Input Buffer @
The input buffer has about 6 dB of gain to compensate for the loss incurred by the output
driver in A4A6A2, which converts the 21.4 MHz IF signal into a 500 system.
Output Driver @
The 21.4 MHz IF signal goes to the output driver, where it is converted to a 50R system
(6 dB loss) and sent to A4A6Al.
