Highly Linear InGaAs Photodiode (HLPD^®) Lab Buddy to 22 GHz

The New Era of Lab Buddy

The HLPD^® Lab Buddy is a stand-alone remotely accessible instrument for O/E applications. It incorporates Discovery Semiconductor's state-of-the-art highly linear photodiode with high power handling capability. Its high phase linearity makes it particularly attractive for precise timing applications such as photonic clock, time and frequency transfer, and photonic ADC. The HLPD^® Lab Buddy has a programmable bias voltage source that allows for highly linear operation at high input power and a built-in temperature controller for increased reliability. The bias and temperature can be set either from the front panel or via a remote computer interface. The HLPD^® Lab Buddy monitors its bias, temperature, and average photocurrent in real-time.
