Product details
Overview
HMC412AMS8G from Analog Devices (formerly Hittite Microwave) is a passive double-balanced mixer operating from 9.0 to 15.0 GHz RF/LO, with DC–2.5 GHz IF bandwidth, 8 dB typical conversion loss, 19 dBm input IP3, and no external bias or components required. It serves as a core downconverter in microwave radio transceivers requiring high LO-to-RF isolation (44 dB) and stable performance across –55°C to +85°C.
For engineers reviewing the HMC412AMS8G datasheet, HMC412AMS8G pinout, HMC412AMS8G application, or HMC412AMS8G equivalent, this page delivers verified RF mixer specifications, MSOP8G package layout, real-world isolation and linearity data, and direct alternatives for 9–15 GHz wireless infrastructure designs.
Technical Context
The HMC412AMS8G implements a passive diode-ring double-balanced architecture with 50 Ω matched RF and LO ports (AC- and DC-coupled respectively) and a DC-coupled IF port supporting operation to baseband. Its balanced topology inherently suppresses even-order harmonics and provides high port-to-port isolation without external baluns.
It operates with +9 to +13 dBm LO drive, delivering flat 8 dB conversion loss across full band and maintaining 8 dB noise figure (SSB) at IF = 1.45 GHz. No DC biasing is needed, and thermal resistance is specified at 230.5 °C/W (channel-to-ground paddle).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 9.0–15.0 GHz - Enables use in X- and Ku-band satellite uplinks and point-to-point microwave radios. |
| IF Bandwidth | DC–2.5 GHz - Supports baseband I/Q demodulation and wideband IF sampling without external DC blocking on IF. |
| Conversion Loss | 8 dB typ. - Predictable signal attenuation simplifies link budget planning without active gain stages. |
| Input IP3 | 19 dBm - Ensures robust two-tone linearity in dense spectral environments like VSAT hubs. |
| LO–RF Isolation | 44 dB - Minimizes LO leakage into antenna paths, reducing spurious emissions and easing filter requirements. |
| Operating Temp. | –55°C to +85°C - Qualified for outdoor microwave radio enclosures and unheated remote sites. |
| ESD Rating | HBM Class 1A - Requires strict handling per ESD-sensitive device protocols during assembly. |
Pinout & Package
Package: MSOP-8G (exposed ground paddle), RoHS-compliant variant HMC412AMS8GE uses matte Sn finish; standard HMC412AMS8G uses Sn/Pb. MSL1 rating; max reflow 235°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | GND | RF ground terminals - must be soldered to top-layer ground plane and connected via multiple vias to internal ground. |
| 2 | LO | DC-coupled 50 Ω LO input - accepts +9 to +13 dBm drive without external matching or blocking. |
| 3, 4, 6 | N/C | No internal connection - left floating; no PCB trace routing required. |
| 5 | IF | DC-coupled IF output - supports DC–2.5 GHz; limited to ±4 mA DC current to prevent die damage. |
| 7 | RF | AC-coupled 50 Ω RF input - requires external DC blocking capacitor if DC feed is present upstream. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4E | Wider RF/LO range (6–18 GHz), higher conversion loss (9.5 dB typ.), same MSOP-4 package footprint but different pinout. | Supports C- and X-band overlap; less suitable for narrow 9–15 GHz optimization due to broader bandwidth trade-offs. | Select when multi-band coverage outweighs conversion loss penalty and board redesign accommodates pinout change. |
| QPC1006 | Higher frequency (12–18 GHz), lower IP3 (16 dBm), GaAs pHEMT-based active mixer requiring +5 V bias and external matching. | Requires active bias network and stability compensation; not drop-in due to power, decoupling, and layout dependencies. | Choose only when gain is mandatory and system can accommodate active mixer complexity and noise figure degradation. |
Compared with HMC412AMS8G, HMC1048LP4E offers broader band coverage at higher loss and incompatible pinout, while QPC1006 introduces active bias dependency and reduced linearity-neither is pin-compatible, and both require layout or schematic revision for substitution.

FAQ
What is the recommended LO drive level for optimal performance of the HMC412AMS8G?
The HMC412AMS8G achieves its specified 8 dB conversion loss and 19 dBm input IP3 with +13 dBm LO drive. Operation between +9 dBm and +13 dBm is supported; below +9 dBm increases conversion loss and degrades IP3. The HMC412AMS8G datasheet confirms +13 dBm as the reference condition for all key specs including isolation and noise figure.
Can the HMC412AMS8G be used in an upconverter configuration?
Yes, the HMC412AMS8G supports upconversion per its functional diagram and measured upconverter performance curves. When used as an upconverter, the IF port becomes the input and the RF port the output; LO drive remains +9 to +13 dBm. Conversion gain and isolation values shift slightly versus downconversion mode, as documented in the HMC412AMS8G application plots.
Is DC coupling supported on all ports of the HMC412AMS8G?
No. Only the LO and IF ports are DC-coupled; the RF port is AC-coupled and requires an external series capacitor if DC feed is present upstream. The HMC412AMS8G pin descriptions explicitly state RF is AC-coupled and matched to 50 Ω, while LO and IF are DC-coupled - violating this risks impedance mismatch and degraded return loss.
What is the maximum allowable DC current on the IF port of the HMC412AMS8G?
The HMC412AMS8G IF port must not source or sink more than ±4 mA DC current. Exceeding this limit risks non-function or permanent die failure, as stated in the Absolute Maximum Ratings table. This constraint applies regardless of IF frequency or signal level - it is a hard electrical limit defined in the HMC412AMS8G datasheet.
Does the HMC412AMS8G require external matching components or baluns?
No. The HMC412AMS8G is fully matched to 50 Ω on RF and LO ports and requires no external baluns, bias tees, or matching networks. Its double-balanced diode-ring architecture and internal matching enable direct 50 Ω interfacing - a key design feature confirmed in the HMC412AMS8G general description and "No External Components" feature bullet.
