Anadigics Inc. has released a family of three front-end ICs (FEICs) in low-profile standard packages targeting next-generation Wi-Fi smart phones and consumer electronics products.

According to Anadigics, the AWL9230, 9231 and 9232 ICs offer designers superior output power and efficiency for increased data rates and range, while preserving battery life in mobile devices.

The FEICs are claimed to offer the industry's highest level of GaAs on-chip integration by incorporating a power amplifier, an LNA, a Bluetooth path and an RF antenna switch, all in a single low-profile package measuring 3mm x 3mm x 0.55mm. The small physical size is made possible by the exclusive Anadigics InGaP-Plus process technology, which allows all three functions to fit on a single GaAs die.

The AWL9230 FEIC family is compatible with 802.11b/g and 802.11n MIMO Wi-Fi standards. With design space at a premium, the ICs are suitable for mobile products such as smart phones, cameras, game controllers, ultramobile notebooks and USB adapters.

The FEICs require only one capacitor and one inductor outside the standard plastic package and they are designed to interface directly with a Wi-Fi/Bluetooth chipset. The AWL9230 FEIC achieves 3.5 percent EVM and draws 140mA of current at an output power of 19dBm. Designed for lower-voltage applications, the AWL9231 achieves 3.5 percent EVM and draws 135mA of current at an output power of 18dBm.

For higher-power applications, the AWL9232 achieves 3.5 percent EVM and draws 175mA of current at an output power of 21dBm. All three have very low EVM floors at low output powers making them a perfect fit for 802.11n MIMO applications. All output powers noted are measured at the antenna port.

The single-die, standard plastic-package construction makes these devices robust and suitable for low-cost, high-volume manufacturing. The devices are RoHS-compliant.

Sample qualities are now available.
