Product Overview
SXLP-400+ is a lowpass filter fabricated using SMT technology. Covering up to 400 MHz, these units offer low inser-
tion loss, good matching within the passband and high rejection This model also offers flat group delay characteristics.
This unit uses a miniature high Q capacitors and wire welded inductors for high reliability. In addition it has repeatable
performance across production lots and consistent performance across temperature.
Key Features
Feature
Advantages
This enables the filter to attenuate spurious signals and reject harmonics over a broad band of fre-
quency.
Wide rejection up to 6000 MHz
Good VSWR, 1.36:1 typical over
Passband
The model has very good return loss which provides good matching when used with other devices.
Sharp shape factor helps in adjacent channel rejection and hence icreased selectivity.
The small surface mount package enables the SXLP-400+ to be used in compact designs.
Sharp roll off shape factor, 1.2
Small size, 0.44" x 0.74" x 0.27"
