Optical Receivers
CMC Electronics offers optical receivers with InGaAs or Si APDs in a 12-lead TO-8 package. These receivers are designed with low-noise GasFET input transimpedance amplifier; also with amplifier and built-in thermoelectric cooler. Each amplifier has an overload input protection circuit for fast recovery. These modules are designed for a 100-ohm output load connection ( AC or DC coupled, as required by design)
Key features include:
- Low noise preamp
- Bandwidth ranges: 50MHz to 300 MHz
- Large CW voltage swing
- Fast overload recovery
- APD on built-in Internal TEC
- Thermistor T˚ sensor
Customization such as bandwidth selection, NEP screening, responsivity optimization and packaging including fiber optic or optical connector are available to fit your system design needs.
In addition to the APD receivers, CMC Electronics also offers dual wavelength InGaAs PIN Quadrant detector for operation over a 950nm-1650nm band. The detector includes four internal transimpedance amplifiers (TIAs) in a hermetically sealed package
- 1mm quadrant detector
- 90kΩ Zt with 30MHz bandwidth
- Higher bandwidth available
- Four TIAs
- Large CW voltage swing
