Product details
Overview
HMC524LC3BTR-R5 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC I/Q mixer operating from 22–32 GHz RF/LO and DC–4.5 GHz IF, delivering 13 dB typical conversion loss, 20 dB image rejection, +20 dBm input IP3, and 40 dB LO-to-RF isolation in a 3×3 mm SMT package - used as an image-reject mixer or single-sideband upconverter in millimeter-wave radios.
For engineers reviewing the HMC524LC3BTR-R5 datasheet, HMC524LC3BTR-R5 pinout, HMC524LC3BTR-R5 application, or HMC524LC3BTR-R5 equivalent, key selection criteria include RF bandwidth coverage (22–32 GHz), IF DC-coupled capability, amplitude/phase balance tolerance (±0.5 dB / ±2.5°), thermal rating (−55°C to +85°C), and MSL3 reflow compatibility.
Technical Context
The HMC524LC3BTR-R5 integrates standard Hittite GaAs MESFET mixer cells with an on-die 90° hybrid to enable quadrature signal processing without external hybrids. It supports both downconversion (IRM mode) and upconversion with external IF hybrid, requiring only +17 dBm LO drive for optimal performance.
Its DC–4.5 GHz IF bandwidth accommodates baseband and wideband intermediate frequencies, while its 12-lead alumina package provides RF ground integrity via seven dedicated GND pins and an exposed paddle - critical for maintaining isolation and amplitude/phase balance across 22–32 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 22–32 GHz - covers E-band point-to-point and VSAT uplink/downlink bands |
| IF Frequency Range | DC–4.5 GHz - enables direct baseband I/Q sampling and wide IF channelization |
| Conversion Loss (IRM) | 10–13 dB typ - defines system noise figure impact when used as image-reject downconverter |
| Image Rejection | 18–20 dB typ - determines adjacent-channel interference suppression in receiver front-ends |
| Input IP3 | +20 dBm - sets third-order intermodulation dynamic range for multi-carrier signals |
| LO–RF Isolation | 35–40 dB - reduces LO leakage into antenna path, easing filter requirements |
| Amplitude Balance | ±0.5 dB - ensures I/Q signal symmetry for accurate complex modulation/demodulation |
| Phase Balance | ±2.5° - maintains quadrature fidelity critical for SSB upconversion sideband suppression |
Pinout & Package
Package: 12-lead 3×3 mm ceramic SMT (alumina body, gold-over-nickel plating, MSL3, exposed ground paddle). All ground leads (Pins 1,3,7,8,10,11,12) and paddle must be soldered to PCB RF ground per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7, 8, 10, 11, 12 | GND | RF/DC ground reference; mandatory connection to PCB ground plane for isolation and balance |
| 2 | RF | 50 Ω AC-coupled RF port; matched input for 22–32 GHz signal path |
| 4 | IF1 | DC-coupled I-channel IF output; supports DC–4.5 GHz with ≤3 mA current limit |
| 6 | IF2 | DC-coupled Q-channel IF output; identical electrical behavior to IF1 |
| 5 | N/C | No internal connection; may be grounded without performance impact |
| 9 | LO | 50 Ω DC-coupled LO input; requires +17 dBm drive for specified conversion and balance |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic I/Q architecture | Integrates 90° hybrid and dual mixer cells on single GaAs die - eliminates wirebonding and external hybrid assembly |
| DC-coupled IF outputs | Supports true baseband I/Q generation and zero-IF receivers without blocking capacitors |
| High LO–RF isolation | 40 dB typ minimizes LO radiation risk in full-duplex or TDD systems with shared antennas |

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4E | Wider RF range (17–32 GHz), higher conversion loss (14.5 dB), larger 4×4 mm QFN package | Better low-band coverage but lower integration density; requires more board area | Select when 17–22 GHz extension is needed and 3×3 mm footprint is not constrained |
| Qorvo QM11020 | 24–34 GHz RF range, +18 dBm IP3, 16 dB image rejection, 2.5×2.5 mm package | Higher frequency reach but reduced linearity and image rejection; smaller footprint | Select for compact 28 GHz 5G FR2 modules where size outweighs IP3/image trade-offs |
Compared with HMC524LC3BTR-R5, HMC1048LP4E extends low-end RF coverage at the cost of conversion loss and size, while QM11020 offers miniaturization below 3×3 mm but sacrifices 2 dB image rejection and 2 dB IP3 - making HMC524LC3BTR-R5 optimal for E-band systems prioritizing balance, rejection, and thermal reliability.

FAQ
What is the recommended LO drive level for optimal performance of the HMC524LC3BTR-R5?
The HMC524LC3BTR-R5 achieves best conversion loss, image rejection, and amplitude/phase balance at +17 dBm LO drive. Performance degrades outside +13 to +19 dBm range - below +13 dBm increases conversion loss; above +19 dBm risks compression and spurious generation. The datasheet specifies all key parameters at +17 dBm, and the device's absolute maximum LO rating is +27 dBm.
Can the HMC524LC3BTR-R5 be used for DC-coupled baseband I/Q interfaces?
Yes, the HMC524LC3BTR-R5 supports true DC-coupled IF operation on both IF1 and IF2 ports. Each port must be biased within ±3 mA to prevent die malfunction or failure. For non-DC applications, external series capacitors are required - but for zero-IF receivers or direct-conversion transceivers, DC coupling enables full baseband signal integrity without high-pass filtering artifacts.
What is the thermal resistance and maximum channel temperature of the HMC524LC3BTR-R5?
The HMC524LC3BTR-R5 has a junction-to-die-bottom thermal resistance (RTH) of 191.5 °C/W and a maximum channel temperature of 150°C. At 85°C ambient, its continuous power dissipation is 340 mW, derating linearly by 9.8 mW/°C above that. Proper grounding of all seven GND pins and the exposed paddle is essential to realize this thermal performance in PCB layouts.
Does the HMC524LC3BTR-R5 require external quadrature hybrid components?
No - the HMC524LC3BTR-R5 integrates the 90° hybrid on-die using GaAs MESFET technology, eliminating need for external hybrids in standard IRM or SSB upconverter configurations. External hybrids are only required for specialized upconversion setups where IF phase alignment must be tuned externally; the device's internal hybrid delivers ±2.5° phase balance across 22–32 GHz.
What are the ESD handling requirements for the HMC524LC3BTR-R5?
The HMC524LC3BTR-R5 is rated Class 1A per HBM (≥250 V), indicating high sensitivity to electrostatic discharge. Handling requires grounded wrist straps, conductive foam storage, and ionized air workstations. The LO, RF, and IF pins connect directly to GaAs MESFET gates - uncontrolled ESD can cause latent or catastrophic failure, especially during reflow or manual placement.
