SAW Components B3853 is a low-loss IF filter for CDMA base stations. It is temperature stable and comes in a ceramic SMD package. It can be operated in unbalanced or balanced mode.
This document is a data sheet for the EPCOS B3853, a surface acoustic wave (SAW) component designed as a low-loss intermediate frequency (IF) filter operating at 141.0 MHz. It features a ceramic DCC18 SMD package and supports both unbalanced and balanced operation with gold-plated terminals.
The datasheet provides detailed electrical characteristics, including nominal frequency, insertion attenuation, bandwidth, amplitude ripple, phase linearity, and group delay specifications. It also lists maximum ratings for temperature and voltage, along with a matching network circuit diagram to achieve 50 Ohm impedance.
| Minimum insertion attenuation | 11.0 dB |
|---|---|
| Bandwidth (3dB) | 7548 kHz |
| Operating temperature range | -40 to +85 °C |
| DC voltage maximum | 5 V |
Both the source and load must be 50 ohms with an external matching network.
