Product details
Overview
HMC787AG-SX from Analog Devices is a GaAs MMIC fundamental double-balanced mixer operating from 3 GHz to 10 GHz RF, with dc–4 GHz IF bandwidth and 17 dBm LO drive requirement. It delivers 9 dB typical conversion loss, 24 dBm input IP3, and 43 dB typical LO-to-IF isolation, enabling high-linearity downconversion and upconversion in microwave transceivers.
For engineers reviewing the HMC787AG-SX datasheet, HMC787AG-SX pinout, HMC787AG-SX application, or HMC787AG-SX equivalent, this page provides verified RF mixer specifications, ceramic LCC package interface details, thermal and isolation performance across temperature, and validated alternatives for microwave radio and test equipment design.
Technical Context
The HMC787AG-SX implements a passive double-balanced topology using GaAs MESFET process, requiring no external matching components or bias circuitry. Its optimized balun structures deliver >43 dB LO-to-IF isolation and >26 dB RF-to-IF isolation across the full 3–10 GHz band.
It operates as both upconverter and downconverter with fixed 17 dBm LO drive level, supports dc-coupled IF output (≤±12 mA), and maintains stable conversion loss and IP3 over −40°C to +85°C ambient temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF range (2–18 GHz), higher conversion loss (10.5 dB), lower IP3 (21 dBm), same 12-pin LCC package | Better suited for Ka-band extensions; less optimal for 3–6 GHz where HMC787AG-SX offers superior IP3 | Select HMC1048LP3E only when >10 GHz coverage is mandatory; otherwise prefer HMC787AG-SX for lower distortion in C/X-band |
| HMC558LC3B | Narrower RF range (4–8 GHz), lower conversion loss (8.5 dB), higher IP3 (26 dBm), identical E-12-4 package and pinout | Optimized for 5G FR1 and satellite comms; not rated below 4 GHz or above 8 GHz | HMC558LC3B is a direct functional alternative within 4–8 GHz; use HMC787AG-SX for full 3–10 GHz coverage |
Compared with HMC1048LP3E and HMC558LC3B, the HMC787AG-SX uniquely balances 3–10 GHz bandwidth, 9 dB conversion loss, and 24 dBm IP3 in a standard LCC package-making it the preferred choice for broadband microwave radios requiring consistent linearity across C- and X-bands without trade-offs in frequency coverage.

FAQ
What is the operating temperature range for the HMC787AG-SX?
The HMC787AG-SX is specified for continuous operation from −40°C to +85°C ambient temperature. Performance parameters-including conversion loss, IP3, and isolation-are characterized across this range, with data shown in Figures 7–9 and 30–31 of the Rev. C datasheet. Thermal resistance (θJA = 120°C/W) assumes proper PCB grounding via the exposed pad.
Does the HMC787AG-SX require external biasing or matching components?
No. The HMC787AG-SX is a passive double-balanced mixer fabricated in GaAs MESFET technology and requires no external biasing, DC blocking, or impedance-matching networks. All ports (LO, RF, IF) are internally matched to 50 Ω except the dc-coupled IF port, which must be current-limited to ±12 mA for dc operation.
Can the HMC787AG-SX be used for zero-IF (direct-conversion) receiver designs?
Yes. The HMC787AG-SX supports dc-coupled IF output with a bandwidth extending from dc to 4 GHz, making it suitable for zero-IF architectures. However, the IF port must not source or sink more than ±12 mA to avoid device malfunction or failure, as specified in the Absolute Maximum Ratings table.
What is the recommended LO drive level for the HMC787AG-SX?
The HMC787AG-SX is designed for a nominal LO drive level of 17 dBm, as confirmed in all specification tables and performance plots. Deviating significantly from this level degrades conversion loss and IP3-e.g., Figure 10 shows conversion gain variation of >2 dB between 13 dBm and 21 dBm LO power at 25°C.
How does the exposed pad on the HMC787AG-SX package function electrically and thermally?
The exposed pad on the HMC787AG-SX is an integral part of the RF/dc ground reference and must be soldered directly to the PCB ground plane using ≥9 thermal vias. It serves dual roles: maintaining balun symmetry for high isolation and dissipating up to 1044 mW of power (at TA = 85°C), with θJC = 86°C/W to the pad.
