The RFFC5072ATR13 is a highly integrated downconverter manufactured by RF Micro Devices (now Qorvo). It is designed for use in satellite receiver applications. This IC converts L-band signals to a lower intermediate frequency (IF) signal, which can then be processed by a demodulator and decoder.

Applications

• Satellite Receivers
• Set-Top Boxes
• Direct Broadcast Satellite (DBS) Systems
• Satellite Radio Receivers
• VSAT (Very Small Aperture Terminal) Systems

Features

• Integrated Low Noise Amplifier (LNA): Provides high sensitivity and low noise figure.
• Image Rejection Mixer: Rejects unwanted image frequencies.
• Integrated Local Oscillator (LO): Generates the required LO signal for downconversion.
• Variable Gain Control: Allows for adjusting the gain of the downconverter.
• Low Power Consumption: Minimizes power consumption in receiver applications.
• Compact Package: Available in a small footprint package.

Benefits

• Simplified Receiver Design: Reduces the number of external components required for downconversion.
• Improved Receiver Performance: High sensitivity and low noise figure enhance receiver performance.
• Reduced System Cost: Integrated functionality lowers overall system cost.
• Smaller Form Factor: Compact package enables smaller and more compact receiver designs.
• Extended Battery Life: Low power consumption extends battery life in portable applications.

Additional Details

The RFFC5072ATR13 operates over a wide input frequency range, typically from 950 MHz to 2150 MHz (L-band). The output IF frequency can be configured to various values depending on the application requirements. The IC uses a single 3.3V power supply. It is controlled through a serial interface. The RFFC5072ATR13 provides excellent image rejection performance, minimizing the impact of unwanted signals on the receiver. The variable gain control allows for adjusting the gain of the downconverter to optimize the signal level for the demodulator. The integrated LNA provides high sensitivity and low noise figure, improving the overall receiver performance. The LO frequency is generated by an internal synthesizer, which can be programmed through the serial interface. The RFFC5072ATR13 is available in a QFN package, which offers excellent thermal performance and minimizes parasitic inductance.
