HMC1000LP5ETR

Overview

The HMC1000LP5ETR is a monolithic microwave integrated circuit (MMIC) band reject filter operating from 3.6 to 12.2 GHz. It features user-selectable rejection frequency via two control voltages, Vt1 and Vt2, ranging from 0 to 14 VDC with ±1 mA current capability. The device offers four tuning modes for full-band frequency selection, low/high-band narrowing, or bandwidth adjustment. Key electrical parameters include -162 dBc/Hz residual phase noise at 100 kHz offset, less than 200 ns phase settling time, and a rejection band center drift rate of -0.3 MHz/°C. It operates within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Supports four distinct tuning modes enabling full-band frequency selection, narrow-band low/high-frequency tuning, and independent rejection bandwidth adjustment.
• Features fast phase settling performance with typical tuning voltage ramp times included in the total response duration.
• Provides high linearity with input IP3 exceeding 40 dBm in the passband and rejection band under specified power conditions.

Applications

• Frequency agile radar systems requiring tunable interference suppression
• Software-defined radio architectures needing dynamic notch filtering
• Electronic warfare applications involving selective signal rejection

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to obsolete status. Confirm package marking matches H1000 lot identifiers. Ensure handling precautions are followed as the device is electrostatic sensitive. Validate that the specific EOL notification applies to the intended production timeline.

Selection Notes

Select this component when wideband tunable rejection between 3.6 and 12.2 GHz is required. Evaluate thermal resistance of 40°C/W for junction temperature management. Consider the need for low-noise driver circuits to optimize residual phase noise performance across the tuning range.

Part Context

This MMIC belongs to the Hittite Microwave Corporation portfolio, now part of Analog Devices Inc. It represents a surface-mount technology solution designed for integration into compact RF front-ends. The device utilizes a leadframe construction with copper alloy leads and matte tin finish.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is marked obsolete, engineering change orders should reference official discontinuance notifications for potential qualified replacements.

FAQ

What are the absolute maximum ratings for the frequency control voltage?

The absolute maximum rating for the frequency control voltage (Vfctl) is -0.5 V to +15 V.

How does the rejection band center frequency drift with temperature?

The rejection band center frequency exhibits a drift rate of -0.3 MHz per degree Celsius over the operating temperature range.

What is the typical tuning speed for phase settling?

The tuning speed includes phase settling to within 10 degrees in less than 200 nanoseconds, which accounts for a typical 40 nanosecond tuning voltage ramp from the driver.
