Abstract
A distributed amplifier topology with distributed feedback includes a plurality of amplifier stages, each of which includes a FET, MESFET or HEMT. A negative feedback network is provided with each amplifier stage which enables the gain of the distributed amplifier to be reduced by varying the negative feedback. An important aspect of the invention relates to the fact that the gain can be varied with virtually no affect on the bandwidth performance of the product and without significantly affecting the return loss, IP3 and noise figure performance of the device.
