Detailed Description

A dialog for calculating image frequencies in dual-conversion superheterodyne receivers.

This calculator determines the local oscillator (LO) frequencies and image frequencies for both stages of a dual-conversion receiver. It uses low-side injection for both stages.

For each conversion stage:

• LO frequency: f_LO = f_in - f_out
• Image frequency: f_IM = f_in - 2*f_out

Stage 1: RF → 1st IF

• f_LO1 = f_RF - f_IF1
• f_IM1 = f_LO1 - f_IF1

Stage 2: 1st IF → 2nd IF

• f_LO2 = f_IF1 - f_IF2
• f_IM2 = f_LO2 - f_IF2
