This application note discusses the application of Avago Technologies` MGA-675T6 for 5-6 GHz application. The MGA-675T6 is integrated internally with shutdown and biasing circuitry. Besides reducing the complexity of the external circuitry, the shutdown circuitry allows the LNA to be easily shut down by an external voltage control. This feature ma

kes the MGA-675T6 suitable to be used in a mobile receiver where the amplifier can be switched off easily to reduce current consumption and to extend a battery life. By using Avago Technologies` proprietary 0. 5-micron GaAs E-pHEMT technology (Enhancement-mode pseudomorphic high electron mobility transistor), the MGA-675T6 can achieve excellent linearity, high gain and very low noise fi gure at low voltage and current. These are the key parameters to improve the sensitivity of the receiver. The low operating voltage and current is essential to modern portable devices such as notebook or mobile devices that are equipped with multiple wireless standards (WiMAX, WLAN, GPS, and Digital Television etc. ). Simultaneous applications of these functions always require high power consumption, especially digital TV which heavily involves image display. Thus, great power effi ciency to extend battery life becomes an important requirement for portable devices. While operating at 3 V and 10 mA, the MGA-675T6`s measured performance at 5. 5 GHz on the demonstration board is typically: 1. 75 dB NF, >17 dB gain, -3 dBm IIP3, and -9 dBm IP1dB. The device can be easily shut down through an external control voltage, and it will draw almost zero current ( A range). The MGA-675T6 is housed in an UTSLP (Ultra-thin Small Leadless Package) package with a very low profi le (0. 4 mm) and small footprint (2. 0 G— 1. 3 mm2) that requires only a small...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
