STMicroelectronics unveils chip for Wi-Fi

STMicroelectronics, a semiconductor company has launched a new chip for WiFi. ST's new DIP2450 diplexer is used to connect a Wi-Fi IC to a single antenna and it simplifies circuitry and saving pc-board space. It can also connect a Bluetooth IC to the same antenna. The DIP2450-01D3 is in mass production now in the 1.1 x 1.25 mm 4-bump wafer-level chip-scale package (WLCSP), priced from $0.12 for orders over 1,000 pieces.

Leveraging ST's Integrated Passive Device (IPD) process technology, the DIP2450 has small dimensions of only 1.1 x 1.25 mm and passes signals efficiently enabling high-speed communications and low power consumption, said a press release.

The DIP2450 supports the high-speed dual-band Wi-Fi standard (IEEE 802.11n), permitting multi-channel communications in the 5GHz band, in addition to the established 2.4GHz operation. This allows extra user capacity as well as higher data rates per user.

ST's DIP2450 diplexer has been validated for use with ST-Ericsson's CW1260 dual-band Wi-Fi system-on-chip for multi-radio mobile applications. The CW1260 will also use two other ST IPD products, a 5GHz band pass filter and a matched balun (a signal-transforming device), added the release.
