Device Overview

General Description

The MFBT-00002PSM is a surface mount MMIC tunable filter for adaptive filtering applications. The MFBT-00002PSM offers separate low pass and high pass tuning capability, allowing users to create bandpass filters with variable center frequencies and % bandwidths. Performance features include low return loss in both the passband and stopband and low insertion loss, high stopband rejection, and high IP3 relative to other tunable filters. The MFBT-00002PSM is available as a 4x4mm plastic QFN, replacing much larger switched filter banks.

Specifications

Absolute Maximum Ratings

The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. All limits are individual and should not be met in parallel, doing so will degrade the lifetime of the device. If these limits are exceeded, the device may be inoperable or have a reduced lifetime.

The Recommended Operating Conditions indicate the limits, inside which the device should be operated, to guarantee the performance given in Electrical Specifications Operating outside these limits may not necessarily cause damage to the device, but the performance may degrade outside the limits of the electrical specifications. For limits, above which damage may occur, see Absolute Maximum Ratings.
