Surface Acoustic Wave (SAW) filters are essential components in modern communication systems. The B39162B3528U510 is a general purpose SAW filter for use in a variety of RF applications. This component is manufactured by EPCOS and is used in a range of different wireless applications, including mobile phone, cordless phone, WLAN and Bluetooth. It is also suitable for a variety of other communications applications.

The B39162B3528U510 is a high performance SAW filter which offers excellent selectivity and insertion loss in the 2.2 to 2.4GHz frequency range. It has a centre frequency of 2.3GHz, a pass band width of 25MHz and an insertion loss of 1dB. It has a rejection of up to 80dB at frequencies outside of the pass band. The device is designed to operate in temperatures from -40 to +85°C and has an operating voltage of 3.3 Volts. The device has a very low profile of just 0.5mm.

The B39162B3528U510 is packaged in a miniature 4-pin top flattened type that is suitable for SMT reflow soldering. The electrical and structural performance of the device is tested to ensure compatibility with the European RoHS directive and is classified as a “Green” product.

The B39162B3528U510 uses so-called surface acoustic wave (SAW) technology which is based on the propagation of surface acoustic waves along a piezoelectric substrate. The surface wave is generated by applying a high-frequency voltage between two electrodes on the substrate. The substrate is usually made of quartz or lithium niobate and is composed of two inter-digital transducers (IDT). The SAW filter consists of the two IDTs and a pair of reflecting electrodes which reflect the surface acoustic wave back and forth between the two IDTs.

When an incoming signal is applied to the filter, the surface acoustic wave will propagate between the two IDTs. The frequency of the incoming signal is selectively passed through the filter while other frequencies are rejected, thus reducing the total signal noise. The output of the filter will consist of the desired signals while the frequency components outside the pass-band are suppressed. This process is known as frequency selection.

In conclusion, the B39162B3528U510 is a dual-port SAW filter with a centre frequency of 2.3GHz and a passband of 25MHz. It is suitable for a variety of different wireless applications and is RoHS compliant. The device uses surface acoustic wave technology to provide an excellent selectivity and insertion loss with a low profile of just 0.5mm. This device is a great choice for any application which requires high performance filtering in the 2.2 to 2.4GHz frequency range.
