Broadcom Inc. RF Amplifiers MGA-635T6-TR2G

The MGA-635T6-TR2G is a low noise amplifier (LNA) designed for GPS, ISM, and WiMax applications within the frequency range of 0.9 to 2.4 GHz. Utilizing Avago Technologies' proprietary GaAs Enhancement-mode pHEMT process, it achieves a low noise figure of 0.74 dB and a high gain of 14.5 dB at 1.575 GHz with a supply voltage of 2.85V. The device operates efficiently at supply voltages ranging from 1V to 3.6V, making it suitable for low power applications. The amplifier features a CMOS compatible shutdown pin, allowing for a shutdown current of less than 0.1 µA, and adjustable bias current through an external resistor. It has a compact surface mount package measuring 2.0 x 1.3 x 0.4 mm, which is beneficial for space-constrained designs. The MGA-635T6-TR2G is characterized by high linearity, with an input 1 dB compressed power of 2.5 dBm and an input 3rd order intercept point of 3.5 dBm, ensuring reliable performance in demanding environments. This product is suitable for engineers looking for a high-performance LNA for GPS and similar applications, particularly where low power consumption and compact size are critical.
