Description The 100G-HS-PD is a high speed photodiode designed for W band operation. It comes in a fibre pigtailed module with a 1mm ‘W’ connector electrical interface. There is no internal load resistor in the module, which enables the output mm-wave power to be maximised. The module is suitable for use with an external bias T. The edge coupled PiN photodiode design gives a good trade-off between high frequency operation and high responsivity, providing a useful device for laboratory applications. The chip capacitance is ~ 30 fF at –2V giving a predicted 1/(2πRC) bandwidth > 100 GHz in the absence of package parasitics and carrier life-time effects.
