HMC882ALP5ETR

Overview

The HMC882ALP5ETR is a monolithic microwave integrated circuit (MMIC) low-pass filter manufactured by Analog Devices Inc. It features a user-selectable cutoff frequency adjustable from 3.95 GHz to 6.9 GHz via a single analog tuning voltage ranging from 0 V to 14 V applied to the VFCTL pin. The device provides a typical insertion loss of 3 dB and a return loss of 13 dB, with stopband attenuation exceeding 20 dB at 1.28 times the cutoff frequency. It operates within an ambient temperature range of -40°C to +85°C and is housed in a RoHS-compliant, 32-lead, 5 mm × 5 mm LFCSP package.

Feature Summary

• Single-chip tunable low-pass filter replacing mechanically tuned designs
• Wideband rejection capability exceeding 35 dB above 30 GHz
• Low residual phase noise of -165 dBc/Hz at 1 MHz offset
• Amplitude settling time of 200 ns for dynamic adjustment

Applications

• Testing and measurement equipment
• Military radar and electronic warfare/electronic countermeasures (ECMs)
• Satellite communication and space systems
• Industrial and medical equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct channels. Confirm the specific ordering suffix matches the required reel quantity and packaging format. Ensure the procurement documentation aligns with the RoHS compliance status indicated in the official datasheet. Cross-reference the manufacturer part number against current availability lists to confirm active production status before finalizing orders.

Selection Notes

Select this component when a dynamically adjustable cutoff frequency between 3.95 GHz and 6.9 GHz is required. Ensure the control circuit can supply a stable analog voltage between 0 V and 14 V to the VFCTL pin. Verify that the system accommodates the 32-lead LFCSP package dimensions and thermal requirements. Consider the 200 ns amplitude settling time for applications requiring rapid frequency switching.

Part Context

The HMC882A series represents a family of MMIC low-pass filters designed for high-frequency applications. The HMC882ALP5ETR variant specifically denotes the tape-and-reel packaging option for automated assembly. It serves as a compact alternative to physically large switched filter banks and cavity-tuned filters, offering microphonics immunity due to its monolithic construction.
