HMC799LP3E v01.1009 DC - 700 MHz, 10 kOhm TRANSIMPEDANCE AMPLIFIER Typical Applications Features The HMC799LP3E is ideal for: 10 kOhm Transimpedance • Laser Sensor Very Low Noise: 150nA Input RMS Noise over 700 MHz Bandwidth • FDDI Receiver 700 MHz Analog Bandwidth • CATV FM Analog Receiver Wide Dynamic Range: +65 dB • Wideband Gain Block Low Power: 70mA from Single +5V Supply • Low Noise RF Applications 16 Lead 3x3 mm SMT Package: 9mm² 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- 11 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 T 50 ohms. External matching is not necessary. The M HMC799LP3E exhibits excellent gain and output S power stability over temperature, while requiring a - minimal number of external bias components.
