Description

A wideband single-ended to differential conversion reference design in both DC- and AC- coupled applications is presented. The design evaluates the performance of the LMH5401 and LMH6401 cascade and offers insight into the design.

Features
  • 4.5GHz bandwidth with 30dB maximum total voltage gain
  • Digitally-controlled gain range of 32dB in 1dB steps
  • 50-Ω Input DC- or AC-coupled single-ended to differential conversion
  • Output IP3 at RL = 200Ω:
    • 40dBm at 500MHz
    • 33dBm at 1GHz
  • Output common-mode control capability: VMID ± 0.5V
  • Compact design ideal for portable application with PD = 645mW
