Oscillators

Oscillators refer to a class of electronic circuits, which convert direct current to a periodic alternating signal; they are among the earliest electronic circuits used in all kinds of electronic systems. The ECS-1618-120-BN-TR Oscillator is a fixed tuned oscillator developed for applications in a wide frequency band, from audio to microwave frequencies. This particular oscillator is designed to provide stable signal with undesired modulated components.

Application field and Working Principle

The ECS-1618-120-BN-TR Oscillator is widely used in mobile communications between 20MHz and 3GHz frequency bands, in both high-volume consumer applications and embedded communications products. It can be employed in both 2G and 3G mobile tuners as signal sources or local oscillators in aircraft and shipboard communication systems. With a low profile package design, the oscillator is tailored for space-confined applications.

This oscillator uses an in-series resonant circuit formed by lumped components, operating as a tank circuit. This tank circuit produces a signal at a frequency determined by components values. The frequency range is determined by the Q and resonance value of the tank circuit. The buffer amplifier at the output of the tank circuit is designed for balancing the output voltage and its oscillating frequency, along with the stability of the frequency.

The operating principle of the ECS-1618-120-BN-TR Oscillator can be explained in simpler terms. The circuit consists of a reference frequency produced by a crystal oscillator and a frequency multiplicator, which increases the reference frequency by a factor of 5. This energy input is amplified by an amplifier stage, which feeds the tank circuit. The tank circuit, consisting of capacitors and inductors, is essential for producing a frequency-selective response, while the amplifier provides the necessary gain and power output.

The ECS-1618-120-BN-TR Oscillator offers low operational frequencies as low as 20MHz, and its design provides high harmonic suppression and pulse amplitude modulation. With its rugged design and high reliability, this oscillator is a reliable choice for a wide range of communication applications.
