Functional Diagram
General Description
The HMC799LP3E is DC to 700 MHz Transimpe-
dance amplifier designed for opto-electronic laser
sensor applications, FDDI receivers and receiver
systems employing optical to electrical conversion.
This amplifier provides a single-ended output voltage
that is proportional to an applied current at its input
port. This current is typically provided by a photo-
diode. Operating from a single +5V supply,
HMC799LP3E features very low input referred noise,
and very large electrical input dynamic range exce-
eding 65 dB. 10 kOhm or 80 dB-Ohms transimpedance
gain provides very good sensitivity at higher data rates.
The output of HMC799LP3E is internally matched to
50 ohms. External matching is not necessary. The
HMC799LP3E exhibits excellent gain and output
power stability over temperature, while requiring a
minimal number of external bias components.
