HMC1162LP5ETR

Overview

The HMC1162LP5ETR is a GaAs MMIC Voltage Controlled Oscillator (VCO) from Analog Devices Inc., designed for high-frequency RF applications. It operates with a fundamental frequency range of 4.625 GHz to 5.050 GHz and provides a half-frequency output ranging from 9.25 GHz to 10.10 GHz. The device requires a single 5 V supply voltage and draws a maximum current of 250 mA. It features a tuning sensitivity of 2 MHz/V with a control voltage range of 2 V to 13 V. Output power levels are specified at 3.5 ± 4.5 dBm for the fundamental frequency and 11 ± 4 dBm for the divided output. Typical phase noise is -86 dBc/Hz, and second harmonic suppression is typically 20 dBc. The component is housed in a compact 32-VFQFN package with exposed pad, measuring 5.00 mm x 5.00 mm.

Feature Summary

• Integrates a GaAs MMIC VCO core with an on-chip frequency divider to provide dual-band output capability.
• Delivers stable RF performance across a wide temperature range suitable for demanding environments.
• Utilizes a compact surface-mount QFN package to minimize PCB footprint and facilitate automated assembly.

Applications

• Point-to-point microwave radio links
• Local oscillator sources for upconversion and downconversion mixers
• Test and measurement instrumentation equipment
• Satellite communication ground stations

Procurement Notes

Verify that the ordering suffix matches the required tape and reel configuration for automated pick-and-place manufacturing processes. Confirm that the design-in review includes adequate thermal management strategies, as the exposed pad requires soldering to a copper pour for proper heat dissipation. Ensure that the supply voltage regulation meets the strict tolerance requirements to maintain frequency stability and prevent excessive current draw during operation.

Selection Notes

Select this component when a single-device solution is required to generate both fundamental and divided frequencies without external dividers. Consider the specific phase noise requirements at offset frequencies relative to the carrier. Evaluate the available tuning voltage range against the capabilities of the loop filter or DAC in the PLL system. Compare the output power levels against the input sensitivity of subsequent stages to determine if additional amplification is necessary.

Part Context

This part belongs to the HMC116x series of VCOs with integrated output dividers, manufactured by Analog Devices Inc. The series offers various frequency bands tailored for different RF applications. The LP5E designation indicates the specific leadless package type used for surface mount technology. This family is engineered to provide high spectral purity and low phase noise characteristics essential for modern wireless communication systems.

Replacement Considerations

Direct pin-compatible replacements within the same series include HMC1161LP5ETR, HMC1163LP5ETR, and HMC1164LP5ETR, which offer different frequency ranges but similar packaging and electrical interface characteristics. Cross-series substitution requires careful verification of frequency coverage, output power levels, and phase noise specifications to ensure system compatibility.
