Analog Devices Inc. HMC554ALC3BTR-R5

Overview

HMC554ALC3BTR-R5 from Analog Devices is a GaAs MMIC double-balanced mixer operating from 10 GHz to 20 GHz, supporting both upconversion and downconversion with 8.5 dB typical conversion loss, 37 dB LO-to-RF isolation, and +20 dBm input IP3. It serves as a core RF front-end component in microwave radios and electronic warfare systems requiring high-frequency signal translation without external matching.

For engineers reviewing the HMC554ALC3BTR-R5 datasheet, HMC554ALC3BTR-R5 pinout, HMC554ALC3BTR-R5 application, or HMC554ALC3BTR-R5 equivalent, this page delivers verified RF performance data, thermal and ESD ratings, LCC package layout, and validated alternatives for Ka-band transceiver design, test instrumentation, and military EW subsystems.

Technical Context

The HMC554ALC3BTR-R5 employs a passive double-balanced topology fabricated in GaAs MESFET process, eliminating bias circuitry and external matching components. Its optimized balun structures deliver simultaneous high LO-to-RF (37 dB typ), LO-to-IF (41 dB typ), and RF-to-IF (41 dB typ) isolation across the full 10–20 GHz band.

It supports DC–6 GHz IF bandwidth with dc-coupled IF port and ac-coupled 50 Ω-matched RF/LO ports. Operation requires no external DC blocking or biasing-only proper RF grounding of all GND pins and the exposed pad per JEDEC E-12-41 footprint.

FAQ

What is the maximum RF input power rating for the HMC554ALC3BTR-R5?

The HMC554ALC3BTR-R5 has an absolute maximum RF input power rating of +25 dBm, as specified in the Absolute Maximum Ratings table. Exceeding this level risks permanent damage to the GaAs die. For reliable operation, RF input should remain ≤+20 dBm under continuous conditions, especially at elevated temperatures, to maintain P1dB margin and avoid compression-induced distortion in the HMC554ALC3BTR-R5.

Does the HMC554ALC3BTR-R5 require external DC blocking capacitors on the RF or LO ports?

No, the HMC554ALC3BTR-R5 does not require external DC blocking capacitors on the RF or LO ports because both are internally ac-coupled and 50 Ω matched across 10–20 GHz. The IF port is dc-coupled; if dc operation is not needed, an external series capacitor must be added to block dc while passing the desired IF band-this requirement is specific to the IF path, not RF or LO, in the HMC554ALC3BTR-R5.

Can the HMC554ALC3BTR-R5 operate with IF frequencies down to DC?

Yes, the HMC554ALC3BTR-R5 supports true DC-coupled IF operation, enabling baseband and low-IF architectures. However, the IF pin must not source or sink more than ±3 mA of current, as exceeding this limit may cause die malfunction or failure. This dc capability is intrinsic to the HMC554ALC3BTR-R5 design and confirmed in the Pin Function Descriptions section of its datasheet.

What is the recommended PCB grounding strategy for the HMC554ALC3BTR-R5?

The HMC554ALC3BTR-R5 requires low-inductance RF grounding of all six GND pins (1, 3, 4, 6, 7, 9) and the exposed pad (EPAD) to a solid, unbroken ground plane. Thermal vias under the EPAD (≥6×0.3 mm diameter) are mandatory for thermal management. NIC pins (10–12) may be grounded but are optional. This grounding scheme ensures optimal balun balance, isolation, and thermal performance in the HMC554ALC3BTR-R5.

Is the HMC554ALC3BTR-R5 RoHS compliant and MSL rated?

Yes, the HMC554ALC3BTR-R5 is RoHS compliant and qualified per JEDEC J-STD-020 moisture sensitivity level (MSL) 3, with a floor life of 168 hours at ≤30°C/60% RH. It is compatible with standard Pb-free reflow profiles peaking at 260°C. These compliance attributes are explicitly stated in the Features and Ordering Guide sections of the official HMC554ALC3BTR-R5 datasheet.
