LPF-B375+
50Ω
DC to 375 MHz
The Big Deal
• Good passband Insertion loss, 1 dB typical
• High rejection, 50 dB typical from 450-3000 MHz
• Fast roll-off
CASE STYLE: HZ1198
• Good VSWR, 1.3:1 typical in passband
• Miniature shielded package
Product Overview
The LPF-B375+ is a lowpass filter in a shielded package (size of 0.472" x 0.826" x .22") fabricated using SMT tech-
nology. Covering DC-375 MHz band width, these units offer good matching within the passband and high rejection.
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
Low frequency and good passband
Insertion loss, 1 dB typical
Low insertion loss will be used in designs optimized for high performance applications.
Fast roll-off
Fast roll-off, this will attenuate frequencies closer to the passband with good rejection value of 72 dB.
This enables the filters to attenuate spurious signals and reject harmonics for broadband frequency.
Good ultimate rejection
Good VSWR, 1.3:1 typical in
passband
The model has very good return loss for this bandwidth and provides good interface when used with
others devices.
