2020年2月23日 · The well-known mixer NE612 (NXP) will be compared to an AN612 (Matsushita/Panasonic) mixer that has been unsoldered from an old CB-SSB-radio. Comparison will include output voltage level and spectroscopic analysis of a 9MHz SSB signal.

The NE/SA612A is a low-power VHF monolithic double-balanced mixer with on-board oscillator and voltage regulator. It is intended for low cost, low power communication systems with signal frequencies to 500MHz and local oscillator frequencies as high as 200MHz.

The NE612 is an integrated circuit for processing of signals, such as in the transmission of radio signals. It consists of an oscillator and a mixer. [1] It can handle signal frequencies of up to 500 MHz and local oscillator frequencies of up to 200 MHz.

VFO is mixed with 4.0 Mhz. to get the desired 7.0 Mhz signal. The term "heterodyne" refers to the mixing function, where two different frequencies are combined in a non-linear way to generate an output waveform of a different frequency.

2024年1月6日 · ne602混频器在许多业余电路中广为人知，今年将与其兄弟 ne612、sa602、sa612 一起停产。 因此，是时候寻找替代方案并了解此类芯片的工作原理了。 混合：加法还是乘法？

2014年1月27日 · Being a ham operator I'm always on the lookout for new radio related projects. This time I investigated the properties of direct conversion receivers using the cheap and widely available NE612 balanced mixer IC. There are four different versions of this chip NE602, NE612, SA602 and SA612.

NE/SA 602 und NE 612 von Philips sind in tegrierte doppelt-symmetrische Low-Power-Mischer mit Eingangsverstärker, Oszillator inklusive Puffer und tempera-turkompensiertem Spannungsregler.

2020年1月13日 · The NE612 is an integrated circuit which contains a balanced mixer with its own on-board local oscillator and voltage regulator. The mixer can provide up to 18dB of gain at 45 Mhz, and the local oscillator will operate up to 200 Mhz.

The NE612, also known as the NE612A, is a versatile analog multiplier and mixer IC that is widely used in radio frequency (RF) and intermediate frequency (IF) applications. At its core, the NE612 functions as a balanced modulator and a mixer, allowing for the combination of multiple input signals and the generation of an output signal with ...

2022年7月11日 · ne602和ne612的区别是：1、NE612是流行的NE602芯片的子代，它包含吉尔伯特单元混频器和振荡器，使得DIY接收器比以往更容易。 2、ne602的输入动态范没有ne 百度首页
