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 8 dB noise figure. It requires no external bias or components and is used in microwave radio transceivers where high LO–RF isolation (44 dB) and wideband operation are critical.
For engineers reviewing the HMC412AMS8G datasheet, HMC412AMS8G pinout, HMC412AMS8G application, or HMC412AMS8G equivalent, this page provides verified RF performance data, MSOP-8G package layout, temperature-stable SSB noise figure, LO drive range (+9 to +13 dBm), and real-world isolation metrics for downconverter design validation.
Technical Context
The HMC412AMS8G implements a passive diode-ring double-balanced architecture with 50 Ω matched RF and LO ports (AC-coupled RF, DC-coupled LO), and a DC-coupled IF port rated for ±4 mA. Its balanced topology suppresses even-order harmonics and provides inherent LO–RF and LO–IF isolation without external filtering.
It operates as a fundamental mixer with no internal active devices, supporting both upconverter and downconverter configurations. Performance is specified at TA = +25°C, IF = 1.45 GHz, and LO = +13 dBm, with stable conversion loss across –40°C to +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 9.0–15.0 GHz: Full-band operation without tuning or matching network changes |
| IF Bandwidth | DC–2.5 GHz: Supports baseband and low-IF architectures without DC blocking on IF |
| Conversion Loss | 8 dB typ: Predictable signal attenuation enabling accurate link budget planning |
| Input IP3 | 19 dBm typ: High linearity for multi-carrier microwave links with minimal intermodulation |
| LO–RF Isolation | 44 dB min: Reduces LO leakage into antenna path, easing filter requirements |
| Noise Figure (SSB) | 8 dB typ: Enables sensitive receiver front-end design in narrow-channel systems |
| LO Drive Range | +9 to +13 dBm: Compatible with standard GaAs and SiGe LO drivers without amplification |
Pinout & Package
Package: MSOP-8G (Mini Small Outline Package, exposed ground paddle), RoHS-compliant Sn/Pb lead finish, MSL1 rating, thermal resistance 230.5 °C/W (channel-to-ground).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | GND | RF ground terminals requiring low-inductance connection to PCB ground plane and exposed paddle |
| 2 | LO | DC-coupled 50 Ω input; accepts +9 to +13 dBm LO drive without external biasing |
| 3, 4, 6 | N/C | No internal connection; must be left unconnected or tied to ground per layout best practice |
| 5 | IF | DC-coupled output; supports DC–2.5 GHz but limited to ±4 mA current to prevent damage |
| 7 | RF | AC-coupled 50 Ω input; internal capacitor enables broadband RF interface without external DC block |
Key Features
| Feature | Design Value |
|---|---|
| No external bias or components required | Reduces BOM count and layout complexity; eliminates DC feed networks and decoupling capacitors |
| High LO–RF isolation (44 dB min) | Minimizes LO radiation in transmit paths and simplifies duplexer/filter design |
| DC–2.5 GHz IF bandwidth | Enables zero-IF and low-IF receiver topologies without IF AC coupling constraints |
| ±4 mA IF port current limit | Defines safe operating zone for DC-coupled IF interfacing with ADCs or baseband ICs |
| MSOP-8G SMT package with exposed paddle | Provides low thermal resistance (230.5 °C/W) and repeatable RF grounding via soldered paddle |
Applications
| Point-to-Point Microwave Radio | VSAT Outdoor Unit (ODU) |
|---|---|
Use Scenario: 11 GHz licensed band backhaul transceiver handling 256-QAM modulation with adjacent channel selectivity. IC Role / Device Role / Timing Role: Downconverter mixer translating 11.2–11.7 GHz RF to 70–520 MHz IF for demodulation. Use Value: 8 dB conversion loss and 44 dB LO–RF isolation maintain EVM < 3% under +13 dBm LO drive without external filtering. |
Use Scenario: Ku-band VSAT ODU receiving 12.25–12.75 GHz satellite signals in outdoor enclosures with –40°C to +65°C ambient. IC Role / Device Role / Timing Role: First-stage downconverter mixing satellite LNB output to 950–2150 MHz IF for cable distribution. Use Value: Stable 8 dB conversion loss and 8 dB noise figure across –40°C to +85°C enable consistent C/N ratio over full temperature range. |
| Long-Haul Terrestrial Radio | Millimeter-Wave Test Instrument Front-End |
Use Scenario: 13 GHz E-band hop with dual-polarized antennas requiring high dynamic range and low spurious generation. IC Role / Device Role / Timing Role: Balanced mixer in I/Q demodulator path for polarization diversity reception. Use Value: 19 dBm input IP3 and >30 dB RF–IF isolation suppress intermodulation from co-channel interferers in dense RF environments. |
Use Scenario: Signal analyzer front-end extending coverage to 15 GHz using harmonic mixing techniques. IC Role / Device Role / Timing Role: Fundamental-mode mixer providing calibrated IF output for spectrum analysis calibration traceability. Use Value: Documented spurious suppression (e.g., >85 dBc for 2LO–2RF) ensures measurement accuracy without post-processing correction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4E | Wider RF/LO range (6–20 GHz), higher conversion loss (9.5 dB typ), same MSOP-4 package footprint but different pinout | Supports Ka-band extensions but requires PCB redesign due to non-pin-compatible layout | Select when system requires >15 GHz operation and can accommodate revised layout |
| QPC1006 | Active GaAs mixer, 10–16 GHz range, 12 dB gain, +15 dBm P1dB, requires +5 V bias | Provides conversion gain instead of loss; suited for low-SNR receive chains needing amplification | Select when link budget demands gain over loss and bias supply is available |
Compared with HMC412AMS8G, HMC1048LP4E extends frequency coverage but increases conversion loss and mandates layout revision, while QPC1006 trades passive simplicity for active gain and added power management complexity-making HMC412AMS8G optimal for compact, bias-free, high-isolation microwave downconversion.

FAQ
What is the maximum LO drive level supported by the HMC412AMS8G?
The HMC412AMS8G supports a maximum LO drive level of +13 dBm, with optimal performance achieved between +9 dBm and +13 dBm. Exceeding +13 dBm risks degradation of conversion loss and increased distortion; absolute maximum rating is +24 dBm, but operation above +13 dBm is not characterized or recommended for reliable performance.
Can the HMC412AMS8G be used in an upconverter configuration?
Yes, the HMC412AMS8G supports upconversion with verified performance data shown in the datasheet. When used as an upconverter, the IF port serves as the input and the RF port as the output, maintaining 8 dB conversion loss and 19 dBm input IP3 across 9–15 GHz, provided LO drive remains within +9 to +13 dBm.
Is DC coupling required on the IF port of the HMC412AMS8G?
The IF port of the HMC412AMS8G is DC-coupled and supports operation from DC, but it must not source or sink more than ±4 mA to avoid die damage. For AC-coupled IF interfaces, a series capacitor sized for the target IF bandwidth may be added externally without affecting core mixer functionality.
What is the thermal resistance and maximum channel temperature for the HMC412AMS8G?
The HMC412AMS8G has a channel-to-ground thermal resistance of 230.5 °C/W and a maximum channel temperature rating of 150 °C. At 85 °C ambient, its continuous power dissipation is 280 mW, derating linearly by 4.3 mW/°C above that temperature to ensure safe operation within specification limits.
Does the HMC412AMS8G require external matching components?
No, the HMC412AMS8G requires no external matching components: RF, LO, and IF ports are internally matched to 50 Ω (RF and LO) or DC-coupled (IF), and its double-balanced architecture inherently suppresses even-order harmonics and LO leakage without external baluns or filters.
