HMC899LP4E

Overview

The HMC899LP4E is a monolithic microwave integrated circuit (MMIC) bandpass filter designed for millimeter-wave applications. It features a user-selectable passband frequency tunable between 19 GHz and 38 GHz via an analog control voltage ranging from 0 V to 14 V. The device exhibits a typical 3 dB bandwidth of approximately 18% and a 20 dB bandwidth of roughly 35%. Key electrical specifications include a maximum insertion loss of 7 dB, a return loss of 10 dB, and an input third-order intercept point (IP3) of 25 dBm. The component operates within a temperature range of -55 °C to +85 °C and utilizes a compact surface-mount package.

Feature Summary

• Provides fast tuning response with phase settling to within 10° in under 100 ns
• Delivers excellent wideband rejection characteristics suitable for advanced communications
• Functions as a single-chip replacement for mechanically tuned designs and switched filter banks

Applications

• Test & Measurement Equipment
• Military RADAR & EW/ECM Systems
• SATCOM & Space Applications
