AM Radio Receiver IF Board PCB Layout Feedback and Suitability for Didactic Use

The discussion centers on the PCB layout design of an AM radio receiver's intermediate frequency (IF) board, focusing on its suitability for didactic purposes. The design uses through-hole components, primarily two- and three-leaded parts, with one five-leaded component, arranged to clearly separate functional blocks for educational clarity. The IF frequencies considered are 455 kHz and 10.7 MHz, with questions about optimal ground plane and power plane separation, trace width, and length. Recommendations include using a two-sided PCB with the component side as a ground plane and traces on the solder side, or a four-layer PCB to separate power and ground planes for improved decoupling and reduced noise. For prototyping, a single-sided PCB with unetched copper as a ground plane is suggested. Emphasis is placed on minimizing lead and trace lengths for bypass capacitors to reduce serial inductance. The design is slower than modern logic circuits, so a full power plane may not be necessary. The user also separated the ground and power planes on their PCB and arranged circuits for easy observation. A request for schematic details and clarification on the use of 10.7 MHz IF in AM receivers was noted. An example of a high-frequency ECL flip-flop (MC10EL52) clocked at 540 MHz was mentioned in a related context.
