Published:2011/11/30 21:35:00 Author:May | Keyword: detector amplifier, without cooling | From:SeekIC

This circuit is a low-noise amplifier, its input isconnected with ORP10 lndium antimonide detector workingunder room temperature . Four low noise transistors are connected inparallelfor thefirst step in order to match with low noise level photoresistor (30Ω) connected in input end. Effective noise figure is 3dB, voltage gain is 220, bandwidth is above 1MHz.
