This paper presents a module for Wi-Fi by using system-on-package (SoP) technology. This module is composed of a single-pole-double-throw (SPDT) IC, a power amplifier module (PAM), a Tx low-pass-filter (LPF), a matching stage for a PAM, a Rx band-pass-filter (BPF), and decoupling capacitors to reject DC bias noise. All components are fully embedded in organic substrate in order to implement a slim...
This paper presents the implementation of a front-end-module (FEM) for wireless Local Area Network (W-LAN) by embedding a power amplifier module (PAM) and a double-pole-double-throw (DPDT) switch IC in printed-circuit-board (PCB) by sequential build up process using polymers. Polymers are adopted as substrates and these substrates are composed of FR4 and Ajinomoto-bonding-film (ABF). Vacuum lamination...
This paper presents a compact RF front-end module (FEM) with the power amplifier module (PAM) for dual band Wireless LAN (W-LAN). The FEM is composed of a single-pole-double-throw (SPDT) IC, a PAM, two Tx LPFs, two matching circuits for 802.11 b/g (low band) and 802.11 a (high band), two Rx BPFs, Tx diplexer for low/high band, and Rx diplexer for low/high band. Tx diplexer, Rx diplexer, two LPFs,...
A compact RF front-end module (FEM) for Wireless LAN (WLAN) application was proposed by merging DC supply voltage lines. The proposed module had one DC supply voltage line and one external shunt capacitor. This paper approached the aspect of isolation among DC supply voltage signal lines instead of using RF chokes or external shunt capacitors. Three types of module were designed and fabricated to...
In this paper, a compact Wi-Fi/WiMAX RF quad-band front-end module (FEM) is designed and implemented in order to meet this multi-mode trend. A quad-band FEM consists of 2- and 5-GHz Wi-Fi bandpass filters (BPFs), a 3-GHz WiMAX BPF, and two diplexers based on LTCC technology. In addition, a 5-GHz film bulk acoustic wave resonator (FBAR) filter, a single pole double throw (SPDT), and a single pole 4...
In this paper, a compact quad-band module for Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) applications is realized by Low Temperature Co-fired Ceramic (LTCC) technology. The quad-band module is composed of four bandpass filters, and matching networks, which are fully embedded in the LTCC substrate, and two MMIC switches are attached on the substrate...
A compact RF front-end module for WLAN application is presented employing low temperature co-fired ceramic (LTCC) technology. It consists of a SiGe PA , a BPF for Rx, a LPF for Tx, and a matching circuit embedded in LTCC substrate. The total size of the module targeted is 4.5 mm x 3.2 mm x 1.4 mm. Measured results of the proposed module show an output power of 18 dBm and a gain of 27.8 dB in the Tx...
