Avago LNAs target Wi-Fi and WIMAX data cards

The two-stage MGA-13x16 LNAs target GSM, CDMA and W-CDMA cellular infrastructure applications such as base-station radio cards.

The LNAs feature high linearity that improves an application's ability to distinguish between desired signals and spurious signals received close together.

The Avago Monolithic Microwave Integrated Circuit (MMIC) LNAs leverage the company's proprietary 0.25um GAAS Enhancement-mode pHEMT process to achieve low noise figures and high linearity.

The 1.5-3GHz MGA-64606 LNA and 2.5-4GHz MGA-65606 LNA have switchable shutdown and bypass functionality that enables them to be bypassed during periods of high input signal power.

This feature reduces current consumption, conserving battery life in portable devices.

The MGA-64606 addresses GPS, WIMAX, WLAN, Wibro and DMB, while the MGA-65606 addresses WIMAX and Wireless Local Loop.

The 0.4-1.5GHz MGA-13116 LNA and 1.5-2.5GHz MGA-13216 LNA enable usage of a single LNA, instead of the two components normally required, while still delivering low noise with good input return loss, high linearity and high gain.

Designers can achieve optimum performance with minimum matching at the input, output and the inter stage between the two LNAs.
