• Reactive multipliers have a disadvantage that they cannot be used at very high frequencies and they become less efficient.
• The major drawback of frequency multipliers is that they have:
• A major disadvantage of frequency multipliers is that they multiply the noise factor along with frequency.
• For a resistive frequency multiplier of multiplication factor 2, the maximum theoretical conversion efficiency is:
• Oscillators operating at millimeter wavelength are difficult to realize and are also less efficient.
• If the normalized load impedance of a transmission line is 2, then the reflection co- efficient is:
• The electrical size of antenna is increased by antenna array to avoid size lobes compared to single antenna.
• Klystron amplifiers have high noise output as compared to crossed field amplifiers.
•              antennas have gain less than reflector antennas but have more lenient tolerance on surfaces.
• Bandwidth of balanced amplifier can be an octave or more, but is limited by the bandwidth of the coupler.
