Efficient Design and Analysis of Airborne Radomes
A fundamental function of the radio portion of all wireless systems involves signal amplification. Naturally there are many different amplifi cation requirements as one navigates the modern transceiver but as a result of new system demands and the requirement to utilize critical building blocks within their optimum range, the need for signal level stability has become more and more critical. This heightened importance has focused attention on the variable gain amplifi er (VGA) and the use of its primary function, to maintain a constant output over a specific range of input signal intensity.
As a key contributor to component and system evolution, Hittite Microwave Inc. is proud to announce the introduction of new digital and analog VGA’s to its product family that address this system requirement. This new VGA family exhibits the desired gain control accuracy while improving traditional product performance and increasing bandwidth capability, as well as conserving board space and reducing overall component cost.
