ABSTRACT:
A wideband combiner includes a core amplifier for receiving first and second pairs of differential input signals and providing a single pair of differential output signals. The pair of differential output signals are a combination of the first and second pair of differential input signals and a signal gain is implemented between the received first and second pairs of differential input signals and the single pair of differential output signals. The core amplifier is configured to provide a gain value between the first and second pairs of differential input signals and the single pair of differential output signals. The signal gain is substantially constant across the frequency bandwidth of the core amplifier. A bandwidth peaking network is coupled to the core amplifier and includes (a) a first coil and a first resistor connected in series and (b) a second coil and a second resistor connected in series.
