Oscillators are devices or circuits that generate an output signal without an input signal, automatically producing a waveform at a regular frequency. Oscillators find broad application, from providing time base signals required for digital systems to generations of radio frequency signals for broadcast communications and RADAR systems. An example of an oscillator is the 550BM1400M00DGR, a planar monolithic microwave integrated circuit (PMIMIC) oscillator from Amtec Microwave.

Applications of the 550BM1400M00DGR

Amtec Microwave\'s 550BM1400M00DGR is a low-cost, highly reliable PLL oscillator suitable for applications such as broadcast television, radio base stations, cellular networks, WiFi, RADAR and other wireless communication systems. The unit is a PLL (Phase-Locked Loop) oscillator operating in the C-Band frequency range. It has a single output stage with a frequency range of 1.8 MHz to 1400 MHz and an output power of 15 mW (min) to 30 mW (max) over a temperature range of -50°C to +80°C. The unit is housed in a low-profile, surface-mount package measuring just 5 mm x 7 mm x 0.9 mm, making it ideal for applications requiring a compact form factor. The unit has a low phase noise of -98 dBc/Hz @10MHz offset and an excellent harmonic suppression of -60dBc or better.

Working Principle of the 550BM1400M00DGR

The 550BM1400M00DGR is a PLL oscillator, which means it relies on the principle of phase-locking to generate its output signal. Phase-locking is a process in which the oscillator uses an external signal to control or “lock” the phase of its output signal. When an external signal is supplied to the PLL, it compares this signal to its own output signal and adjusts the phase in order to maintain the two signals in phase-alignment. The result is an output signal with very low phase noise, in which the signal’s frequency is locked to the phase of the external reference signal. In the case of the 550BM1400M00DGR, a feedback path is used to compare the output of the PLL to its reference input, and a voltage control loop is used to control the output frequency.

Conclusion

The Amtec 550BM1400M00DGR is a versatile and highly-reliable PLL oscillator suitable for broadcast television, radio base stations, cellular networks, WiFi, RADAR and other wireless communication systems. It has a single output stage operating in the range of 1.8 MHz to 1400 MHz with low phase noise and excellent harmonic suppression. The unit’s PLL technology provides superior frequency stability, with its output signal locked to the phase of an external reference signal. This technology makes the 550BM1400M00DGR an excellent choice for applications requiring accurate and reliable signal generation.
