IPAD- integrated passive devices applications
New, high-performance, thin-film IPAD technology
STMicroelectronics introduced IPAD thick-copper process delivering high-performance, low-cost space-efficient devices such couplers, baluns, diplexers filters. With copper insulated glass substrate, offers best-in-class performance wireless communication devices integrated modules. Applications benefitting from technology include multimode/multiband cellular phones broadband wireless access such WiMax, WLAN Bluetooth.
Main functions
Wideband coupler
Wideband high-directivity couplers designed measure forward reverse power antenna GSM/3G applications. These devices customized wideband operating frequencies with less than insertion losses transmission bands (824 1980 MHz) housed flip-chip packages.
Power-amplifier harmonic filter
Low-pass filters developed filter harmonics generated power amplifiers GSM/3G applications. ST's devices customized low-band (EGSM CEL) high-band frequencies (PCS DCS). These devices delivered bare mounted film frame (ready pick place assembly module).
Balun with integrated matched network
baluns designed easily implemented designs with need external discrete components. level integration offered IPAD technology provides high-quality matching network optimize power transmission efficiency. Housed small package, they offer over space saving versus usual LTCC solutions. baluns optimized terms insertion losses, amplitude phase imbalance connectivity multiband phone applications.
benefits
High performance substrate High accuracy simulation models board space saving Reduces component count system cost Custom standard product approach Standalone wafer mode delivery
Main applications
Low-loss diplexer
ST's low-loss frequency diplexers split signals from common port (antenna) other ports paths). targets multiband cell phones sharing same antenna CEL, EGSM, DCS, PCS, WCDMA Band operation. optimized reduce insertion losses each path higher transmit power efficiency improved sensitivity.
Multiband/multimode phones power control Front-end modules transceiver modules Broadband connectivity: Bluetooth, WLAN, GPS, WiMax, UWB, Transferjet
