SERIES PSA
GENERAL INFORMATION
The PSA Series attenuators are “pill” devices designed for installation in
stripline circuits. The element is a thin film laser trimmed chip, en-
capsulated in an epoxy. The resilient spring configuration provides
positive ground plane contact, regardless of variations in ground plane
spacing tolerances. The PSA Series attenuators are ideal for high-rel
applications.

Notes:
% OF RATED POWER
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, 200 watts peak.
4. Standard values 1, 2, 3, 4, 5, 6, 10, 20 dB.
Non-std values available as special order.
