HMC892LP5E

Overview

The HMC892LP5E is a monolithic microwave integrated circuit (MMIC) bandpass filter designed for surface-mount technology. It features a user-selectable passband frequency tunable between 4 GHz and 7.7 GHz via an analog control voltage ranging from 0 V to 14 V. The device exhibits a typical 3 dB bandwidth of approximately 9% and a 20 dB bandwidth of approximately 23%. Key electrical specifications include an insertion loss of 8 dB, a return loss of 9 dB, and a maximum input power for linear operation of 10 dBm. The component operates within a temperature range of -40 °C to +85 °C and utilizes a 32-lead 5x5 mm SMT package.

Procurement Notes

Verify the obsolete status of this component before initiating any procurement activities. Confirm availability through authorized distributors or Analog Devices directly. Ensure that the specific lot number and marking requirements align with current manufacturing standards. Validate that the supplier provides appropriate handling precautions due to electrostatic sensitivity.

Selection Notes

Select this component when a dynamically adjustable solution is required to replace physically large switched filter banks or cavity-tuned filters. Ensure the driver circuit supports the necessary source/sink currents of ±1 mA for both frequency and bandwidth control voltages. Verify that the application environment remains within the specified operating temperature range of -40 °C to +85 °C.

Part Context

The HMC892LP5E belongs to the Hittite Microwave Corporation product line, which was acquired by Analog Devices Inc. It is part of a series of tunable MMIC bandpass filters designed for advanced communications applications. The device serves as a compact alternative to traditional mechanical tuning mechanisms, offering significant size reduction while maintaining performance in RF signal processing chains.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the datasheet explicitly marks the HMC892LP5E as OBSOLETE, direct replacements may require design modifications or selection of newer generation tunable filters from the manufacturer's portfolio.

FAQ

How is the center frequency controlled?

The center frequency is varied between 4 GHz and 7.7 GHz by applying an analog tune voltage (Vfctl) between 0 V and 14 V.

What is the residual phase noise performance?

The residual phase noise at a 1 MHz offset is typically -165 dBc/Hz.

What are the control voltage requirements?

Both the frequency control voltage (Vfctl) and bandwidth control voltage (Vbwctl) operate within a range of 0 V to 14 V, requiring a source/sink current of ±1 mA.
