HMC899LP4ETR

Overview

The HMC899LP4ETR is a monolithic microwave integrated circuit (MMIC) bandpass filter manufactured by Analog Devices Inc. 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 approximately 35%. Key electrical specifications include a maximum insertion loss of 7 dB, a return loss of 10 dB, and an input IP3 of 25 dBm. The component operates within a temperature range of -55 °C to +85 °C and utilizes a die-level package with gold bond pads.

Feature Summary

• Provides fast tuning response with phase settling to within 10 degrees in less than 100 nanoseconds.
• Delivers excellent wideband rejection capabilities for interference mitigation.
• Functions as a single-chip replacement for mechanically tuned designs, offering reduced physical size.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging and handling requirements. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Confirm compliance with relevant environmental standards such as RoHS before finalizing acquisition.

Selection Notes

Select this component when a dynamically adjustable filter solution is required to replace bulky switched filter banks or cavity-tuned filters. Consider the 19 GHz to 38 GHz tuning range and the requirement for an external low-noise driver circuit to achieve optimal residual phase noise performance. Evaluate the need for microphonics resistance inherent in the monolithic design for the target application environment.

Part Context

The HMC899LP4ETR belongs to the HMC899 series of tunable MMIC bandpass filters produced by Analog Devices Inc., formerly Hittite Microwave Corporation. This series is designed for advanced communications applications requiring small form factors and high performance in the millimeter-wave spectrum.

Replacement Considerations
