STMicroelectronics introduces the DIP2450 diplexer for connecting a WiFi IC to a single antenna. The device is suited for smartphones, tablets and other connected devices.

The diplexer measures 1.1mm x 1.25mm x 600�m and can also connect a Bluetooth IC to the same antenna. It leverages the company�s Integrated Passive Device (IPD) process technology to pass signals efficiently for high-speed communication and low power consumption. IPD integration also enables stable and repeatable�RF front-end characteristics

It supports the IEEE 802.11n WiFi standard, permitting multi-channel communications in the 5GHz band in addition to the established 2.4GHz operation. This enables extra user capacity and higher data rates per user, with handsets using IEEE 802.11n oprating at more than 60Mbps.

The diplexer has been validated for use with ST-Ericsson's CW1260 dual-band WiFi SoC for multi-radio mobile applications. It features typical insertion loss of 0.6dB (2.4GHz and 5GHz); and claims high attenuation and rejection of out-of-band frequencies.

The DIP2450-01D3 is in mass production in a 4-bump WLCSP, priced from $0.12 for orders over 1,000 pieces.
