New Focus Model 1414 25-GHz IR Photodetector New Focus Model 14XX photodetectors were designed to offer the ideal combination of high-speed performance (up to 25 GHz) and optical-input flexibility. These high-speed photodetectors show flat response in both amplitude and phase up to 25 GHz and are optimized for frequency-domain applications.  An internal microwave housing suppresses noise, pick-up, and other artifacts. Moreover, to limit damage due to excessive voltage or mishandling, these photodiodes have damage-resistant bias circuits and are powered by an easily replaceable internal 9-V battery. All these detectors come equipped with a DC-bias monitor that has a transimpedance gain of 1 mV/µA and a 50-kHz bandwidth.  With optical-fiber input, the photodiode module can be connected directly to an electronic instrument, eliminating the need for an expensive high-frequency microwave cable.  The high-sensitivity 141X Series near-IR photodetectors use 25-µm-diameter back-illuminated InGaAs Schottky photodiodes with peak responsivities of 0.6 A/W at 1300 nm. The active layer is twice as thick as in the ultrahigh-speed 101X module, producing a 50% greater responsivity between 950 nm and 1650 nm. The conversion gain with a 50-W load is 15 V/W.
