CTS Electronic Components has introduced a surface-mount RF Bandpass Filter for use in vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) wireless communication systems such as cooperative Intelligent Transport Systems (C-ITS) including 802.11p for Wireless Access in Vehicular Environments (WAVE) and Dedicated Short-Range Communications (DRSC).
The CTS TCB001A Bandpass Filter can handle 2 Watts of average RF output power at the Antenna and is a necessary component to ensure compliance and non-interference to 3GPP for wireless infrastructure co-location/co-existence. This filter is composed of a ceramic block plated with silver (Ag), measures 4.0 x 3.0 x 2.0 mm and weighs 0.14 grams. The filter delivers 45 dB of rejection with insertion loss of less than 1 dB and return loss of at least 16 dB. It is rated to handle input power of up to 3 Watts (Avg) and 30 Watts peak power, at an operating temperatures from -50°C to +150°C.
Applications seeking either Power Class D of 28.8 dBm (0.8 W), or 2 W (33 dBm) at the Antenna require RF power levels which are supported by the TCB001A, but are not supportable by SAW/BAW/FBAR technology. In addition, the small size of this new CTS product is similar in size to typical packaging of SAW/BAW/FBAR. In addition to the TCB001A, CTS engineers are currently developing the TCB002A which supports ETSI EN 302 571 and/or 5 GHz WiFi co-location.
