NOTE: 1. The generator source impedance is 50 , but the SA615 input impedance at Pin 18 is 1500 . As a result, IF level refers to the actual signal that enters the SA615 input (Pin 8) which is about 21dB less than the ”available power” at the generator. -
Page 5: Circuit Description
High performance low power mixer FM IF system CIRCUIT DESCRIPTION The SA615 is an IF signal processing system suitable for second IF or single conversion systems with input frequency as high as 1GHz. The bandwidth of the IF amplifier is about 40MHz, with 39.7dB(v) of gain from a 50 source. - Page 6 100nF +10% Monolithic Ceramic 10pF NPO Ceramic 100nF +10% Monolithic Ceramic 100nF +10% Monolithic Ceramic *NOTE: This value can be reduced when a battery is the power source.
