The MGA-635T6 low-noise amplifier (LNA) module is designed for handsets operating with carriers that provide location-based services, as well as for meeting the FCC’s Wireless Enhanced 911 (E911) mandate for handsets. Although it is smaller and thinner, the device offers better performance than and is extremely cost-competitive with other GPS and ISM-band LNAs, according to the company. The amplifier features a noise figure of only 0.86 dB at 1.575 GHz.
The amplifier delivers 14.6 dB of gain, 2.5 dBm of output power (1-dB gain compression) and a wide dynamic range, with an input third-order intercept point of +3.5 dBm (all typical). The module runs on 1.0 to 3.3 V, with an operating current as low as 4.5 mA at 1 V, and a total shutdown current of approximately 0.1 microA. A 0.4-mm thick ultra-thin system level package (UTSLP) allows the LNA to be incorporated into hybrid module assemblies, including low-temperature co-fired ceramic (LTCC) modules. The device uses Avago’s proprietary GaAs enhancement-mode psuedomorphic high electron mobility transistor (E-pHEMT) process, Its CMOS-compatible shutdown pin can also provide variable bias to the amplifier.
Samples and demo boards are available now. Production quantities are scheduled to be available by the end of June.
