3.55 GHz single ended in to differential out amplifier evaluation module


Order now


The LMH9235-EVM evaluation module (EVM) is used to evaluate the LMH9235 device, which is a single-ended input to differential output 18-dB gain block amplifier available in 2x2mm2 12-pin RRL package. The device is well suited to support requirements for the next generation 5G m-MIMO Active antenna system while interfacing with the input of transceiver. The EVM is designed to quickly demonstrate the functionality and performance of the LMH9235 for 3.55 GHz receive application with 700 MHz of 1-dB BW. By default, the board is setup for 50-Ω single-ended input matching and 100-Ω differential output matching for easy interface with 50-Ω test equipment. The EVM is ready to connect to +3.3V power supply, signal source, and test instruments through the use of onboard connectors.

  • Operates on single 3.3-V supply
  • Designed for differential 100-Ω input matching and single-ended 50-Ω output matching interface
  • Simple interface to the inputs and output through on-board SMA connectors
  • Power down option available on board using jumper connector
