Product details
Overview
EV1HMC521ALC4 from Analog Devices is a GaAs MMIC I/Q mixer designed for microwave downconversion and single-sideband upconversion in 8.5 GHz to 13.5 GHz RF systems. It delivers 9 dB typical conversion loss, 27.5 dBc image rejection, and supports dc–3.5 GHz IF bandwidth. Used in VSAT radios and military EW receivers where quadrature signal integrity and wide IF range are critical.
For engineers reviewing the EV1HMC521ALC4 datasheet, EV1HMC521ALC4 pinout, EV1HMC521ALC4 application, or EV1HMC521ALC4 equivalent, this page provides verified RF port definitions, thermal and isolation specs at 25°C/−40°C/+85°C, sideband suppression performance across LO power levels (11–19 dBm), and validated alternatives for image-reject receiver front-ends.
Technical Context
The EV1HMC521ALC4 integrates two double-balanced mixer cells with an on-die 90° hybrid coupler in a monolithic GaAs MESFET process. It operates as an image-reject downconverter or single-sideband upconverter without external hybrids, eliminating wire bonding and enabling surface-mount assembly.
Its RF and LO ports are ac-coupled and 50 Ω matched; IF1 and IF2 are dc-coupled quadrature outputs with ±2 mA absolute current limit. Performance is specified with 15 dBm LO drive and validated over −40°C to +85°C ambient temperature.

Pinout & Package
EV1HMC521ALC4 uses a 3.9 mm × 3.9 mm, 24-terminal ceramic LCC package (E-24-11) with exposed thermal pad requiring connection to ground. Ground pins (3, 5, 12, 14, 16) must be soldered to RF/dc ground planes per Figure 3 of the datasheet. Pins labeled NIC are not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 4 | RF Port | Ac-coupled 50 Ω RF input; connects to antenna or LNA output in downconverters. |
| 15 | LO Port | Ac-coupled 50 Ω local oscillator input; requires stable 15 dBm drive for optimal image rejection. |
| 11 | IF1 Port | DC-coupled in-phase IF output; must sink/source ≤2 mA for dc-coupled operation. |
| 9 | IF2 Port | DC-coupled quadrature-phase IF output; used with IF1 to reconstruct complex baseband signals. |
| 3, 5, 12, 14, 16 | GND | RF and DC ground terminals; all must be low-inductance connections to PCB ground plane. |
| EPAD | Exposed Pad | Thermal and electrical ground path; must be soldered to solid ground plane for θJC = 148°C/W. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC520LC4 | Same GaAs MMIC process but 6–14 GHz RF range; 10 dB conversion loss; 25 dBc image rejection. | Better low-end coverage (6 GHz), slightly lower image rejection; requires recalibration below 8.5 GHz. | Select for wider low-frequency coverage where 8.5 GHz lower edge is not mandatory. |
| Qorvo QM11036 | GaAs pHEMT-based; 7–14 GHz RF range; 8.5 dB conversion loss; 26 dBc image rejection; 4×4 mm QFN. | Smaller footprint but no exposed thermal pad; dc–3 GHz IF bandwidth vs. dc–3.5 GHz. | Choose for space-constrained layouts where 500 MHz IF bandwidth margin is acceptable. |
Compared with EV1HMC521ALC4, HMC520LC4 extends low-frequency operation at the cost of image rejection, while QM11036 offers compact packaging but reduced IF bandwidth and thermal performance-both require layout and matching network adjustments.

FAQ
What is the recommended LO drive level for optimal image rejection in EV1HMC521ALC4?
The EV1HMC521ALC4 achieves best image rejection (27.5 dBc typical) at 15 dBm LO input power. Lower drive (e.g., 11 dBm) degrades image rejection by ~3–5 dB; higher drive (19 dBm) increases conversion loss variation and risks compression. Maintain ±0.5 dB LO power stability for consistent quadrature balance in EV1HMC521ALC4.
Can EV1HMC521ALC4 operate with dc-coupled IF outputs, and what are the current limits?
Yes, EV1HMC521ALC4 supports dc-coupled IF operation on IF1 (Pin 11) and IF2 (Pin 9). Each IF pin must not source or sink more than ±2 mA; exceeding this risks die malfunction. For ac-coupled use above ~100 kHz, add external series capacitors sized per required IF bandwidth-no internal dc blocking is present in EV1HMC521ALC4.
How does temperature affect conversion loss and image rejection in EV1HMC521ALC4?
Over −40°C to +85°C, EV1HMC521ALC4 conversion loss varies by ≤0.5 dB, and image rejection degrades by ≤3 dBc (e.g., 27.5 dBc → 24.5 dBc at −40°C). These shifts are monotonic and repeatable; system calibration at extremes is recommended for precision applications using EV1HMC521ALC4.
Is the exposed pad of EV1HMC521ALC4 electrically connected, and how must it be handled?
Yes, the exposed pad of EV1HMC521ALC4 is electrically connected to ground and thermally critical. It must be soldered to a solid, low-impedance PCB ground plane using ≥80% solder coverage. Failure to connect it degrades θJA by >30°C/W and risks thermal runaway-this requirement is explicitly stated in the EV1HMC521ALC4 datasheet Pin Configuration section.
Does EV1HMC521ALC4 require external 90° hybrids for image-reject operation?
No, EV1HMC521ALC4 integrates a monolithic 90° hybrid coupler and two double-balanced mixer cells. It performs image-reject downconversion natively without external hybrids-this eliminates insertion loss, size, and alignment sensitivity associated with discrete hybrid assemblies in EV1HMC521ALC4-based designs.
