470 THE RECEIVIArG SYSTEM—RADAR RECEIVERS [SEC. 12.11 cavity. This phase shift is detected in the phase-comparison tube VT by applying the amplified crystal output to the control grid and the audio oscillator output to the suppressor grid. Both grids are biased to cutoff, so that no current flows in the tube unless the signals are in phase. The circuit is so arranged that the 180° shift in phase of the audio signal produces phase agreement, thereby providing pulses of plate current on alternate half cycles of the audio signal. These pulses, further amplified in Vs, then trigger thyratron V4 to stop the sweep. The change from search to beacon operation is performed remotely by relays which switch the grid input to V~, switch from the reflector voltage-control potentiometer PI to Pz, change over the plate power from the search to the beacon local oscillator, and superpose the sinusoidal modulation on the sawtooth. Switch S1 enables a maintenance man to tune the local oscillators manually to the proper frequencies for signal reception with P1 and Pt (for the search or beacon local oscillators respectively), and then to revert to AFC operation centered at the correct frequency. This switch is spring-loaded so that the circuit cannot be left on manual tuning. Jacks are provided at “which the radar AFC crystal current and the beacon AFC crystal current can be measured. A pin-jack test point is provided at the grid of Vs to aid in aligning the discriminator, and another at the plate of Vs for checking the control signals to the thyratron. This AFC unit requires a power source supplying 5 ma at +300 volts, 23.5 ma at +105 volts, 2 ma at – 300 volts, 1.55 amp at 6.3 volts, and 0.8 amp at 6.3 volts at —225 volts from ground. N’one of these voltages needs to be regulated, although the plate voltages must be well filtered. 12.11. An Extremely Wideband Receiver.—The receiver shown in Figs. 12.22 and 12.23 is a good example of a design for a receiver having a very wide bandwidth. It was designed for a 3-cm radar system with a O.l~psec pulse width. In order to reproduce such short pulses and still maintain a good signal-to-noise ratio, an i-f bandwidth of at least 10 Me/see is required; the bandwidth of the receiver is 12.5 Me/see. The i-f amplifier consists of 12 stages, 6A’K5 tubes being used in all but the second. The intermediate frequency is 60 Me/see, the total gain being approximately 120 db. An intermediate frequency of 60 Me/see instead of 30 Me/see was chosen for two reasons. First, fairly tight coupling is required between the primary and secondary of the i-f transformers to attain wide bandwidths. It is easier to make this coupling tight at 60 Me/see than at 30 Me/see. Second, the AFC operation is more certain at the higher frequency. The AFC circuit can lock the local oscillator on either side of the transmitter, provided the local oscillator is producing power at both frequencies. However, since the correct beat frequency is produced
