123. What component of a RADAR receiver is represented by block 48 in Fig. 8A1?
Block 48 represents the klystron, which functions as the local oscillator in the RADAR receiver. The local oscillator generates a stable microwave signal for mixing with the received echo in a superheterodyne receiver; a klystron is commonly used for this purpose at microwave frequencies.
