Device Overview

The LFTX daughterboard utilizes two high-speed operational amplifiers to allow transmission from 0-30 MHz. The LFTX is ideal for applications in the HF band, or for applications using an external front end to up-convert and amplify the intermediate signal. The outputs of the LFTX can be processed independently, or as a single I/Q pair. Example applications include HF communications, radios with external front ends and direct signal generation below 30 MHz.
