Preamplifier

Price: 690,- EUR (Excluding VAT)   

Overview

THz detector amplifier is designed to amplify weak detector signals up to measurable level. Amplifier's input circuit is based on ultra-sensitive LT1055 op. amp. thus allowing to amplify a few hundreds of pA current signals from the detector's output.

Gain vs Frequency

Other features

Amplifier has a manually adjustable DC bias compensation. This allows to compensate DC current, produced by THz detector.

Recommended load impedance should be 1 kOhm or higher.

Availability

Amplifier is available in an aluminum case with 1.2 m length power supply cable and SMA connectors (SMA plug on input, SMA jack on output) or as a bulk PCB module. Available gain values: 10, 20, 30, 40 dB.
