A mixer includes a first terminal and a second terminal forming a first input port for receiving a first signal having a first frequency; a second input port for receiving a second signal having a second frequency; a mixer output port for a resulting signal; a first group of valves having their control inputs coupled to the first terminal for receiving the first signal; a second group of valves having their control inputs coupled to the second terminal for receiving the first signal; and a third group of two valves having their control inputs coupled for receiving the second signal. The valves co-operate such that in operation the mixer produces the resulting signal responsive to the first and second signals. The mixer also includes at least one passive low pass filter having an inductor, the low pass filter being connected to the control input of a valve in the first and second groups.
