TAT7430B

RF Amplifiers Overview

The TAT7430B is a low-cost RF amplifier designed for applications from DC to 1200 MHz. It features a typical gain of 22 dB in an application circuit and operates with flexible biasing between 5 V and 8 V, drawing a typical current of 190 mA at 8 V. The device offers a low noise figure of less than 2.2 dB up to 1000 MHz. Distortion performance includes a typical output third-order intercept point (OIP3) of +41 dBm, OIP2 of +65 dBm, and P1dB of +22 dBm. CSO and CTB are typically -61 dBc and -81 dBc respectively under specified input conditions.

RF Amplifiers Procurement Notes

Verify the specific package variant and manufacturing origin against the latest Qorvo datasheet before procurement. Confirm that the component meets RoHS compliance requirements if mandated by your project specifications. Ensure that the supply chain source provides valid traceability documentation. Check for any recent Product Change Notifications or End-of-Life notices that may affect long-term availability. Validate that the received units match the exact part number designation without unauthorized suffixes.

RF Amplifiers Selection Notes

Select this component when a wide bandwidth covering DC to 1200 MHz is required alongside low noise characteristics. The flexible 5 V to 8 V biasing range allows for integration into various power supply architectures. Consider the SOT-89 package for space-constrained designs requiring single-ended or push-pull configurations. Evaluate the distortion metrics, such as CSO and CTB, against system linearity requirements for CATV or optical receiver front ends.
