QPA4363ATR7

Video Amps And Modules Overview

The QPA4363ATR7 is a cascadable SiGe HBT MMIC amplifier operating from DC to 4000 MHz. It features a Darlington configuration for high FT and thermal performance, with internally matched 50-ohm impedance. Typical gain is 14.8 dB at 1950 MHz, output IP3 is +29.2 dBm, and noise figure is 3.0 dB. The device operates on a single positive voltage supply (typical VD = +3.2 V) and draws 45 mA. It is housed in a lead-free, RoHS-compliant SOT-363 package.

Video Amps And Modules Feature Summary

• Utilizes a Darlington configuration to provide high transition frequency and excellent thermal stability while minimizing leakage current.
• Features internal cancellation of emitter junction non-linearities to suppress intermodulation products and improve linearity.
• Includes robust ESD protection rated at 1000V Class 1C Human Body Model.
• Internally matched to 50 ohms, requiring only external DC-blocking capacitors and bypass components for operation.
