Murata's SAW filter for Bluetooth and WiFi circuits simplifies designs
The latest advances in Murata's filter technology have led to development of a new SAW filter whose high power capability means it can be used as a top filter, replacing two interstage filters with a single component. In addition, the filter's external matching circuit requires just two inductors. This overall reduction in component count minimises a design's bill of materials and will be of particular benefit to OEMs making wireless consumer devices such as mobile phones.
The The filter can handle input signal levels of +27dBm for 500 hours at up to 85°C, or +24dBm for 5000 hours at up to 85°C. Voltage standing wave ratio (VSWR) is typically 1.4, with insertion loss typically 1.7 dB. Operating temperature is -30 to +85°C.
