23 GHz Balanced PhotoReceiver, Differential Output (BPR-23-D)

Data Sheet

The Optilab BPR-23-D series is a linear balanced photoreceiver with a configurable bandwidth up to 23 GHz.

Product Overview

The Optilab BPR-23-D series is a linear balanced photoreceiver with a configurable bandwidth up to 23 GHz. In a 14-pin mini-DIL package, BPR-23-D integrates a dual balanced PIN-photodiode (PD) array on a single chip and a linear Trans-Impedance Amplifier (TIA). It can be operated in either Manual Gain Control (MGC) mode or Automatic Gain Control (AGC) mode. Featuring differential conversion gain of 1500 V/W, an inbalanced response of less than 0.5 dB and a differential output voltage swing of up to 1200 mVpp, BPR-23-D is the idea receiver solution for DQPSK operating up to 48 Gbit/s or for low noise analog heterodyne detection. Excellent electrical and optical phase propagation is achieved by a total skew of lower than 5 ps between the balanced signal paths.
