MN4765A
This product has been discontinued Replacement Model(s) : MN4765B
Overview

The MN4765A is a characterized, unamplified photodiode module. It is used as an optical receiver with the Anritsu MS4640B VectorStar series VNAs to perform highly accurate and stable optoelectronic measurements of both modulators (E/O) and photoreceivers (O/E) to 65 GHz.

The MN4765A consists of an InGaAs photodiode that converts modulated optical signals to electrical signals, and includes additional circuitry for temperature and bias stability. The photodiode has exceptional bandwidth response to 65 GHz and a typical responsivity of 0.7A/W. The MN4765A is characterized for 1550 nm in both magnitude and phase using a NIST derived calibration standard.

  • Fast and accurate optoelectronic measurements- The MS4640B VectorStar series VNAs, when calibrated using the MN4765A module, enable error-corrected Transfer Function, Group Delay, and Return Loss measurements of E/O and O/E components and subsystems
  • National Institute of Standards and Technology derived characterization to 65 GHz - Magnitude and phase characterization is obtained using a primary standard characterized by NIST and held in the Anritsu Calibration Lab. The magnitude and phase data is provided on a diskette with the module
  • Temperature Stable - The MN4765A is thermally stabilized to eliminate drift in photodiode performance over temperature
  • Internal Biasing - Accurate bias voltage to the photodiode is maintained internally. An external, multi-country, AC adapter is included for easy operation
  • High Linearity - Linear operating range to +6 dBm for transfer function measurement uncertainties of <0.5 dB at 50 GHz and <1 dB at 65 GHz
  • High Responsivity - 0.7 A/W and 0.5 A/W (Typical specification for MN4765B-0070 and -0110 respectively)
