HMC799LP3E

v01.1009

Functional Diagram

The HMC799LP3E is ideal for:

• Laser Sensor

• FDDI Receiver

• CATV FM Analog Receiver

• Wideband Gain Block

• Low Noise RF Applications

10 kOhm Transimpedance

Very Low Noise: 150nA Input RMS Noise

over 700 MHz Bandwidth

700 MHz Analog Bandwidth

Wide Dynamic Range: +65 dB

Low Power: 70mA from Single +5V Supply

16 Lead 3x3 mm SMT Package: 9mm2

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.
