A very small form factor and low profile quad-band System-in-Package (SiP) module based on the state-of-the-art 65nm CMOS IC is presented. The SiP module provides full function of 2.4G and 5G WLAN, Bluetooth, GPS, FM radio and FM transmitter. The highly integrated device incorporates single chip, RF front-end module, filters for WLAN and GPS, number of SMD components and EMI shielding. Very compact...
This paper presents a dual-band (2 and 3 GHz) and a single-band (2 GHz) highly-integrated WiMAX System-in-Package module based on LTCC (Low Temperature Cofired Ceramics). They comprise of complete passive and active RF frontend plus the RFIC for up- and down-conversion to the base band. Both modules support 1times2 (1 transmit, 2 receive paths) MIMO operability. The top level measurements of the SiPs...
In this paper a new approach for miniaturizing multilayer LTCC designs (Low Temperature Co-Fired Ceramics is proposed. Using the stacking options inside LTCC more consequently, a new very compact high-rejection balanced bandpass filter for WirelessLAN (based on IEEE 802.11a standard) is realized. The demonstrated filter performance is a very promising. With only 2.7 dB insertion loss in the band of...
This paper presents a highly integrated WiMax system-in-package (SiP) based on LTCC technology (low temperature co-fired ceramics). It comprises the complete passive and active RF frontend plus the transceiver RFIC for up- and down-conversion to base band. The overall size of such a smart package strongly depends on the applied technology and level of integration (multiband/multimode). The benefits...
This paper presents a high performance filter for wireless LAN applications in mobile phones. Excellent out-of- band attenuation performance in combination with low insertion loss is achieved by a combination of a SAW filter with high attenuation close to passband with a simple low-loss LTCC filter. The achieved performance makes it possible to use such filter in highly-integrated WLAN front-end modules.
This paper reports on the design of a balanced filter based on a new transformer type balun. The disadvantages and performance drawbacks of simple second order transformer are discussed and new third order balun structure is proposed. The new structure is realized as broadside coupled lines vertically stacked using multilayer low temperature co-fired ceramic (LTCC) technology. The resulting structure...
This paper presents a new very small low temperature co-fired ceramic (LTCC) diplexer based on a dual-band bandpass filter for wireless LAN (IEEE 802.11 a/b/g) application. The diplexer and the dual-band filter design have been realized and demonstrated in this article. Measurement results agree quite well with simulation. The new type of such diplexer significantly reduces the number of components...
