400MHz differential amplifier circuit with broadband transconductance operational amplifier and buffer OPA660, BUF601
Differential signal voltage VI, - VI is respectively sent to 3 feet of OPA660 internal OTA and pin 5 of +1 amplifier by 150Ω resistor and 51Ω matching resistor, then the +1 amplifier's 6 feet outputs it to 2 feet of OTA.
