HMC894LP5ETR

Overview

The HMC894LP5ETR is a monolithic microwave integrated circuit (MMIC) tunable bandpass filter manufactured by Analog Devices Inc. It features a user-selectable passband frequency with a center frequency range of 5.9 to 11.2 GHz, controlled by an analog voltage between 0 and 14V. The device offers a typical 3 dB bandwidth of approximately 6% and a 20 dB bandwidth of 16.5%. Key electrical specifications include an insertion loss of 9 dB, return loss of 7.5 dB, and maximum input power for linear operation of 10 dBm. It operates within a temperature range of -40°C to +85°C and utilizes a 32-lead 5x5 mm surface mount package.

Feature Summary

• Provides fast tuning response with a full band switching time of 200 ns
• Delivers excellent wideband rejection exceeding 30 dB at the re-entry frequency
• Functions as a single-chip replacement for mechanically tuned filter designs

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm lot numbers against manufacturer records. Ensure handling precautions are followed given electrostatic sensitivity. Validate that the specific suffix matches required packaging standards. Check for compliance with current environmental regulations.

Selection Notes

Evaluate control voltage requirements against available driver circuits. Consider thermal management capabilities within the specified operating temperature range. Assess impedance matching needs for RF input and output ports. Verify bandwidth control voltage compatibility for desired filter characteristics. Review absolute maximum ratings to prevent device damage during operation.

Part Context
