Woburn, Mass.Skyworks Solutions Inc. has introduced bulk acoustic wave (BAW) filters for customer premise equipment (CPE) to allow co-existence between wireless local area networks (WLAN) in the home and enterprise, and WiMAX networks, which cover wider areas including neighborhoods and cities.
As both networks operate at very closely spaced frequency bands, these BAW filters reject the interfering frequencies while allowing the desired signals to pass for the selected network.
The SKY33107 is a WiFi reject/WiMAX pass, and the SKY33108 is a WiFi pass/WiMAX reject, BAW filter. Both 3 x 3 mm devices have very low in-band insertion loss and input and output return loss. They also exhibit optimum rejectionin the 2.4 gigahertz (GHz) WLAN band for the SKY33107, and 2.495 to 2.690 GHz WiMAX band for the SKY33108.
The SKY33107 is intended for use in 2.495-2.690 GHz WiMAX band transmitter applications, which also contain WLAN 802.11 b, g, n transmitters, while the SKY33108 is targeted at 2.400 to 2.473 GHz WiFi band transmitter applications which also encompass 2.495 to 2.690 GHz WiMAX transmitters. Both filters can operate over a -20 to 85°C temperature range and are available in a lead (Pb)-free, restriction of hazardous substances (RoHS)-compliant package.
Pricing: Approximately $1, but orders are based on quantity and technical requirements.
Availability: Engineering samples are available now, with full launch scheduled for the fourth quarter.
Datasheets: SKY33107 and SKY33108.
