(C)Element 8-22 Amplifiers Flashcards
1
Q
Overcoupling in a RADAR receiver will cause?
A
oscillations
2
Q
The usual intermediate frequency of a shipboard RADAR unit is:
A
30 or 60 MHz
3
Q
The I.F. amplifier bandwidth is:
A
wide for short ranges and narrow for long ranges
4
Q
A logarithmic IF amplifier is preferable to linear IF amplifier in a RADAR receiver because it:
A
has a greater dynamic range
5
Q
the high gain IF amplifiers in a RADAR receiver may amplify a 2 microvolt input signal to an output level of 2 volts. This amount of amplification represents a gain of:
A
120 dB
6
Q
In a RADAR receiver the AGC and IAGC can vary between:
A
20 and 40 dB
