SERIES PCA, PCAA ATTENUATORS, CHIP Low Power DC-18 GHz FEATURES Laser Trimmed Temperature Stable GENERAL INFORMATION The PCA and PCAA Series consists of a laser trimmed distrib- uted thin film element on an alumina ceramic substrate with solderable terminals. Two sizes are available. The PCA size operates to 12.4 GHz and the PCAA size operates to 18.0 GHz. Both sizes are available with leads and wrap around conduc- tors for ease of installation. The PCAF and PCAAF options are designed for flip-chip application in lower frequency circuits. PCA & PCAA SERIES DATA Substrate: 96% Alumina Solderable Terminals: Electroplated Silver over Nickel Resistive Element: Proprietary Thin Film Wrap around Ground Terminal available, W option Wrap around-all terminalsF option Standard values 1, 2, 3, 4, 5, 6, 10, 20 dB Non-std. values available as special order GENERAL SPECIFICATIONS Impedance 50 Ohms ORDERING INFORMATION Operating Temperature 55C to +150C The attenuators listed are available in 1 dB increments from 1 through 20 dB. When ordering, to specify the correct part num- Attenuation Stability 0.0001 dB/dB/C ber for the desired attenuation value, select any of the series listed and add the attenuation value desired to the basic series designation.
