High-Speed Detector with Amplifier RD4020

Storage Temperature Range TSTG [Typical Values and Absolute Maximum Ratings]: typical:-45~+85; Rated: -55~+85 Operating Case-Temperature Range TC [Typical Values and Absolute Maximum Ratings]: typical:25; Rated: -40~+85 Bias Voltage VR [Typical Values and Absolute Maximum Ratings]: typical:5; Rated: 5~6

HSPD4040 is a high-speed detector module for digital/analog applications. An InGaAs PIN photodiode responds over1250–1650nm with matching electronics. Maximum bandwidth is40GHz, supply+5V, input standard single-mode9/125μm fiber, and RF output a2.92mm connector matched to50ohms. A sealed housing weighs under20g. The description states ROHS2.0 compliance with restrictions on hazardous substances in electrical/electronic equipment. After nearly two years of R&D,广州瑞东 developed two fully domestic high-speed PD products described as exceeding18GHz and40GHz bandwidth. The18GHz version has rise time<20ps and the40GHz PD<8.5ps. Responsivity is described as matching or exceeding comparable Finisar/Thorlabs imports,with well-controlled tail ringing. Without a TIA,the detectors provide very low noise for high-speed communications and femtosecond-laser testing at high cost effectiveness. The company's independently developed linear supply meets research needs for these detectors.

Wavelength Range: 900nm-1700nm 3dB Cutoff Bandwidth: 5GHz Saturation Optical Power: 5mW

This detector series is a direct replacement for Thorlabs battery-powered products and is described as matching or exceeding equivalent Thorlabs products in all performance aspects. In addition to standard specifications, customization can adjust parameters such as supply voltage and bandwidth to customer requirements. Designed specifically for laser measurement systems, the series has an internal battery and no gain amplification, offering a cost-effective detector for high-power laser laboratories.

Wavelength Range [Model PDA1000-2 in the Technical Table]: 900-1700nm dB Bandwidth [Model PDA1000-2 in the Technical Table]: 10kHz Conversion Gain [Technical Table Model PDA1000-2; High-Impedance Output Load; Gain Halved from Nominal with 50Ω Load]: 2.5×10⁴V/A

This detector series operates much like single-element detectors from Thorlabs and Newport and has identical power interfaces. It can directly replace equivalent products when Monitor output is unnecessary and bandwidth matches, with performance described as matching or exceeding comparable Thorlabs/Newport detectors. Beyond standard versions, customization adjusts supply voltage, gain, bandwidth and other parameters to customer requirements.
