New DC to 700 MHz, 10 kOhm TIA for Laser Sensor Applications. 65 dB Dynamic Range & 150 nA Input RMS Noise over 700 MHz Bandwidth.
Chelmsford, MA, 12/02/2009 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced a new SMT packaged Transimpedance Amplifier (TIA), which is designed to meet the requirements of opto-electronic laser sensors, FDDI receivers and receiver systems employing optical-to-electrical conversion.
The HMC799LP3E TIA provides a single-ended output voltage that is proportional to an applied current at its input port; typically provided by a photodiode. Operating from a single +5V supply, the HMC799LP3E draws only 70 mA, and features very low input referred noise of 150 nA RMS over a 700 MHz analog bandwidth, which is ideal for laser sensors and RF/Fiber applications. The combination of the HMC799LP3E TIA’s very large electrical dynamic range of 65 dB, and 10 kOhm or 80 dB-Ohms transimpedance translate into excellent sensitivity at higher data rates. In fully saturated mode, the output voltage swings up to 1 Vp-p.
The output of the HMC799LP3E is internally matched to 50 Ohms, and requires no external matching. The HMC799LP3E also exhibits excellent gain and output power stability over its full operating temperature range, while requiring a minimal number of external components.
Housed in a compact RoHS compliant 3 x 3 mm SMT package and specified for operation from -40°C to +85°C, the HMC799LP3E complements the previously released HMC690 10 Gbps TIA.
Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order. Released data sheets are available on our website, just click the URL below our logo on this page.
