RF front-end design of a planar broadband phased array for satellite reception

Design of a highly integrated Ku-band planar broadband phased array receiver with dual polarization

“…Ref. [3] and [4] are similar in intended function and therefore the main functional parameters are comparable (Table 1.) This work sets a new standard in number of channels per area (Density (ch/cm 2 )) and DC power consumption per channel (Pdc (mW/ch)).…”

“…Different system architectures have been studied in [2], where a system consisting of 24 antenna tiles with 8x8 antenna elements (AEs) is proposed. Achieving the required level of integration remains a big challenge with the previous limit being reached by [3] with LNA, phaseshift, summation, filtering, downconversion and antenna for an 8x8 array with one linear polarization on a single 98x98mm PCB and by [4] with LNA, phaseshift, frequency discrimination and antenna for 156 dual polarized AEs on a single 20cm diameter PCB. This paper presents another major step in functionality and integration with 128 Ku-band inputs on a 94x94mm footprint (i.e.…”

An ultra flat phased array Ku-band antenna with integrated receivers in SiGe BiCMOS

“…The significance of this work is in the level of integration of both antennas and RFICs. [9, 10] are similar in intended function and therefore the main functional parameters are comparable (Table 1). This work sets a new standard in number of channels per area (density (ch/cm 2 )) and DC power consumption per channel (Pdc (mW/ch)).…”

“…The NF as listed in this work is simulated over the full antenna scan angle to give realistic performance expectations. Unfortunately these numbers were not available in the references, but based on the monolithic microwave integrated circuit (MMIC) used in [9, 10] a minimum NF of 2 dB is found.…”
