NTE1608

The NTE1608 is a specialized integrated circuit functioning as an RF mixer and amplifier, packaged in a 20-Lead DIP configuration. Designed for robust signal processing, it incorporates low-noise transistors in a cascode circuit to achieve excellent usable sensitivity. The device provides a typical RF amplifier gain of 45dB per meter while maintaining a high signal-to-noise ratio of 57dB at intermediate input frequencies.

A key design feature is its double-balanced differential mixer architecture, which effectively prevents spurious radiation and delivers 85dB typical IF interference rejection. The local oscillation output is stabilized at a low level of 350mVrms to minimize tracking errors for varactor diodes. Additionally, the part supports narrow-band signal meter applications with a typical frequency deviation of ±1.5kHz.

Electrical characteristics include a maximum supply voltage of 16V and a maximum operating current of 32mA. The component operates reliably within a temperature range of -20°C to +70°C, with storage capabilities extending from -40°C to +125°C. With a maximum allowable power dissipation of 700mW, it is suited for compact analog front-end designs requiring stable mixing and amplification performance.
