Fighter nose radars are still in the kilowatt range. Those systems are also rather light (~700lbs all totaled, not counting coolant). There may be pylon-mounted systems that get to the upper end of that (>100kW). High power airborne radars are typically carried by larger, purpose-built platforms such as the E-2C, E-3, and E-8.
