HMC799LP3E v01.1009 DC - 700 MHz, 10 kOhm TRANSIMPEDANCE AMPLIFIER Typical Applications Features 10 kOhm Transimpedance The HMC799LP3E is ideal for: Very Low Noise: 150nA Input RMS Noise Laser Sensor 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: 9mm General Description Functional Diagram 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 11 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.
