Abstract: A multiple channel radio frequency repeater has a receive port for receiving an input signal from a first antenna and a transmit port for transmitting a frequency shifted output signal to a second antenna. An input bandpass filter is located at the input port. A low noise amplifier follows the input bandpass filter for amplifying all signals within the input bandwidth. A plurality of channel filters divide the input signal into a plurality of channel signals. A local oscillator generates a local oscillator (LO) signal. There is a mixer corresponding to each channel, each mixer has an input port, an output put port and an LO port. The LO port is coupled to the local oscillator. An Automatic Gain Control (AGC) amplifier is between each channel filter and each mixer for adjusting the channel signal level to the mixer input port to assure that each mixer has the same level amplified channel signal.
