The GPS filters B69812N1577B302 and B69812N1577D302 from Epcos are targeted at navigation systems in cars, ships, handheld devices and mobile phones. In comparison with previous filters, the company says they are distinguished by a 35% smaller space requirement and a signal-to-noise ratio of up to 50 dB for the various mobile radio frequencies.
The UMTS duplexer (B69969N2047A760) has been developed for the latest 3G mobile handsets. This product takes up 25% less space than its predecessor from Epcos and has a reduced typical TX insertion loss of 1,1 dB. The antenna and I/O pads are located on opposite sides. This simplifies signal routing and thus board layout.
Like all ceramic filters, the UMTS duplexers and the new GPS filters feature very good power compatibility (30 dBm or better) and high dielectric strength. Based on LTCC, Epcos' multilayer ceramic filters feature a completely new filter technology. Filter types B6989M2447C183 (bal. 50:50 Ω), B69893M2457B101 (bal. 50:100 Ω) and B69893K2457A101 (unbal. 50:50 Ω have been developed for IEEE standard 802.11 b/g and for Bluetooth applications. Type B69883M5427B110 (bal. 50:100 Ω) is suitable for applications to IEEE 802.11 a.
Components based on LTCC can be made smaller than conventional ceramic filters and offer high economies of scale. The company's smallest filters currently have a footprint of 2 x 1,5 mm. The balanced terminals can replace the discrete baluns generally used, giving space and cost savings combined with typical ceramic benefits such as low temperature drift and high power compatibility.
