LPF-B50+

50Ω

DC to 50 MHz

The Big Deal

• Good passband Insertion loss, 0.8 dB typical

• High rejection, 50 dB from 70-2000 MHz

• Fast roll-off

CASE STYLE: HZ1198

• Miniature shielded package

Product Overview

The LPF-B50+ is a lowpass ﬁlter in a shielded package (size of 0.472" x 0.826" x .22") fabricated using SMT technol-

ogy. Covering DC-50 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, 0.8 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
