Product details
Overview
HMC520ALC4TR-R5 from Analog Devices is a GaAs MMIC in-phase/quadrature (I/Q) mixer designed for RF-to-IF downconversion and IF-to-RF upconversion in 6–10 GHz microwave systems. It delivers 8 dB typical conversion loss, 23 dBc image rejection, and supports dc–3.5 GHz IF bandwidth - enabling high-fidelity single-sideband signal processing in point-to-point radios and test instrumentation.
For engineers reviewing the HMC520ALC4TR-R5 datasheet, HMC520ALC4TR-R5 pinout, HMC520ALC4TR-R5 application, or HMC520ALC4TR-R5 equivalent, key selection criteria include its 6–10 GHz RF/LO range, integrated 90° hybrid architecture, surface-mount ceramic LCC package, and verified performance as both image-reject downconverter and single-sideband upconverter.
Technical Context
The HMC520ALC4TR-R5 implements two double-balanced mixer cells with an on-die 90° hybrid in a GaAs MESFET process, eliminating external hybrids for I/Q signal path generation. Its RF, LO, and dual IF ports are internally matched to 50 Ω, with ac-coupled RF and dc-coupled LO interfaces.
It operates across −40°C to +85°C with 15 dBm LO drive, delivering stable amplitude/phase balance (≤0.3 dB / ≤5°) and >20 dBm input IP3 over its full band - critical for suppressing image and sideband interference in wideband SSB architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 6 GHz to 10 GHz - defines usable input signal band for downconversion without external filtering or tuning. |
| LO Frequency Range | 6 GHz to 10 GHz - matches RF band, enabling high-side or low-side injection for flexible SSB translation. |
| IF Frequency Range | DC to 3.5 GHz - supports baseband and wideband IF outputs, including zero-IF and complex IF architectures. |
| Conversion Loss | 8 dB typical - quantifies signal attenuation through mixing; lower values preserve system noise figure and dynamic range. |
| Image Rejection | 23 dBc typical - measures suppression of unwanted image sideband; enables clean SSB operation without external image filters. |
| Input IP3 | 19 dBm typical - indicates linearity headroom; allows handling of strong interferers in dense RF environments. |
| LO–RF Isolation | 43 dB typical - limits LO leakage into antenna path, reducing spurious emissions and receiver desensitization. |
Pinout & Package
Package: 24-terminal RoHS-compliant ceramic leadless chip carrier (LCC), E-24-11 outline, with exposed thermal pad requiring GND connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 4 | RF | RF input port, ac-coupled and 50 Ω matched - connects directly to antenna or filter output without external matching. |
| 15 | LO | LO input port, dc-coupled and 50 Ω matched - accepts +15 dBm drive; no bias tee required. |
| 9, 11 | IF1, IF2 | Quadrature IF output (downconvert) or input (upconvert); dc-capable up to ±12 mA - supports zero-IF and complex IF designs. |
| 3, 5, 12, 14, 16, 19 | GND | Ground terminals - must be connected to low-inductance PCB ground plane; exposed pad also requires GND tie-down. |
| 1, 2, 6–8, 10, 13, 17–24 | NIC | Not internally connected - left floating; no routing or soldering required. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 90° hybrid | Enables true I/Q mixing on-die - eliminates discrete hybrid components and associated layout sensitivity and loss. |
| Surface-mount LCC package | 24-terminal ceramic leadless carrier with exposed thermal pad - supports automated reflow assembly and efficient heat dissipation. |
| DC–3.5 GHz IF bandwidth | Supports baseband and wideband IF signals - enables direct-conversion receivers and broadband upconverters without IF transformers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC774ALC3TR | Wider RF/LO range (6–14 GHz), higher conversion loss (9.5 dB typ), same 24-pin LCC package. | Better suited for Ka-band extensions; less optimal for 6–10 GHz where HMC520ALC4TR-R5 offers lower loss and better image rejection. | Select HMC774ALC3TR only when extending beyond 10 GHz; otherwise prefer HMC520ALC4TR-R5 for optimized 6–10 GHz performance. |
| ADL5375-05 | SiGe-based IQ modulator (not mixer), 0.3–6 GHz IF, requires external LO buffer, different 24-pin QFN package. | Designed for direct-conversion transmitter (modulator), not receiver/downconverter; incompatible pinout and biasing. | Use ADL5375-05 only in transmit-path IQ modulation; HMC520ALC4TR-R5 remains preferred for receive-path image-reject downconversion. |
Compared with HMC774ALC3TR and ADL5375-05, the HMC520ALC4TR-R5 provides superior image rejection (23 dBc vs. 18 dBc) and lower conversion loss (8 dB vs. 9.5 dB) specifically within 6–10 GHz - making it the optimal choice for high-performance microwave receiver front-ends requiring minimal external components.

FAQ
What is the recommended LO drive level for HMC520ALC4TR-R5?
The HMC520ALC4TR-R5 is characterized and optimized for +15 dBm LO input power across 6–10 GHz. Operating below this level increases conversion loss and degrades image rejection; exceeding +17 dBm risks compression and reduced linearity. The datasheet specifies absolute maximum LO power as +27 dBm, but +15 dBm delivers best balance of conversion loss, IP3, and image rejection for HMC520ALC4TR-R5.
Does HMC520ALC4TR-R5 require external matching networks?
No - the HMC520ALC4TR-R5 features internal 50 Ω matching on RF (ac-coupled) and LO (dc-coupled) ports, and its IF1/IF2 ports are dc-capable up to ±12 mA. External matching is unnecessary for standard 50 Ω system interfaces; only proper PCB layout (ground vias, controlled impedance traces) and GND connection of the exposed pad are required for HMC520ALC4TR-R5 to meet datasheet performance.
Can HMC520ALC4TR-R5 operate with DC-coupled IF outputs?
Yes - the IF1 and IF2 ports of HMC520ALC4TR-R5 support dc-coupled operation, enabling true zero-IF receiver architectures. However, current must remain within ±12 mA per port to avoid malfunction or damage. For ac-coupled use above ~100 kHz, off-chip dc-blocking capacitors may be added without affecting HMC520ALC4TR-R5 functionality.
What is the thermal resistance (θJC) of HMC520ALC4TR-R5?
The junction-to-case thermal resistance (θJC) of HMC520ALC4TR-R5 is 225°C/W, measured per JEDEC JESD51-2 with a 3×3 via array under the exposed pad. This value assumes the exposed pad is soldered to a solid GND plane; inadequate thermal land pattern or insufficient vias will degrade actual thermal performance and limit continuous power dissipation of HMC520ALC4TR-R5.
Is HMC520ALC4TR-R5 suitable for upconversion applications?
Yes - the HMC520ALC4TR-R5 functions as a single-sideband upconverter when IF signals are applied to IF1/IF2 and the desired RF output is extracted from the RF port. With 7.5 dB typical conversion loss and 22 dBc sideband rejection at 100 MHz IF, HMC520ALC4TR-R5 supports clean SSB synthesis in transmitters, confirmed in the "Upconverter Performance" section of its datasheet.
