Resonators: RO3073E Application Field and Working Principle

The RO3073E is a voltage-controlled RF and microwave band-pass filter manufactured by Resonant. It has broad application in such industries as aerospace/defense, Catalina Medical Solutions, communication, CATV, instrumentation, and radar. This article will look at the characteristics and features of the RO3073E, as well as its range of applications and working principles.The RO3073E is a highly parameterized filter with a wide range of operating frequencies from 500 MHz to 6 GHz. It is housed in an aluminum case that is environmentally sealed, has a temperature range of -30°C to +85°C, and offers excellent dielectric performance. With its very low insertion loss, high out-of-band rejection, and low phase ripple, the RO3073E is a reliable and cost-effective solution for a wide range of applications.The RO3073E features a 7-pole Butterworth topology, which offers excellent performance in terms of passband return loss and stopband attenuation. It is a voltage-controlled filter that utilizes a voltage-controlled oscillator (VCO) in order to set the center frequency and bandwidth. This allows the filter to be adjusted in frequency and bandwidth by simply changing the input voltage from 0 V to +12V. The voltage-controlled filter also has a fast settling time, making it an ideal choice for applications requiring rapid response.The RO3073E can be used for multiple applications. In the aerospace industry, it can be used for aircraft navigation, tracking, and communication equipment. In the defense sector, it can be used for designing advanced radar systems. In the medical field, it can be used for medical imaging and sampling. It can also be used for CATV and broadcast television applications, for high-speed wired and wireless communication systems, and for instrumentation and test systems.The working principle of the RO3073E is based on voltage-controlled frequency tuning. The filter consists of an input stage, a variable gain amplifier (VGA), and a frequency-selective network (FSN). When the input voltage is applied, the VGA amplifies the signal, which is then fed to the FSN. The FSN consists of capacitors and inductors which form the filter components. The frequency response of this filter is determined by the resonance frequency of the filter components, which is set by the VGA. The resonant frequency can be tuned by changing the input voltage, resulting in a change in the center frequency and bandwidth of the filter.In summary, the RO3073E is a high-performance voltage-controlled filter suitable for a wide range of aerospace, defense, medical, CATV, and communication applications. It has low insertion loss and excellent out-of-band rejection, making it a reliable and cost-effective solution. Its 7-pole Butterworth topology offers excellent performance for passband return loss and stopband attenuation, and its voltage-controlled frequency tuning allows easy adjustment of the frequency and bandwidth. All these factors make the RO3073E a great choice for any application requiring an adjustable frequency and bandwidth filter.
