ADPA7005CHIP

RF Amplifiers Overview

The ADPA7005CHIP is a GaAs pHEMT monolithic microwave integrated circuit (MMIC) power amplifier designed for operation within the 20 GHz to 44 GHz frequency range. It delivers an output power exceeding 1 W (32 dBm) at the 1 dB compression point. The device operates on a single positive supply voltage of 5 V with a typical current consumption of 1.4 A. Key electrical characteristics include a small-signal gain of approximately 15.5 dB and a noise figure of 11 dB. The component features an input return loss of 18 dB and dissipates up to 12.33 W of power. It is manufactured using Gallium Arsenide technology and is rated for operation between -40°C and +85°C.

RF Amplifiers Procurement Notes

Verify the specific ordering suffix and revision level against the official Analog Devices datasheet to ensure compatibility with system requirements. Confirm that the procurement channel provides genuine components with traceable documentation. Check for any specific handling instructions related to the bare die format, as electrostatic discharge protection is critical during storage and assembly processes.

RF Amplifiers Selection Notes

Select this component when designing circuits requiring high output power above 1 W in the Ka-band or higher frequencies. Ensure the PCB layout supports the thermal dissipation needs associated with 12.33 W power dissipation. Verify that the biasing network can provide stable 5 V supply and handle the 1.4 A current draw without significant voltage drop or noise injection into the RF path.

RF Amplifiers Part Context

This part belongs to the ADPA7005 series of MMIC power amplifiers from Analog Devices. It is available in various configurations, including the ADPA7005AEHZ-R7 in an LCC-HS-18 package and evaluation kits like the ADPA7005C-KIT. The CHIP variant specifically refers to the bare die form factor, intended for custom packaging or integration into larger subsystems where space constraints are minimal.

RF Amplifiers Replacement Considerations

Direct replacements may include other GaAs pHEMT MMICs from Analog Devices within the same frequency band offering similar power levels. Cross-reference specifications such as P1dB, gain flatness, and supply voltage requirements carefully. Consult the manufacturer's documentation for updated pin-compatible alternatives or upgraded generations within the ADPA700x family.
