tracking generator to measure the transmission port. A high impedance video output has been added to the detector circuitry in order to make compatible this device with the usual circuitry available in a basic RF laboratory (multimeter and an educational spectrum analyzer). The able to measure the magnitude of S11 and S21 scattering parameters coupled with the ultra-low cost of the circuitry, makes this system interesting tool to use by users at any level.}, publisher = {URSI 2007, XXII Simposium Nacional de la Unión Científica Internacional de Radio, La Laguna}, title = {Circuito conversor de analizadores de espectro de bajo coste en analizadores de redes escalares}, author = {Zamanillo Sainz de la Maza, José María and Álvarez Barba, Jorge and Pérez Vega, Constantino and Mediavilla Sánchez, Ángel}, }
