LNA module comes in ultra-thin package

San Jose, Calif.—Slated for cellphone handsets that use GPS (Global Positioning System) satellite reception, Avago Technologies 's ultra-thin LNA (low-noise amplifier) can improve receiver sensitivity to assure reliable satellite location.

Avago's MGA-635T6 LNA module is designed for handsets for location-based services, and for those that must meet the FCC (Federal Communications Commission) E911 (Wireless Enhanced 911) mandate for handsets.

Key Specs

According to Avago, its power-managed MGA-635T6 MMIC (monolithic microwave IC) touts the industry's lowest noise-figure of 0.86-dB (at 1.575-GHz). Other key RF specs include 14.6-dB of gain, 2.5-dBm output power (almost 2-mW at the 1-dB gain compression), and wide dynamic range. Typical input third-order intercept point is +3.5-dBm.

The MGA-635T6 can also operate at voltages as low as 1-V, and up to 3.3-V. Operating current is low as 4.5-mA at 1-V, with a total shutdown current of approximately 0.1-µA. The LNA also includes a CMOS-compatible shutdown pin to provide variable bias to the amplifier.

Ultra-Thin Packaging

Measuring 0.4-mm thick (0.016-in.), the device comes in a UTSLP (ultra-thin system level package) that permits it to be incorporated into hybrid module assemblies. These can include LTCC (low temperature co-fired ceramic) modules that often require components with a thickness of 0.6-mm or less.

On the inside, the LNA uses Avago's proprietary GaAs (gallium arsenide) E-pHEMT (enhancement-mode pseudomorphic high electron mobility transistor) process. The E-pHEMT technology is responsible for the device's high-gain with low noise-figure and high linearity.

Price And Availability

The MGA-635T6 LNA module is priced at about 46-cents each in 21,000-piece to 54,000-piece quantities. Samples and demo boards are immediately available, with production quantities anticipated by the end of the month.
