Product Overview
SXLP-3+ is a 50Ω lowpass filter fabricated using SMT technology. This lowpass filter covers from DC-3 MHz band-
width, these units offer good matching within the passband and high rejection. This units 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 is a low frequency filter and this will also attenuate frequencies closed to the passband with
good rejection value of >20 dB.
Low frequency and fast roll-off
Good VSWR, 1.2:1 typical in pass-
band
The SXLP-3+ has very good return loss for a low frequency bandwidth and provides good interface
when used with other devices.
Small size, 0.44" x 0.74" x 0.27"
The small surface mount package enables the SXLP-3+ to be used in compact designs.
