METHOD AND APPARATUS FOR CONTROLLING FREQUENCY OF METHOD AND APPARATUS FOR CONTROLLING FREQUENCY OF A MULTI-CHANNEL TRANSMITTER A MULTI-CHANNEL TRANSMITTER |
摘要 |
A method an apparatus for controlling frequency of a multi-channel transmitter. A reference frequency is generated and emitted to a thermally stable frequency discriminator. The thermally stable frequency discriminator emits a dc voltage to a plurality of individual oscillators. The individual oscillators in continuous wave mode or modulated by baseband signals are combined into a multi-channel signal at an intermediate range of frequencies. The multi-channel intermediate range of frequencies are preferably amplified and emitted as an output signal. At relatively lower frequencies, such as 4-6 GHz, up-conversion of the output signal is not necessary. At relatively higher frequencies, an up-converter can be used to employ a second thermally stable frequency discriminator. |
