ADL5205ACPZ-R7

RF Amplifiers Overview

The ADL5205ACPZ-R7 is a digitally controlled, wide bandwidth variable gain dual amplifier (DGA) manufactured by Analog Devices Inc. It operates within a frequency range of 0 Hz to 1.7 GHz and supports supply voltages of 3.3 V or 5 V with a typical current consumption of 175 mA. The device provides a gain range from -9 dB to +26 dB with a 1 dB step size and ±0.2 dB accuracy at 200 MHz. Key electrical parameters include a noise figure of 8.2 dB, a P1dB compression point of 17.7 dBm, and an OIP3 of 36 dBm. It features a 100 ohm differential output impedance and is housed in a 40-lead LFCSP package.

RF Amplifiers Feature Summary

• Digitally controlled variable gain amplification with precise step control
• Dual independent amplifier channels for signal processing flexibility
• Low output impedance design suitable for direct driver applications

RF Amplifiers Applications

• Programmable RF driver stages
• Variable gain amplifier circuits in wireless infrastructure
• Test and measurement equipment requiring adjustable signal levels

RF Amplifiers Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD precautions are observed during handling due to moisture sensitivity classification. Cross-reference the full part number with authorized distributors to confirm current availability and lead times.

RF Amplifiers Selection Notes

Select this component when dual-channel programmable gain is required up to 1.7 GHz. The SiGe technology offers high linearity and low noise characteristics. Consider the 40-lead LFCSP package constraints for PCB layout. Evaluate power dissipation limits against thermal management capabilities in the final enclosure design.

RF Amplifiers Part Context

This part belongs to the ADL5205 series of digitally controlled amplifiers. It is distinct from the ADP5050/ADP5052 PMIC series also listed in search results. The ADL5205-EVALZ development board is available for testing this specific amplifier family. It serves as a core active component in RF front-end designs rather than a passive or power management device.
