Product details
Overview
HMC572LC5 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC I/Q downconverter IC designed for RF front-end signal processing in 24–28 GHz systems. It delivers 8 dB small-signal conversion gain, 3.5 dB noise figure, and 18 dB image rejection with DC–3.5 GHz IF bandwidth, operating from +25 °C with 3.5 Vdc supply and 125–165 mA total current draw.
For engineers reviewing the HMC572LC5 datasheet, HMC572LC5 pinout, HMC572LC5 application, or HMC572LC5 equivalent, this device is selected for millimeter-wave receiver architectures requiring integrated image rejection, compact SMT packaging, and high LO-to-RF isolation without external filtering before the mixer stage.
Technical Context
The HMC572LC5 integrates an LNA followed by an image-reject mixer driven by an on-chip active x2 LO multiplier - eliminating need for external image filters and reducing thermal noise contribution at the image frequency. Its architecture enables sideband selection via external 90° hybrid at IF outputs.
It operates as an IRM (Image Reject Mixer) with defined RF (23–28 GHz), LO (9–15.5 GHz), and IF (DC–3.5 GHz) bands, requiring external DC blocking on IF1/IF2 for AC-coupled operation and strict grounding of all GND pins plus exposed paddle per RF design best practices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 23–28 GHz - supports full Ka-band uplink/downlink in satellite comms and radar. |
| Conversion Gain | 8 dB typical - provides net signal amplification before IF processing, reducing cascaded noise impact. |
| Noise Figure | 3.5 dB - enables high sensitivity in low-SNR mmWave receivers. |
| Image Rejection | 18 dB typical - suppresses unwanted sideband without external image filter, simplifying BOM and layout. |
| LO to RF Isolation | 35 dB - minimizes LO leakage into antenna path, critical for transmit/receive coexistence. |
| Input IP3 | +5 dBm - supports moderate interference handling in crowded spectral environments. |
| Supply Current | 125–165 mA @ 3.5 V - defines power budget for bias network and thermal management. |
| Package Size | 5×5 mm SMT - enables dense RF module integration with standardized reflow compatibility (MSL3). |
Pinout & Package
32-lead 5×5 mm leadless SMT package with alumina body, gold-over-nickel plating, and exposed ground paddle requiring soldering to PCB RF ground plane. MSL3 rated; max peak reflow 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7 | VddLO / VddLO2 / VddRF | Separate bias supplies for LO amplifier stages and RF LNA - decoupling required per stage to prevent coupling. |
| 10, 19, 24, 29 | GND | Dedicated RF/DC ground connections - must be tied to ground plane with low-inductance vias. |
| 11 | RF | 50 Ω AC-coupled RF input - matched for direct connection to antenna or filter output. |
| 20, 23 | IF2 / IF1 | DC-coupled quadrature IF outputs - require external DC blocking capacitor unless operating to DC with ≤3 mA current. |
| 30 | LO | 50 Ω AC-coupled LO input - accepts +4 dBm drive; internal x2 multiplier generates required LO harmonic. |
| 2, 4–6, 8, 9, 12–18, 21, 22, 25–28, 31, 32 | N/C | No-connect pins - may be grounded without performance impact but not required. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q downconverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP5E | Wider RF range (17–27 GHz), lower conversion gain (5 dB), no integrated LO multiplier - requires fundamental LO at ~13.5 GHz. | Better suited for lower-frequency Ka-band edge applications where LO source is available at fundamental frequency. | Select when LO source stability or phase noise at fundamental frequency outweighs benefit of internal x2 multiplier. |
| Qorvo QPB1022 | Higher RF range (24–44 GHz), higher conversion gain (10 dB), but no image rejection - requires external image filter and 90° hybrid. | Targeted at ultra-wideband test equipment where flexibility over integration is prioritized. | Choose when system-level calibration and external hybrid implementation are acceptable for improved bandwidth. |
Compared with HMC572LC5, HMC1048LP5E trades integrated LO multiplication for broader low-end RF coverage, while QPB1022 offers extended high-frequency reach at the cost of added external components and no inherent image rejection - making HMC572LC5 optimal for compact, calibrated Ka-band receivers.

FAQ
What is the recommended LO drive level for optimal performance of the HMC572LC5?
The HMC572LC5 achieves best conversion gain (8 dB) and image rejection (18 dB) at +4 dBm LO drive. Performance degrades outside +2 to +8 dBm range: gain drops >1 dB below +2 dBm, and noise figure increases above +6 dBm. Always verify LO power at the HMC572LC5 pin using calibrated RF measurement, as insertion loss in routing affects delivered level.
Does the HMC572LC5 require external DC blocking on its IF outputs?
Yes - the HMC572LC5 IF1 and IF2 pins are DC-coupled but require external series capacitors for AC-coupled operation. For DC-coupled use, each IF pin must sink/source ≤3 mA; exceeding this risks non-function or permanent damage. Typical designs use 100 pF–1 nF capacitors sized for the target IF bandwidth (DC–3.5 GHz).
Can the HMC572LC5 operate across the full 24–28 GHz RF band with consistent image rejection?
Yes - datasheet plots confirm ≥14 dB image rejection across 23–28 GHz at +25 °C, with typical performance of 17–18 dB between 24.5–26.5 GHz. At temperature extremes (−40 °C/+85 °C), rejection dips to ≥14 dB minimum, meeting spec across full band and operating temperature range.
What is the thermal resistance and maximum power dissipation of the HMC572LC5?
The HMC572LC5 has a channel-to-package-bottom thermal resistance (RTH) of 104.6 °C/W. At TA = 85 °C, max continuous power dissipation is 860 mW; above 85 °C, it derates linearly at 9.56 mW/°C. With 3.5 V and 165 mA typical current, power dissipation is ~578 mW - well within safe limits with proper PCB copper area and thermal vias under the paddle.
Is the HMC572LC5 pin-compatible with any other Hittite/Analog Devices I/Q mixers?
No - the HMC572LC5 uses a unique 32-pin 5×5 mm layout optimized for its internal LNA/mixer/multiplier architecture. Pin functions (e.g., separate VddLO, VddLO2, VddRF) differ from alternatives like HMC1048LP5E (24-pin) or HMC8192 (32-pin but different pinout). Board redesign is required for substitution.
