尺寸

一个 1600-2200 MHz 频率下变频至 200-800 MHz混频器 is an RF (无线电频率) device that takes input signals in the 1600-2200 MHz frequency range and converts (或者 “down-converts”) them to a lower frequency range of 200-800 MHz.

它是如何运作的:

• This is typically achieved using a frequency mixer combined with a 本地振荡器 (洛).

• The mixer combines the input RF signal with the LO signal to produce sum and difference frequencies.

• 一个 带通滤波器 is then used to select the desired lower frequency output (200-800 MHz) and reject the unwanted signals.

目的 / 应用领域:

Our COFDM transmitter supports 50-6000MHz, but the wireless video receiver can only support 170-860MHz. 此时, you need to add this frequency downconverter to the receiver.

• Satellite communications: Down-converting high-frequency satellite signals to a lower frequency for easier processing.

• Surveillance and signal monitoring: Converting signals to a frequency range compatible with receivers or spectrum analyzers.

• Wireless communication systems: When a receiver cannot directly handle high frequencies, down-conversion brings the signal to a usable range.

• Radar and electronic warfare: For processing signals in different frequency bands.

例子:

If you input a 1800 MHz信号, the mixer could use an LO (for example at 1600 MHz), producing a difference of:

which falls within the 200-800 MHz output range.
