•Datasheet: 350-MHz High Gain Near-Infrared APD Photoreceiver Engineered For Low Excess Shot Noise: Voxtel RDP1-NJAC Series

The industry's highest-sensitivity near infrared APD-TIA receiver, integrating the highest-gain and lowest-excess-noise InGaAs single-carrier multiplication APDs (SCM-APDs) with a 350-MHz transimpedance amplifier (TIA) and thermoelectric cooler (TEC) in a hermetic package.

The RDP1-NJAC is a low-noise, high-gain photoreceiver based on Voxtel's VFP-1000 series of single-carrier multiplication APDs (SCM-APDs). The combination of a low-noise SCM-APD with a low-noise transimpedance amplifier (TIA) produces a photoreceiver with industry-leading noise levels and maximum bandwidth.

Voxtel's SCM-APDs are photodetectors that exceed the capabilities of conventional avalanche photodiodes (APDs) in both gain and noise performance. The Siletz series of SCM-APDs has a very low effective ratio of ionization coefficients (keff < 0.02), and can be operated with low excess noise F(M) ~  2 up to gain M = 30, and with usable linear-mode gain typically above M = 100. By contrast, standard telecom NIR APDs are generally not useful above M = 15, and carry a much greater noise penalty (k = 0.4; F(M) > 7 at M = 15).

The RDP1-NJAC is also available with optional fiber-optic coupling. Please contact Voxtel, Inc for details.
