Low Noise High Linearity GPS LNA w/ Integrated Shutdown Function and Adjustable Operating Current- App Note

From Avago Technologies
 

 
Avago Technologies' MGA-635T6 is a low noise amplifier designed for GPS application. This amplifier is housed in a ultra thin small leadless package which have small footprint (2 x 1.3 mm2) and very low profile (0.4mm max.). By using Avago Technologies proprietary GaAs E-pHEMT (Enhancement-mode pHEMT) process, this LNA can achieve high gain operation with very low noise figures and high linearity. The uniqueness of using E-pHEMT technologies is the part still useable with low voltage supply. This is important where the critical functions of the mobile receiver still working at battery weak condition. This application note describes the design of a GPS LNA using MGA-635T6. The circuit is demonstrated on a low cost FR4 material with standard 0402 chip inductors. Following figures show some information on the view and stacking structure of the demoboard.

RF receivers are electronic devices that enable a particular radio signal to be separated from all others being received and converted into a format for video, voice, or data. Search by Specification | Learn more about RF Receivers
RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters. Search by Specification | Learn more about RF Filters and Microwave Filters
RF diplexers are three-port frequency-dependent devices that may be used as a separator or a combiner of signals. RF duplexers allow a transmitter operating on one frequency and a receiver operating on a different frequency to share a common antenna with a minimum of interaction and degradation of the different RF signals.

Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs. Search by Specification | Learn more about Oscillators
