The AFE79-LMH9-EVM evaluation module (EVM) is a board for evaluating the performance of the AFE79xx family of integrated RF sampling transceivers interfaced with the LMH9xxx family of active baluns. The AFE79-LMH9-EVM showcases the AFE7920, LMH9126, LMH9226, LMH9135, and LMH9235. The device is well suited to support the requirements of next generation 5G massive MIMO active antenna systems while interfacing output of a transceiver and driving power amplifier (PA) input. By default, the board is setup for 100-Ω differential input matching and 50-Ω single-ended output matching for easy interface with 50-Ω test equipment. The EVM is ready to connect to +3.3-V power supply, signal source and test instruments through the use of onboard connectors.
Features
- 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
