((full)) - Apak-290

The input stage includes a limiter circuit that survives 200W peak pulses for 1µs—a critical feature for radar systems operating near high-power transmitters.

Why engineers are choosing this integrated solution for mission-critical phased array and communication systems. Introduction In the world of high-frequency electronics, component selection is often a compromise between power handling, noise figure, and physical footprint. Enter the APAK-290 —an integrated RF front-end assembly that is quietly gaining traction among defense contractors and satellite communication engineers. apak-290

| Parameter | Typical Value | | :--- | :--- | | Frequency Range | 2.7 GHz – 3.1 GHz (S-Band) | | Output Power (P1dB) | +43 dBm (20 Watts) | | Gain | 35 dB typical | | Noise Figure | ≤ 1.8 dB | | Switching Speed | < 500 ns | | Supply Voltage | +28 V / +5 V | | Interface | SMA-Female or Blind-mate | 1. Thermal Management Traditional discrete amplifiers struggle with heat dissipation at 20W+. The APAK-290 uses a direct copper-molybdenum flange, allowing conduction cooling directly to a cold plate. This reduces junction temperature by 15°C compared to generic modules. The input stage includes a limiter circuit that
