摘要： A broadband power amplifier module for high bit-rate SONET/SDH transmission channels, such as OC-192 and OC-768 applications. The power amplifier module, or also frequently referred to as modulator driver module, comprises amplifiers (410, 415) connected in series to amplify an input signal.(405) A bias tee circuit (440, 417) is incorporated into the power amplifier module by connecting a conical shape inductor (440) between the output stage of the amplifiers and the supply voltage (Vdd) and connecting a pair of blocking capacitors (407, 412, 417) also at the output stage of the amplifiers. The conical shape inductor is adapted to provide high impedance over the entire approaching or exceeding the bandwidth frequency. A power detection circuit (430) can also be incorporated into the power amplifier module at the output stage of the amplifiers.
