Abstract: RCA 74, 055 A preamplifier is provided which couples a television tuner to a surface acoustic wave (SAW) filter and amplifies the I.F. signals supplied by the tuner so as to overcome the signal losses of the SAW filter. The preamplifier comprises a single transistor, the gain of which may be varied to provide desired gain and noise performance for the entire tuner-SAW filter-I.F. system. The preamplifier may also include a tuned circuit which preshapes the I.F. signal response characteristic. The tuned circuit provides the preshaping by exhibiting an additional pole in the vicinity of the vestigial slope portion of the I.F. signal response characteristic.
