RFFC2071ATR13

Overview

The Qorvo RFFC2071ATR13 is a reconfigurable frequency conversion device integrating a fractional-N PLL synthesizer, VCO, and dual RF mixers. It supports LO frequencies from 85 MHz to 2700 MHz and RF/IF ranges of 30 MHz to 2700 MHz. Key electrical parameters include a conversion gain of -2 dB, an input IP3 of +23 dBm at 2 GHz, and a noise figure of 13 dB. The device operates on a 2.7V to 3.3V supply with a current consumption of 125 mA. Phase noise specifications are -90 dBc/Hz at 1 kHz offset and -102 dBc/Hz at 10 kHz offset, both measured at 2 GHz. It utilizes a QFN-32 (5x5 mm) package.

Feature Summary

• Integrates a fractional-N PLL synthesizer with sigma-delta modulation for ultra-fine step sizes and low spurious outputs.
• Features a temperature-compensated VCO providing stable performance across the industrial temperature range.
• Includes two high-linearity RF mixers with programmable bias currents for optimized power consumption.
• Supports full-duplex mode operation and bypass configuration for direct signal sourcing.

Applications

• LTE wireless infrastructure
• WiMAX base stations
• Point-to-point microwave radio systems
• Software-defined radio platforms

Procurement Notes

Verify the specific suffix 'TR13' against the manufacturer's official documentation to confirm reel quantity and tape-and-reel packaging specifications. Ensure the procurement order matches the exact part number RFFC2071ATR13 to guarantee compatibility with the intended PCB footprint and thermal requirements. Cross-reference the RoHS status and moisture sensitivity level (MSL 5) prior to assembly planning.

Selection Notes

Select this component when a single-chip solution combining frequency synthesis and mixing is required for broadband applications up to 2.7 GHz. The integrated VCO and PLL reduce external component count compared to discrete solutions. Consider the 125 mA current draw and thermal dissipation capabilities of the QFN-32 package during board layout. This device is suitable for designs requiring precise frequency control with minimal phase noise and high linearity.

Part Context

The RFFC2071A belongs to Qorvo's family of integrated RF transceivers and synthesizers designed for cellular infrastructure. It replaces earlier discrete or semi-integrated architectures by consolidating the LO generation and frequency conversion stages. The device is commonly used in multi-standard base station front-ends where size, power efficiency, and spectral purity are critical design constraints.

Replacement Considerations

The RFFC2071A is the enhanced version of the RFFC2071. Verify pinout and register compatibility if substituting between these variants. No other direct public substitutes are confirmed in the provided documentation.

FAQ

What is the minimum frequency step size of the integrated synthesizer?

The fractional-N synthesizer utilizes advanced sigma-delta modulation to provide an ultra-fine typical step size of 1.5 Hz.

Can the device operate without using the integrated mixers?

Yes, the RFFC2071A can be configured to bypass the integrated mixers and function solely as a signal source.

How is the device programmed and controlled?

Device programming is executed via a simple 3-wire or 4-wire serial interface, allowing control of multiple devices over a common bus.
