This paper presents a front-end module (FEM) for Wireless Personal Area Network (WPAN). This module is composed of a switch IC for Tx/Rx, a Tx Balun, and Rx bandpass filter (BPF). These components are embedded in molding package by employing the proposed package technology. Molding package process is to add lamination and pattern in contrast to normal package of ICs. This process, therefore, has advantage...
This paper presents a compact GPS/BT/WiFi triple-band triple-mode RF front-end module (FEM) with Si-based embedded actives and LTCC-based embedded passives. The proposed RF FEM consists of a triplexer, baluns, matching circuits in the LTCC substrate, and a PA, an LNA, a SAW filter on the LTCC substrate. Furthermore, the proposed FEM has a silicon module on top of the LTCC substrate in which three...
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...
This paper presents a highly integrated low temperature co-fired ceramic (LTCC) RF front-end module (FEM) for cellular/GPS/PCS applications. First, a triplexer composed of two diplexers and a GPS SAW filter has been implemented. Measured results of the triplexer are summarized and compared with simulated results. Next, a cellular SAW duplexer has been integrated into the triplexer with a PI network...
