Abstract:	摘要： In this paper, a miniature switched beamformer module for 2.4-GHz applications is proposed. The proposed beamformer module is based on the integrated passive device technology, and it integrates a 4 × 4 Butler matrix, a single-pole four-throw beam-selection switch, and a p-i-n diode-based transmit/receive (T/R) switch into a compact module size of only 4.9 mm x 5 mm × 0.9 mm. To achieve the compact module size, bridged-T coils are used to replace the transmission line sections in the 4 × 4 Butler matrix and the T/R switch. The measured insertion loss at the center frequency of 2.4 GHz is within 10.89 ± 1.13 dB for the receive path and 11.33 ± 0.69 dB for the transmit path. The measured phase error is less than 8.4° at 2.4 GHz. The proposed beamformer features low cost, compact size, and low profile. It can help enable the use of phased array technique in handheld mobile devices. 其他題名： TMTT 出版者： New York: IEEE 出版日期： 2016-09 出處： IEEE transactions on microwave theory and techniques, 2016-09, Vol.64 (9), p.2933-2942 資源來源： IEEE Electronic Library (IEL) 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
