Moreover, the interphone can realize communication among group members, so the interphone becomes a very valuable portable communication tool for users such as police, emergency service, industry and commerce and the like.

The receiving portion of the intercom mixes the amplified signal from the radio frequency with a first local oscillator signal from the phase locked loop frequency synthesizer circuit at a first mixer and generates a first intermediate frequency signal. The first intermediate frequency signal further eliminates clutter signals of adjacent channels through a crystal filter. The filtered first intermediate frequency signal enters an intermediate frequency processing chip and is mixed with a second local oscillation signal again to generate a second intermediate frequency signal, and the second intermediate frequency signal is amplified and frequency-discriminated after useless spurious signals are filtered by a ceramic filter to generate an audio signal. The audio signal enters a volume control circuit and a power amplifier for amplification through circuits such as amplification, band-pass filter and de-emphasis, and drives a loudspeaker to obtain information required by people.
