Dpg-200 Vacuum Transducer with

  • -10dBm LO Power Consumption: Provides +24dBm third order intercept point, can achieve -10dBm LO power consumption, without high power LO drivers, there are no corresponding shielding and isolation problems, can improve system performance and reduce costs.
  • Single Power Supply: The mixer module is designed to be powered by a single power supply, and the RF, IF and LO ports have DC isolation capacitors for easy use.
  • 10.3dB SSB Noise Figure at 70MHz: With the output amplifier and optimal source impedance of this mixer module, the SSB noise figure is 10.3dB at 70MHz. There is no insertion loss, no external duplexer, and no passive termination.
  • Low Distortion and Wide Dynamic Range: AD831 is a low distortion, wide dynamic range, single chip mixer, very practical.
  • Wide Application: Suitable for applications such as RF‑IF down conversion in HF and VHF receivers, second mixer in base stations, DC baseband conversion, quadrature modulation and demodulation, and Doppler shift detection in imaging.
