Communications receiver

Commercial communications receivers are characterized by high stability and reliability of performance, and are generally adapted for remote control and monitoring.

Typically, a communications receiver is of the superheterodyne type in double, triple or, more rarely, quad conversion.

Communication receivers are suited for operation near powerful transmitting facilities and so must have good internal shielding, and effective front-end filtering.

Rejection of unwanted signals (images, intermodulation products) will typically be much greater than a consumer-type general coverage or broadcast receiver.
