Product details
Overview
HMC219AMS8ETR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer in MSOP-8 package, operating from 4.5–9.0 GHz RF/LO with DC–2.5 GHz IF bandwidth, 8.5 dB typical conversion loss, and +13 dBm LO drive requirement. It serves as upconverter, downconverter, or phase comparator in microwave radios and UNII/HiperLAN systems.
For engineers reviewing the HMC219AMS8ETR datasheet, HMC219AMS8ETR pinout, HMC219AMS8ETR application, or HMC219AMS8ETR equivalent, key selection criteria include its 25 dB LO/RF isolation, +21 dBm input IP3, -40°C to +85°C operating range, and MSOP-8 footprint compatibility with RF layout best practices for 50 Ω impedance matching and ground via density.
Technical Context
This passive MMIC mixer uses integrated GaAs Schottky diodes and planar transformer baluns to achieve broadband double-balanced operation without external bias. Its architecture inherently suppresses even-order harmonics and LO feedthrough at RF and IF ports.
Performance is specified at TA = +25°C with LO = +13 dBm and IF = 100 MHz; conversion loss, noise figure, and isolation vary predictably across temperature (–40°C to +85°C) and LO drive level (+11 to +15 dBm), enabling stable system-level link budget planning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range (RF/LO) | 4.5–9.0 GHz - supports full UNII-3 (5.725–5.85 GHz) and HiperLAN/2 (5.15–5.35 GHz) bands plus extended microwave radio links up to 9 GHz. |
| IF Bandwidth | DC–2.5 GHz - enables baseband I/Q demodulation and wideband IF sampling without external lowpass filtering. |
| Conversion Loss | 8.5 dB typ. - defines minimum required LO power and sets cascaded noise figure floor in receiver chains. |
| LO–RF Isolation | 25 dB typ. - reduces LO radiation into antenna path, easing front-end filter requirements in transceivers. |
| Input IP3 | +21 dBm typ. - determines two-tone intermodulation headroom in dense-spectrum environments like multi-channel radios. |
| P1dB (Input) | +10 dBm typ. - defines maximum usable signal level before compression degrades EVM or BER in modulation schemes. |
| ESD Rating | Class 1A (HBM) - mandates strict handling protocols during PCB assembly to prevent gate oxide damage. |
Pinout & Package
Package: MSOP-8 (Mini Small Outline Package), RoHS-compliant, matte tin lead finish, MSL1 rating, 2.0 mm × 3.0 mm body, 0.65 mm pitch. Ground leads (pins 1, 2, 7, 8) must be soldered directly to PCB RF ground plane with multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 7, 8 | Ground | RF and DC return paths; all four must connect to solid ground plane with ≥4 thermal vias per pad to maintain 50 Ω impedance integrity. |
| 3 | RF Input | Differential RF port; requires 50 Ω microstrip feed with symmetric layout to preserve balance and minimize common-mode conversion. |
| 4 | IF Output | Single-ended IF output; DC-coupled, matched to 50 Ω; sensitive to parasitic capacitance-keep trace short and unshielded only if grounded properly. |
| 5 | LO Input | Differential LO port; driven with balanced +13 dBm signal; imbalance >0.1 dB degrades LO–RF isolation below 20 dB. |
| 6 | IF Output (Complement) | Complementary IF output; used with external balun or differential ADC to improve SNR by 3 dB over single-ended mode. |
Key Features
| Feature | Design Value |
|---|---|
| Double-balanced MMIC topology | Eliminates need for external baluns; achieves >25 dB LO–RF and LO–IF isolation without discrete transformers or ferrites. |
| GaAs Schottky diode integration | Enables operation up to 9 GHz with stable conversion loss variation <±0.5 dB across temperature and frequency. |
| Ultra-small MSOP-8 footprint | Reduces board area by >60% vs. SOIC-8 mixers; compatible with high-density RF modules and compact SDR platforms. |
| DC–2.5 GHz IF bandwidth | Supports direct-conversion architectures and zero-IF receivers without IF filtering bottlenecks. |
| Class 1A ESD protection | Validated per JEDEC JS-001; allows safe handling in Class 1000 cleanrooms without ionizers or wrist straps beyond standard protocol. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF/LO range (2–18 GHz), higher conversion loss (9.5 dB), larger QFN-16 package. | Better suited for multi-band test equipment; less optimal for space-constrained 5–6 GHz access points. | Select when broader frequency coverage outweighs board area and loss penalties. |
| ADL5801ACPZ-R7 | Active mixer with 5.5 dB NF, +27 dBm IIP3, requires +5 V bias; 24-lead LFCSP package. | Enables lower-noise receiver designs but adds power supply complexity and DC power draw. | Select when system-level noise figure dominates over LO drive simplicity and passive reliability. |
Compared with HMC219AMS8ETR, HMC1048LP3E trades size and efficiency for bandwidth scalability, while ADL5801ACPZ-R7 replaces passive simplicity with active gain and noise improvement at the cost of bias infrastructure and thermal management.

FAQ
What is the recommended LO drive level for optimal performance of the HMC219AMS8ETR?
The HMC219AMS8ETR achieves best conversion loss (8.5 dB) and IP3 (+21 dBm) at LO = +13 dBm. Performance degrades below +11 dBm (conversion loss rises to 10 dB) and above +15 dBm (increased distortion). The device tolerates up to +27 dBm LO without damage, but +13 dBm is the design target for repeatability and linearity. Always verify LO amplitude at the HMC219AMS8ETR pin using calibrated RF probe.
Does the HMC219AMS8ETR require DC bias or external baluns?
No, the HMC219AMS8ETR is a passive double-balanced mixer and requires no DC bias voltage or current. Its integrated GaAs Schottky diodes and on-chip planar transformer baluns eliminate the need for external baluns or bias tees. All pins are RF-coupled except ground leads (1, 2, 7, 8), which must connect directly to PCB ground. This simplifies layout and improves reliability versus active or unbalanced alternatives.
What is the maximum operating temperature and thermal derating guidance for the HMC219AMS8ETR?
The HMC219AMS8ETR is rated for continuous operation from –40°C to +85°C ambient. Conversion loss increases by ≤0.3 dB and IP3 decreases by ≤1.5 dB between –40°C and +85°C at +13 dBm LO. No thermal derating of LO or RF power is required within this range, but ensure PCB copper area and via count under the MSOP-8 body meet IPC-2221B Class B guidelines to avoid localized hot spots exceeding junction limits.
How does the HMC219AMS8ETR handle spurious outputs, particularly near harmonics of LO?
At LO = 6.1 GHz and RF = 6.0 GHz, the HMC219AMS8ETR produces mLO ± nRF spurs ≥62 dBc below IF power (e.g., 2LO–1RF at 6.2 GHz is –62 dBc). LO harmonics at the RF port are suppressed ≥30 dBc (e.g., 2×LO at 12.2 GHz is –32 dBc). These values are measured per datasheet Table 10-4 and remain stable across temperature, making the HMC219AMS8ETR suitable for spectral-clean applications like radar and licensed microwave links.
Is the HMC219AMS8ETR pin-compatible with the non-RoHS HMC219AMS8 variant?
Yes, the HMC219AMS8ETR and HMC219AMS8 share identical MSOP-8 pinout, mechanical dimensions, and electrical specifications. The sole difference is lead finish: HMC219AMS8ETR uses 100% matte Sn (RoHS), while HMC219AMS8 uses Sn/Pb. Both have MSL1 rating and same reflow profile (260°C peak for HMC219AMS8ETR, 235°C for HMC219AMS8), allowing drop-in replacement in new designs and backward compatibility in legacy rework.
