Wewant to connect the AD9361 Tx positive output directly to our load (via a cap) and thenegative output directly to 50 ohm resistor(via a cap) without any balun. Is itpossible?
Kindly refer UG-570 , page 69.
The Tx Outputs are differential. The Tx differential output port is a medium signal device. Therefore, impedance matching is based on load-pull techniques. Tx output differential load impedance represents the best compromise between the maximum output power delivered and the highest possible third-order linearity (OIP3). Hence a Balun is required for proper impedance matching.
