SAW Filters

A SAW filter, short for surface acoustic wave filter, is a type of electronic filter used in radio frequency applications. The SAW filter is based on the concept of surface-acoustic wave propagation on piezoelectric material such as quartz crystal. The filter typically consists of a resonator array, usually designed on a single piezoelectric crystal, on which the acoustic waves interact with the active transistor circuitry. By properly designing the transistors and the acoustic characteristics of the crystal, SAW filters can be tailored to provide any desired filter characteristic.

The B39142B1666U510 is one example of a SAW filter. It is a low pass filter with a passband of 500MHz-30GHz, a stopband frequency ranging from 2GHz to 30GHz, a bandwidth of 10 MHz, a 10dB signal loss at 2GHz, a minimum insertion loss of 1.5dB and a maximum insertion loss of 18dB.

The B39142B1666U510 is used in applications such as receiver front-end circuits, antenna switches, and multiplexers. It can also be used to select specific frequencies from a wider frequency range. This functionality is especially useful in cellular systems where it is important to separate various broadcast frequencies.

The B39142B1666U510 also has a number of advantages over other types of filters. One advantage is its wide operating temperature range. The B39142B1666U510 is rated for use in temperatures ranging from -40°C to +85°C, making it suitable for use in a variety of environments. It also has a high tolerance for input voltage and power levels, making it less susceptible to interference from external sources.

The working principle of the B39142B1666U510 SAW filter is based on surface acoustic wave technology. At the heart of the filter is the piezoelectric transducer, which converts electrical signals into mechanical vibrations that can be propagated along the surface of the crystal. The transducer also helps to control the filter characteristics, by changing the frequency, amplitude, and phase of the acoustic wave.

The vibrating wave interacts with the transistors in order to filter out frequencies. When a frequency within the passband of the filter is transmitted, it passes through the filter and reaches the output. Conversely, frequencies outside the passband get attenuated or blocked. The B39142B1666U510 has two transistors, one acting as an amplifier and another serving as an attenuator.

In conclusion, the B39142B1666U510 SAW filter is a versatile and reliable filter solution for radio frequency applications. It is well-suited for use in radio front-end circuits, antenna switches, multiplexers and other applications. Its working principle is based on transducer-controlled surface acoustic wave propagation on piezoelectric material, resulting in precise filtering of varied frequencies. Its wide operating temperature range and high tolerance for input voltage and power levels make it a desirable choice for a variety of applications.
