Comparative Analysis of Fast Wavelet Transform for Image Compression for optimal Image Quality and Higher Compression Ratio

摘要

Oscillator represents the basic microwave energy source for all microwave systems such as radar, communication and navigation. A typical oscillator essentially consist of an active device and passive frequency determining resonant element such as dielectric resonator, micro strip resonator and tuned circuit for fixed frequency oscillators, varactor for tunable oscillators. The transistor used was fujitsu, FHX13LG, operating at DC bias of 2V and 25mA.The oscillator was designed using the 1/3 oscillation rule because of its effectiveness and simplicity. Oscillator feedback was connected to HEMT in a common source configuration using transmission line and capacitor. The emphasis has been on high power, low noise, small cost, high reliability and high temperature stability. Practical design aspects including the choice of transistor, negative feedback circuits, load coupling, low phase noise, quality factor and operation at the highest phase slope for minimum phase noise are included. This paper deals Design and Development of X band Oscillator for Telemetry Transmitter by using ADS simulation software and it has been designed at 8 GHz frequency.
