NE602 primer
The Signetics (philips Components) NE602/SA602 is a monolithic integrated circuit containing a double balanced mixer (DBM), an oscillator, and an internal voltage regulator in a single eight-pin package. The DBM operates to 500 MHz, while the internal oscillator works to 200 MHz. The primary uses of the NE602/SA602 are in HF and VHF receivers, frequency converters and frequency translators. The device can also be used as a signal generator in many popular inductor-capacitor (L-C) based variable frequency oscillator (WO), piezoelectric crystal (XTAL), or swept-frequency, configurations. In this article we will explore the various configurations for the d.c. power supply, the RF input, the local oscillator end the output circuits. We will also examine certain applications of the device.
