Miniature Bandpass Filter Targets 2.45 GHz Apps

Designed for use in IEEE 802.11b WLAN and Bluetooth applications, a new multilayer ceramic bandpass filter achieves maximum attenuation levels of 14 dB and 20 dB at 1.9 GHz and 5.0 GHz, respectively, with a maximum insertion loss of 2.0 dB. The LTF2012B-F2R4B filter, manufactured with a proprietary ceramic material and process, performs in 2.45 GHz platforms over a full temperature range of -55°C to +125°C. The filter has a 0805 footprint (2.0 mm x 1.2 mm) and a low profile of 1.0 mm. It is reflow solderable. For details, contact TOKO AMERICA INC., Mount Prospect, IL. (847) 297-0070.
