In RF tuning, _________ provides the final up conversion to the microwave frequency?(a) Fixed-frequency local oscillator(b) RF frequency synthesizer(c) Quartz oscillator(d) Magnetic oscillator |
|
Answer» Correct answer is (b) RF frequency synthesizer For explanation I would say: In RF tuning, a mixer fed by a fixed-frequency local oscillator performs an initial up conversion to 700 MHz. Then a sophisticated RF frequency synthesizer applied to a second mixer provides up conversion to the final microwave frequency. |
