81 high power fixed attenuators (heat sink mounting type) at-1200 and at-1300 series features 1.small size and economical beryllia is used for the material of the resistance element to enable the attenuation to be of small size and low cost. 2.high power capacity mounting these attenuators to a heat sink permits the at-1200 series to be used at up to 30 w and the at- 1300 series to be used at up to 50 w. 3.high reliability these attenuators show stable characteristics for environments of varying temperature, humidity, and gases. at-1210-h ? j(40) at-1320-h ? j(40) product specifications ratings frequency range (note) characteristic impedance maximum input power (note) dc to 2.0 ghz 50 ohms 30 to 50 w operating temperature range operating relative humidity C10? to + 65? 95% max. note: the frequency range and the maximum input power will differ depending on the products. item standard conditions 1.vibration 2.shock 3.temperature cycle no electrical discontinuity of 1 s or more no damage, cracks, or parts dislocation no damage, cracks, or parts dislocation frequency of 10 to 2000 hz, overall amplitude of 1.52 mm, acceleration of 98 m/s 2 for 2 hours in each of 3 directions acceleration of 490 m/s 2 , sine half-wave waveform, 3 cycles in each of the 3 axis temperature: -55 ? +15 ? to +35 ? +85 ? +15 ? to +35 ? time: 30 15 max. 30 15 max.
