Avago Technologies announced the availability of its MGA-635P8 low-noise amplifier (LNA) for base station RF front-end design. The device can be used in a variety of cellular applications, such as in the first stage of cellular base station transceiver radio cards, tower mounted amplifiers (TMA), combiners, repeaters and remote/digital radio heads.
The new MGA-635P8 LNA adds to Avago’s LNA family series, which includes the previously released MGA-633P8 (450 MHz up to 1,5 GHz) and MGA-634P8 (1,5 GHz up to 2,3 GHz). With the addition of the new 2300 to 4000 MHz model, Avago provides a family of production ready LNAs for high-volume GSM, TDS-CDMA and CDMA cellular infrastructure applications.
The MGA-635P8 boasts a noise figure of 0,56 dB, 0,75 dB maximum, at 2500 MHz. At 2500 MHz and operating from 5 V with a 56 mA bias current, it delivers OIP3 performance of 35,9 dBm. With built-in active bias circuitry, operating current is adjustable, allowing designers to make tradeoffs between operating current and output linearity while maintaining an optimum noise figure.
