Application field

The SIT1602BC-22-28E-3.570000G oscillator module can be used in many applications such as frequency synthesized communication systems, radio receiver, Radar, auto tracking systems, satellite navigation, mobile communication systems, and wireless communication systems. It can also be used in military applications like Battlefield communication systems, Satellite communication systems, etc. It is widely used in the RF industry because of its low phase noise, low power consumption, and wide frequency range.

Working Principle

The SIT1602BC-22-28E-3.570000G oscillator module is a microwave oscillator wherein two low noise amplifiers and two filters are used to create the high-frequency oscillations. These amplifiers are designed to provide a large gain capacity, forcing the signal to oscillate to a much larger amplitude than in other oscillators, which enables the oscillator to reach the desirable frequency and power levels. These amplifiers also act as the inherently narrow feedback effect from which the high-stability and phase noise are derived.

This module also utilizes a dual-loop temperature compensation technique to reduce the frequency deviation caused by temperature changes. This method eliminates the need for costly external capacitors that are normally used to tighten the frequency stability. This feature helps lower the module’s cost while keeping its performance. The SIT1602BC-22-28E-3.570000G oscillator module also uses a unique on-board temperature sensor to compensate the thermal effects of the device. It also ensures excellent phase noise performance in broad temperature ranges such as -40°C~85°C.
