HMC890ALP5E

Overview

The HMC890ALP5E is a monolithic microwave integrated circuit (MMIC) tunable band-pass filter operating from 1.0 GHz to 1.9 GHz. It features a user-selectable pass-band frequency controlled by an analog voltage between 0 V and 14 V applied to the VFCTL pin. The device offers excellent wideband rejection of ≥30 dB, with a typical insertion loss of 12 dB and return loss of 10 dB. Packaged in a 32-lead, 5 mm × 5 mm LFCSP, it serves as a compact single-chip replacement for mechanically tuned designs.

Feature Summary

• User-selectable center frequency via analog tuning voltage
• Excellent wideband rejection performance
• Compact single-chip alternative to mechanical filters

Applications

• Test and measurement equipment
• Military radar and electronic warfare/electronic countermeasures
• Satellite communications and space applications
• Industrial and medical equipment

Procurement Notes

Verify the specific package option required for the application. The standard tape and reel variant is designated HMC890ALP5ETR. Confirm that the evaluation board EV1HMC890ALP5 is requested separately if hardware validation is needed. Ensure all control pins are driven within the specified absolute maximum ratings to prevent damage.

Selection Notes

Select this component when a dynamically adjustable RF filter is required in a small form factor. The device supports independent or tied control voltages for VFCTL and VBWCTL. Verify that the system can provide the necessary 0 V to 14 V tuning range. Consider the thermal management requirements associated with the exposed pad connection for proper grounding.

Part Context

This part belongs to the HMC890 series of tunable active filters manufactured by Analog Devices. It utilizes MMIC technology to replace bulky switched filter banks or cavity-tuned filters. The device is RoHS compliant and designed for high-reliability applications requiring low microphonics and stable performance across temperature variations.
