64 dB Intermediate frequency amplifier with wide gain range

Intermediate frequency amplifier consists of 3-stage amplifier with tunable gain, AGC system, linear output buffer for differential analog output, analog-digital converter for 1.5-bit digital output. Each stage of the amplifier has differential input and output. Gain is sequentially reduced from the last stage to the first stage.Also gain can be fixed.
Frequency range is 2.5...22.5 MHz. Maximum gain is 64...83 MHz. AGC range 0…64 dB.
