MGA-81563-TR1G Chipset

MGA-81563（0.1-6 GHz 3V, 14 dBm Amplifer）

Introduction

The MGA-81563 is an economical, easy-to-use GaAs MMIC amplifer that offers excellent power and low noise figure for applications from 0.1 to 6 GHz. Packaged in an ultra-miniature SOT-363 package, it requires half the board space of a SOT-143 package.

The output of the amplifher is matched to 500 (better than 2.1:1 VSWR) across the entire bandwidth.The input is partially matched to 50N (better than 2.5:1 VSWR) below 4 GHz and fully matched to 500 (better than 2:1 VSWR) above. A simple series inductor can be added to the in-put to improve the input match below 4 GHz. The MGA-81563 allows a wide dynamic range by offering a 2.7 dB NF coupled with a +27 dBm Output IP.

The circuit uses state-of-the-art PHEMT technology with proven reliability. On-chip bias circuitry allows operation from a single +3 V power supply, while resistive feedback ensures stability (K> 1) over all frequencies and temperatures.
