Abstract
A transconductance stage has a common-emitter transconductance stage having common emitter transistors, a common-base transconductance stage having common base transistors, wherein collectors of the common emitter transistors and collectors of the common base transistors are cross-connected to allow in-phase signal combining, an input differential signal applied to the common-emitter transconductance stage and the common-base transconductance stage in parallel, and a selectable gain output, the output selectable between at least one high gain and one low gain, wherein the low gain is lower than the high gain. A switchable transconductance stage has at least one input voltage signal having a frequency in the microwave range, a switchable gain setting, the switchable gain setting having at least two gain settings, and an output current signal having a gain determined by the switchable gain setting.
