The B39182-B7652-G210 is a Surface Acoustic Wave (SAW) filter manufactured by EPCOS, now a part of TDK. SAW filters are used to selectively filter signals within a specific frequency range, commonly found in radio frequency (RF) applications like mobile communication devices and other wireless systems.

Applications

• Radio Frequency (RF) front-end filtering.
• Intermediate Frequency (IF) filtering.
• Wireless Communication Systems (e.g., Mobile Phones, Wi-Fi).
• Remote control systems.

Features

• Center Frequency: Designed to operate at a specific center frequency, often around 1.8 GHz or similar frequencies used in mobile communication.
• Low Insertion Loss: Minimizes signal attenuation, enhancing performance.
• High Attenuation: Provides strong rejection of unwanted signals outside the passband.
• Compact Size: Enables use in small, portable devices.
• Surface Mount Technology (SMT): Facilitates automated assembly.

Benefits

• Improved Signal Quality: Enhances signal-to-noise ratio by filtering out unwanted frequencies.
• Increased Receiver Sensitivity: Low insertion loss boosts the receiver's ability to detect weak signals.
• Simplified Circuit Design: Offers a compact, integrated filtering solution.
• Cost-Effective: Efficient performance translates to lower system costs.

Technical Specifications

While exact specifications vary, typical parameters include:

Center Frequency: Approximately 1.8 GHz (check datasheet for precise value). Bandwidth: Specified range around the center frequency. Insertion Loss: Usually measured in dB. Attenuation: Measured in dB at frequencies outside the passband. Impedance: Typically 50 Ohms. Package Type: Surface Mount Device (SMD) Operating Temperature: Usually within the range of -40°C to +85°C

The B39182-B7652-G210 SAW filter is a key component in RF systems, improving signal integrity and performance. Its small size and robust characteristics make it well-suited for modern wireless applications.
