1-bit band-pass delta-sigma modulator (BP-DSM) can generate RF signal directly from 1-bit data stream in high dynamic range by oversampling technology without local oscillator (LO) and mixer, so the miniaturization of transmitter can be realized. Mea

This article presents a 4-way 2-D butler matrix (BM)-based beamforming network (BFN) using a multilayer substrate broadside coupled stripline (BCS). To achieve the characteristics of a compact, wide-bandwidth, high-gain phased array, a BCS coupler is

A 1-bit band-pass delta-sigma modulator (BP-DSM), which utilizes oversampling technology, allows a modulated signal to be directly output by using a high-speed 1-bit digital pulse train, thus realizing miniaturization of transmitters. For 1-bit BP-DS
