ADPA7009CHIP

RF Amplifiers Overview

The ADPA7009CHIP is a gallium arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) monolithic microwave integrated circuit (MMIC) power amplifier. It operates within a frequency range of 20 GHz to 54 GHz. The device provides a typical gain of 19.5 dB and delivers a saturated output power (Psat) of 29 dBm (0.5 W). At the 1 dB compression point (P1dB), the output power is 28.5 dBm across the 24 GHz to 36 GHz band. The input third-order intercept point (IP3) typically reaches 35 dBm in the same frequency range. The amplifier requires a 5 V supply voltage and draws 750 mA of current. Input and output impedances are internally matched to 50 ohms.

RF Amplifiers Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm that the specific package type matches design requirements, as the device utilizes RF pads connected via bond wires. Check for obsolescence status, as availability may be limited. Ensure thermal management solutions align with the 750 mA operating current and 5 V supply conditions specified in the official datasheet.

RF Amplifiers Selection Notes

Select this component when a wideband 20 GHz to 54 GHz coverage is required. The internal 50-ohm matching simplifies circuit design compared to unmatched variants. Consider the 750 mA current draw for power budget calculations. Evaluate the 29 dBm Psat against system link budget requirements. Verify compatibility with multi-chip module (MCM) integration strategies due to the bare die or specialized packaging nature of MMICs.

RF Amplifiers Part Context
