Differential amplifier circuit diagram with 20MHZ bandwidth
The circuit consists of two CA3005 RF amplifiers, the gain is decided by the ratio Rr / Ri. Capacitors C1, C2 are used to improve the bandwidth to prevent high-frequency self-excitation. Error of resistors is 1%, and the bandwidth is 200MHz, and time delay is 20μs.
