PHOTODIODE
PIN photodiode amplifier
C4890
Wide bandwidth amplifier (1.5 GHz, 20 dB)
C4890 wide-band amplifier, when connected to a high-speed PIN photodiode (S5791, S5972, S5973, etc.) converts optical signals at a maximum
of 1.5 GHz into voltage outputs with exceptionally low distortion and 20 dB gain.
C4890 can also be combined with other types of PIN photodiodes and APDs (avalanche photodiodes) to serve as a high-frequency amplifier for
optical measurements in a wide range of fields including industry and research applications.
Features
l Wide bandwidth, high gain, flat gain spectrum
l Flat, low group delay characteristics and low noise
l Input/output impedance: 50 Ω
l Small size, light weight, low price
l Single power supply operation (+12 V)
Applications
l High frequency amplifier for measurement
l PIN photodiode evaluation
