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 terminals—“F” option

• Standard values 1, 2, 3, 4, 5, 6, 10, 20 dB

• Non-std. values available as special order

Operating Temperature –55°C to +150°C

Attenuation Stability 0.0001 dB/dB/°C

50 Ohms

ORDERING INFORMATION

The attenuators listed are available in 1 dB increments from 1

through 20 dB. When ordering, to specify the correct part num-

ber for the desired attenuation value, select any of the series

listed and add the attenuation value desired to the basic series

designation.

NOTES

Basic Option(s)

Option(s)

1. Performance of other dB values vary dependent on attenuation.

Contact factory for specifications for fractional dB values.

2. Performance is based on device mounted in matched 50 ohm line.

3. Rated power 1.5 watts input PCA, 100 mw PCAA.

EXAMPLES: PCAW-T3

PCAAF-G3

4. Tinnning with SN96 “Lead Free” high temperature solder will maintain RoHS

compliance.
