Analog Devices Inc. 110431-HMC565LC5

Overview

HMC565LC5 from Analog Devices is a GaAs pHEMT MMIC low-noise amplifier operating from 6 to 20 GHz, delivering 21 dB small-signal gain, 2.5 dB noise figure, and +20 dBm OIP3 with single +3 V supply at 53 mA. It is housed in a RoHS-compliant 5×5 mm ceramic LCC package and used as an LNA in microwave point-to-point radios.

For engineers reviewing the HMC565LC5 datasheet, HMC565LC5 pinout, HMC565LC5 application, or HMC565LC5 equivalent, key selection criteria include broadband 6–20 GHz operation, DC-blocked 50 Ω RF I/Os, self-biased architecture, thermal performance up to +85 °C, and MSL3 reflow compatibility.

Technical Context

The HMC565LC5 employs a monolithic GaAs pHEMT process for high-frequency linearity and low-noise performance across 6–20 GHz. Its self-biased topology eliminates external bias networks, while integrated 50 Ω input/output matching enables direct RF interface without external tuning.

Thermal design relies on the exposed paddle (Pin 16) soldered to ground, with channel-to-paddle thermal resistance of 119.5 °C/W and max operating temperature of +85 °C. Absolute maximum drain voltage is +3.5 Vdc, and ESD rating is HBM Class 1A.

Key Specifications

Pinout & Package

The HMC565LC5 uses a 32-pin ceramic leadless chip carrier (LCC) with 5×5 mm footprint and exposed thermal paddle (Pin 16). Ground pins (3, 5, 20, 22) and N/C pins (1, 2, 6–19, 23–25, 27, 29, 31, 32) must be connected to RF/DC ground. The exposed paddle is electrically and thermally tied to ground.

FAQ

What is the operating frequency range of the HMC565LC5?

The HMC565LC5 operates from 6 to 20 GHz with fully characterized performance across this band. Typical gain remains ≥16 dB, noise figure ≤3.0 dB, and OIP3 ≥+20 dBm throughout. This makes HMC565LC5 suitable for Ku-band, extended C-band, and lower Ka-band systems where wide instantaneous bandwidth is required without retuning.

Does the HMC565LC5 require external bias circuitry?

No, the HMC565LC5 features a self-biased architecture and operates from a single +3 V supply applied to Pins 26, 28, and 30. External bias tees or resistive networks are unnecessary. However, each Vdd pin requires local bypassing with 100 pF and 2.2 µF capacitors per the application circuit to ensure stable RF performance across 6–20 GHz.

How is thermal management handled in the HMC565LC5 package?

The HMC565LC5 uses a 32-terminal ceramic LCC with an exposed thermal paddle (Pin 16) that must be soldered to the PCB ground plane. With a channel-to-paddle thermal resistance of 119.5 °C/W, proper paddle connection enables safe dissipation of up to 0.753 W at +85 °C ambient. Thermal vias under the paddle are strongly recommended to enhance heat transfer to internal ground layers.

Is the HMC565LC5 compatible with lead-free reflow processes?

Yes, the HMC565LC5 is RoHS-compliant and rated MSL3 with a maximum peak reflow temperature of 260 °C. Its gold-over-nickel lead finish and alumina ceramic body support standard lead-free soldering profiles. Board design must ensure uniform heating and avoid thermal shock to prevent microcracking in the monolithic GaAs die.

Can the HMC565LC5 be used in space-grade applications?

The HMC565LC5 is not radiation-hardened or qualified to ESCC or MIL-PRF-19500 standards. While it operates over −40 to +85 °C and has HBM Class 1A ESD protection, its qualification is commercial/military-temp only. For space applications, users must perform full radiation testing and derating analysis; Analog Devices does not specify total ionizing dose (TID) or single-event effects (SEE) data for HMC565LC5.
