FCI-H125/250G-GaAs-100 GaAs Photodiode-Amplifier Hybrids

Frequency Bandwidth up to 0.25, 1 GHz; Low Cut-off Frequency DC-10 kHz; High Cut-off Frequency 100 kHz-1 GHz; Transimpedance 0.5-200 kV/A; Output Impedance 50 Ω; Output Voltage Swing ±1-±10 V Vigo System’s AIP, PIP, MIP, FIP and SIP configurable line series of infrared (IR) detection modules integrate the infrared photodetector and the preamplifier in a common package. This integration makes the detectors less vulnerable to over-bias, electrostatic discharge, electromagnetic interference (EMI) and other environmental exposures. Additional advantages of the integration are improved high-frequency (HF) performance, output signal standardization, miniaturization, and cost reduction. Vigo System’s broad line of transimpedance preamplifiers is especially designed for integration with each type of the supplier’s IR detectors. The configurable line of modules enables the selection of the active area, type of preamplifier and bandwidth of the detection module. This makes it possible to adapt the module to the needs of your own application. To obtain the most optimal parameters of integrated module each preamplifier is individually matched to the selected detector. The parameters of each integrated set will be known after final evaluation (matching, adjustment and final tests). If you need any assistance in selecting Vigo System products that are appropriate for your application, please contact the AMS Technologies IR detector specialists. Vigo System’s AIP series is a new generation of transimpedance, AC or DC coupled preamplifiers. It is designed to operate with either biased or non-biased Vigo System detectors. AIP is „all‑in-one” device – a preamplifier is integrated with a fan and a thermoelectric cooler controller in a compact housing. It is very convenient and user‑friendly device, thus can be easily used in a variety of applications. AIP series modules can be equipped with thermoelectrically cooled models of the PC, PCI, PV, PVI, PVM and PVMI IR detector series. Vigo System’s PIP series comprises programmable, “smart” preamplifiers, offering extreme flexibility combined with superior signal parameters and high reliability. A built-in voltage monitor allows to check and optimize the working conditions (supply voltages, detector bias voltage, first and last stage output voltage offset etc.). It is also possible to change the gain, coupling (AC/DC), optimize the first stage transimpedance and manually or automatically suppress the voltage offset. Optimized parameters are stored into the internal EEPROM memory and automatically loaded after the power is on. Reset to default settings is available at any time. For proper operation, the PTCC-01 TEC controller is required. PIP series modules can be equipped with thermoelectrically cooled models of the PC, PCI, PV, PVI, PVM and PVMI IR detector series. Vigo System’s MIP series provides medium-size transimpedance, DC or AC coupled preamplifiers, intended to operate with either biased or non-biased Vigo System IR detectors. MIP series modules are equipped with a fan, do not require any additional external heatsink and are one of the most user-friendly preamplifier series which surely facilitates work. MIP series modules can be equipped with thermoelectrically cooled models of the PC, PCI, PV, PVI, PVM and PVMI IR detector series. Vigo System’s FIP series of high-speed transimpedance, AC-coupled preamplifiers is intended to operate with the biased, TE-cooled IR detector models of Vigo System’s PV and PVI series. Thi series’ fast preamplifier enables precise I-V conversion, detector biasing up to 800 mV and simultaneously maintains compact size and keeps current noise low. FIP series modules are equipped with a fan and do not require additional heat dissipation. They are suitable for applications requiring wide frequency bandwidth. An additional DC output is available as an option. Vigo System’s SIP series of ultra-small transimpedance, AC- or DC-coupled preamplifiers is designed to operate with either biased or non-biased detectors. It is compatible with uncooled IR detectors (in TO39 package, SIP-TO39) or thermoelectrically cooled IR detectors (in TO8 package, SIP-TO8) of the PC, PCI, PV, PVI, PVM and PVMI series. SIP series modules are dedicated for OEM applications, require external heatsinks and provide a possibility to adjust gain (devices with a frequency bandwidth up to 100 MHz).

Infrared radiation generates charge carriers in the semiconductor active region decreasing its resistance. The resistance change is sensed as a current change by applying a constant voltage bias. The PC/PCI series devices are characterized by near linear current-voltage characteristics. The electric field in photoconductors is constant across the device. These components are based on sophisticated HgCdTe heterostructures for the best performance and stability and optimized for the maximum performance at λopt. Vigo System’s PC series features 1 µm to 12 μm HgCdTe uncooled, ambient temperature IR photoconductive detectors. The devices should operate in optimum bias voltage and current readout mode. Performance at low frequencies is reduced due to 1/f noise. The 1/f noise corner frequency increases with the cut-off wavelength. PC series devices are also available thermoelectrically cooled by two-stage (PC-2TE series), three-stage (PC-3TE series) or even four-stage (PC-4TE series) TEC structures, resulting in 1 µm to 14 μm (PC-2TE), 1 µm to 15 μm (PC-3TE) or 1 µm to 16 µm (PC-3TE) HgCdTe photoconductive detectors. These series are protected by a 3° wedged sapphire (wAl2O3, PC-2TE) or zinc selenide anti-reflection coated (wZnSeAR) window, preventing unwanted interference effects. The PCI series is optically immersed in order to further improve the parameters of the devices. This series’ cut-on wavelength is limited by GaAs transmittance (~0.9 μm). Corresponding to the PC series, PCI series components are also available either as 1 µm to 12 μm HgCdTe uncooled, ambient temperature IR photoconductive detectors or as 1 µm to 15 µm (PCI-4TE: 16 µm) HgCdTe photoconductive detectors that are thermoelectrically cooled by two-stage (PCI-2TE series), three-stage (PCI-3TE series) or even four-stage (PCI-4TE series) TEC structures, again with a 3° wedged sapphire (wAl2O3, PC-2TE) or wedged zinc selenide anti-reflection coated (wZnSeAR) window, preventing unwanted interference effects. For its range of PC/PCI HgCdTe (MCT) photoconductive detectors, Vigo System provides a broad range of selected line or configurable line infrared (IR) detection modules that integrate the IR photodetector with the preamplifier and – depending on the module series – also signal processing electronics, optics, heat dissipation systems and other components in a common package.
