Intermediate-frequency amplifier consists of 2-stages amplifier, output buffer with tunable gain and two LDO voltage regulators. Each stage of the amplifier has differential input and output. Gain is sequentially reduced from the buffer to the IFA first stage. Also gain can be set manually. Frequency range is 60...83 MHz.
