LNAs Feature Bypass and Shutdown Functionality

low noise amplifiersAvago Technologies announced four low-noise amplifiers (LNAs) to extend the RF performance and diversity of LNA portfolio. The modules feature high linearity that improves an application’s ability to distinguish between desired signals and spurious signals received close together. The MGA-6x606 LNAs target WiFi and WiMAX data cards, handsets and other portable devices, while the two-stage MGA-13x16 LNAs target GSM, CDMA and W-CDMA cellular infrastructure applications such as base station radio cards. The Monolithic Microwave Integrated Circuit (MMIC) LNAs use the company’s 0.25 um GaAs Enhancement-mode pHEMT process to achieve leading low noise figures and high linearity. The 1.5-3.0 GHz MGA-64606 LNA and 2.5-4.0 GHz 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. For cellular infrastructure manufacturers, the 0.4-1.5 GHz MGA-13116 LNA and 1.5-2.5 GHz 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.
