102 programmable attenuators p-at series features 1. used for frequencies from dc to 26.5ghz (max.) input/output couplings utilizes hirose? he* connector, which is combination of the internal attenuation elements, provides the required attenuation characteristic. 2. self-disconnecting the drive current will automatically switch off after setting the attenuation. 3. automatic return in the event of sudden shock the attenuation will quickly return to the pre-set level. applications wide variety of measuring instruments and other devices requiring control of high frequency transmission lines. * he connector will mate with k type connectors * k connector is a trademark of anritsu co. p-at - 6 ( 8 - 70 ) a 1 2 3 4 5 product specifications ratings frequency range dc~8ghz(p-at-6,ap-at-7) dc~26.5ghz(p-at-8) operating temperate range operating relative humidity -10 ? to +75 ?(no freezing) 95% max. characteristic requirements 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 55 hz, overall amplitude of 1.5 mm for 2 hours in each of 3 directions acceleration of 98 m/s 2 , sine half-wave waveform, 3 cycles in each of the 3 axis the test method conforms to mil-std-202. materials and finishes ordering information component body aluminum conductive alumite coupling connector body stainless steel passivated female contact beryllium copper gold plating material finish series name suffix maximum frequency (ghz) maximum attenuation (db) revised 1 2 3 4 5
