Texas Instruments PJ21US004624 | Demoboard LMH6401EVM

Description

The LMH6401 evaluation module (EVM) is used to evaluate the single LMH6401, digitally-controlled variable gain amplifier (DVGA) in a 16-lead high performance RF package. The EVM is designed to quickly and easily demonstrate the functionality and performance of LMH6401 across all the gain settings.The EVM is ready to connect to power supplies, signal source, USB, and test instruments through the use of onboard connectors. The board is set up for differential input and output operation. The EVM requires an external 180° phase-shifted combiner to convert single-ended signals to differential signals for use withstandard single-ended 50-Ω laboratory equipment. By default, the LMH6401EVM powers up to the –6 dB or minimum gain setting with the board supporting single-supply or split-supply operation. An USBconnector on the EVM facilitates programming of the DVGA gain registers using an FTDI USB-to-SPI bus translator chip.

Features

• Configured for split-supply operation and easily modified for single supply
• Designed for DC or AC coupled differential input and output connection
• Simple Interface to the Inputs and Outputs using SMA connectors
• USB connector and FTDI USB-to-SPI bus translator chip to successfully program the DVGA gainregisters

Typical applications

• RF Sampling Subsystems, SAW Filter Buffers and Driver, Test and Measurement, Ultra-Wideband ADC Drivers
• Defense and Radar
• Communications Receivers
