Characteristics …continued
VP =5V[1]; Tamb =25 °C; 8 MHz system; see Table 34 and Table 35; CW test input signal is used for specication;
Vi(IF) = 10 mV (RMS); fIF = 36 MHz for low IF output of 5 MHz; IF input from 50 via broadband transformer 1 : 1;
gain controlled amplier adjusted to typical specied output level; measurements taken in test circuit of
Figure 50 and Figure 51 with 4 MHz crystal oscillator reference; unless otherwise specied.
