The NE602 device is a monolithic integrated circuit containing a dou ble-balanced mixer (DBM) and on in ternal oscillator circuit. The DBM hos balanced inputs (pins 1 and 2). bal anced outputs (pins 4 and 5). and con operate at up to 500 MHz. The internal oscillator circuit provides· an emitter connection and a base connection to the outside world.

The NE602 is an fantastic integrated circuit, complete one chip radio! The NE602/SA602/NE612/SA612 family, all have inside, an oscillator and double-balanced mixer. It can be used too as the...

SINGLE-CHIP FREQUENCY CONVERTER Introducing a general-purpose single-chip frequency converter which should greatly simplify your RF designs. The combination of the differential amplifier and mixer in the NE602 is known as a Gilbert cell. The mixer has on-board voltage regulation, and draws 2.5—3 mA at 4.5—8 volts. For

2022年12月30日 · There are plenty of active mixer chips, or even analog switches if you want to go very low. Get a surface mount to DIP adapter and solder the chip on to it. SOIC surface mount in particular is easy to solder. SSOP is also easy with the right technique and a little practice.

The circuit is of an 80 meter band one chip DC receiver, (excluding the AF stage). As you can see the design utilises the NE602 as VXO/mixer. It is economical with components. I have spent a little time optimising the design and this is my latest version. The RFC value is 33mH and may be a bit over the top for the job.

The NE602 uses a double-balanced mixer, producing only the sum and difference frequencies, not that of the RF input or LO. You can thus connect the output of an NE602 directly to a receiver without overloading it. With a conventional mixer, you'd have to add a tuned LC circuit to eliminate the LO output. The NE602 LO is also

2024年11月4日 · I'm trying to understand how the Colpitts LC tank circuit in Philips' application note AN1982 for the NE602 works. Both the application note and the datasheet show that pins 6 and 7 provide access ...

the Philips Semiconductors NE602 mixer/os-cillator provides mixer operation beyond 500MHz, a versatile oscillator capable of op - eration to 200MHz, and conversion gain, with only 2.5mA total current consumption. With a proper understanding of the oscillator design considerations, the NE602 can be put to work quickly in many applications ...
