High Power Resistive Products Attenuators AVX introduces its line of High Power Attenuator Products. All products are designed and manufactured at our ISO 9001 Facilities. ELECTRICAL SPECIFICATIONS Attenuation: 1 dB through 30 dB Frequency Range: DC to 3 GHz Input Power: up to 150 Watts Operating Temperature Range: -55C through +150C MECHANICAL SPECIFICATIONS Package: Leaded and Flange Mounted Substrate Material: Aluminum Nitride Process: 100% Thin Film Processed Resistive Material: Tantalum Nitride Terminals: 100% Ag Cover: Alumina Mounting Flange: 100% Cu, Ni or Ag Plated RoHS Compliant HOW TO ORDER RP2 3740 A AVX Series RP1 RP2 Case Size 3740 0975 Type A = Attenuator 01DB F P BK Nominal Attenuation (dB) See chart Tolerance F = 1% Plating P = Palladium Packaging BK = Bulk Contact factory for custom ratings and sizes. Attenuator Power Handling vs. Mounting Surface Temperature 350 Notes: 1. Plot refers to incident continuous power of "P" Watts 2. Mounting surface is assumed an isotherm at TM C 3. Actual testing done at P = 100 Watts, TM = 100 C 4. Plot based on 1-dimensional heat transfer formula: T = TM + PR, where T = area-average resistive film temperature, held to 150 C, max. R = thermal resistance, mounting surface to resistive film 0.5 C/W for 30- and 20- dB devices (other values will run cooler and therefore handle more power - consult factory) 300 Power Handling (Watts) 250 200 150 100 50 0 0 25 50 75 100 125 150 Mounting Surface Temperature (C) * Test Condition: With mounting surface temperature = 75C, max. (see plot above). Actual test conditions are as follows: Flange attached to a large copper carrier whose surface, directly under the flange center, is held at 100C; power applied = 100 Watts. ** Attenuation vs. frequency as a function of temperature, -55C to +125C 2 High Power Resistive Products Attenuators FLANGE MOUNT ATTENUATORS - RP1 SERIES GENERAL SPECIFICATIONS Frequency Range: DC to 3 GHz Input Power*: 150 Watts Operating Temp Range: -55 to +150C Attenuation Stability**: 0.0001 dB/dB/C, Max.
