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.

2016年9月13日 · 由于 ne602 采用双平衡混频器并具有振荡器， 故用作超外差式接收机的前端电路， 不仅使用方便而且具有很好的信噪比和三阶互调指标。 在 45MHz 下的噪声系数典型值为 5dB。

2008年10月4日 · 如今，原为行动无线电话机而设计的 IC，NE602，应用广泛，也可能成为紧接 555 之后的另一只热门 IC。 NE602 是内含本地振荡的单晶片变频器，在超外差式接收机或发射机中，它可以扮演 变频器的角色，独挑中频线路。 除此之外，他也可以供做简易的频谱分析仪。 从极低的频率到极高频率范围内的接收 机中，都可拿它用做接收机的前端 (FRONT ENDED) 线路，甚至，以此 IC 为中心， 便可以单独地完成一部简易的接收机。 功能强，是它被广泛应用的 …

NE602 的 6、7 脚分别是内部振荡管的基极和发射极，它们可与外接元件构成晶振或 LC 本振，振荡频率最高可 达 200MHz， 混频器最高可达 500MHZ。 如果要求本振频率高于 200MHz， 可使用外部本振并将它的输出信号耦合到 NE602 的 6 脚，但注入的信号电平不得超过﹣13dBm（即 1.5KΩ电阻上 250mV） 。 图 7A 的本振是简单的考毕兹（Colpitts）晶体振荡器。

2002年2月18日 · The NE602 is a low-power VHF monolithic double-balanced mixer with input amplifier, on-board oscillator, and voltage regulator. It is intended for high performance, low power communication systems. The guaranteed parameters of the SA602A make this device particularly well suited for cellular radio applications.

NE602 gives much better perfor- mance than the one-transistor mixer commonly found in receivers. The input and output impedances of the NE602 are about 1.5K at low frequencies, and decrease with in- creasing frequency. The input signal should be weak to prevent harmonics; the third-order intercept point is for a 15 dBm input, but the recommended

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 ...
