Page 6: Operation
Operation Introduction The New Focus Models 1801 and 1811 125-MHz, low- noise photoreceivers address the needs of the photodetector community in the area of low-noise, high-gain, RF photoreception. These photoreceivers are available either DC or AC coupled. Their typical bandwidth is 125 MHz with a current gain of 40 V/... -

Model 0921 banana plug-to- microconnector cable and a Model 0922 microconnector-to-microconnector cable. If you have a New Focus Model 0901 power supply, use the Model 0922 cable on one of the supply’s 0.3-A microconnector outputs. Do not use the Model 0921 on the Model 0901 power supply’s 0.1-A... - Page 8 providing a minimum of 0.25 A of current on ±15 V. The convention of the three banana plugs is: Banana Plug Voltage +15 V Green COM/GND Black -15 V 2. Turn on the optical beam. 3. For free-space beam input, align the module so that the beam is incident on the detector surface.

Page 9: Theory
Theory The Model 1801 photoreceiver contains a silicon/PIN photodiode. The Model 1811 contains an InGaAs/PIN photodiode. In both models, the photodiode is fol- lowed by a low-noise transimpedance amplifier acting as a pre-amp with a compensating amplifier as the out- put stage. - Page 10 NEP Characteristics For Model 1801, the NEP from 0–10 MHz is 3.3 pW/ and from 10–200 MHz the NEP is 30 pW/ Therefore the integrated noise from 0–130 MHz is 328 nW and with a conversion gain of 2.4x10 V/W, the expected output noise voltage is 7.8 mV...
