HMC890ALP5ETR

Overview

The HMC890ALP5ETR 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 center frequency controlled by an analog voltage between 0 V and 14 V applied to the VFCTL pin. The device provides approximately 10% bandwidth at the 3 dB level and 30% at the ≥20 dB level. Key electrical specifications include a maximum insertion loss of 12 dB, return loss of 10 dB, input third-order intercept point (IP3) of 35 dBm, and amplitude settling time of 200 ns. It operates within a temperature range of -40°C to +85°C and is housed in a 32-lead, 5 mm × 5 mm LFCSP package.

Feature Summary

• Monolithic design eliminates microphonics associated with mechanically tuned filters
• Dynamically adjustable center frequency via single analog control voltage
• Excellent wideband rejection characteristics for interference suppression
• Single chip replacement for physically large switched filter banks

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm the reel packaging configuration. Ensure that the component meets RoHS compliance requirements as stated in the manufacturer's ordering guide. Confirm that the supply chain source provides valid traceability for the MMIC batch. Cross-reference the part number with the latest datasheet revision to ensure all technical parameters remain current before finalizing procurement orders.

Selection Notes

Select this component when a compact, dynamically tunable RF filter is required to replace bulky cavity or switched bank designs. The device supports independent or tied control voltages for center frequency and bandwidth adjustment. Verify that the application environment stays within the specified -40°C to +85°C operating range. Ensure the system can provide stable 0 V to 14 V control signals without exceeding absolute maximum ratings.

Part Context

This part belongs to the HMC890 series of tunable band-pass filters manufactured by Analog Devices. It serves as a direct functional upgrade to mechanical tuning solutions in RF front-end architectures. The device integrates filtering capabilities into a small surface-mount package, enabling significant size reduction in high-frequency signal processing chains compared to traditional discrete filter assemblies.
