LOW POWER
ATTENUATORS, CHIP SERIES PCA, PCAA
DC-18 GHz
FEATURES
• Laser Trimmed
• Temperature Stable
GENERAL INFORMATION
The PCA and PCAA Series consists of a laser trimmed distributed thin film
element on an alumina ceramic substrate with solderable terminals. Two
sizes are available. The PCAsize operates to 12.4 GHz and the PCAAsize
operates to 18.0 GHz. Both sizes are available with leads and wrap around
conductors for ease of installation. The PCAF and PCAAF options are
designed for “flip-chip” application in lower frequency circuits.
GENERAL SPECIFICATIONS
Impedance: 50 Ohms
Operating Temperature: –55°C to +150°C
Attenuation Stability: 0.0001 dB/dB/°C

Notes
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.
