Product details
Overview
HMC208AMS8E from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer in MSOP-8 package, operating from 0.7–2.0 GHz RF/LO and DC–0.5 GHz IF. It delivers 9 dB typical conversion loss, +17 dBm input IP3, and 24 dB LO/RF isolation, enabling high-linearity downconversion in compact wireless transceivers.
For engineers reviewing the HMC208AMS8E datasheet, HMC208AMS8E pinout, HMC208AMS8E application, or HMC208AMS8E equivalent, key selection criteria include its ultra-small MSOP-8 footprint, temperature-stable performance from –40°C to +85°C, Class 1A ESD rating, and compatibility with +13 dBm LO drive for optimal noise figure and spurious suppression.
Technical Context
The HMC208AMS8E is a passive MMIC mixer built with GaAs Schottky diodes and integrated planar transformer baluns, eliminating external hybrid couplers. Its balanced architecture inherently suppresses even-order harmonics and LO leakage, supporting use as a downconverter, upconverter, biphase modulator, or phase comparator.
It operates over a wide LO/RF band (0.7–2.0 GHz) with fixed IF bandwidth up to 500 MHz and exhibits stable conversion loss (±1.5 dB), IP3 (+17 dBm typ.), and isolation (LO–RF ≥24 dB, LO–IF ≥17 dB) across temperature and LO drive levels from +10 to +13 dBm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range (RF/LO) | 0.7–2.0 GHz - Supports cellular, ISM, and broadband wireless bands without retuning. |
| IF Bandwidth | DC–0.5 GHz - Enables baseband and low-IF architectures with no high-pass filtering required. |
| Conversion Loss | 9 dB typ. @ LO = +13 dBm - Low signal attenuation preserves receiver sensitivity and simplifies gain staging. |
| Input IP3 | +17 dBm typ. @ LO = +13 dBm - High linearity prevents intermodulation distortion in dense RF environments. |
| LO–RF Isolation | 24 dB min. @ +13 dBm LO - Reduces LO radiation into antenna path, easing front-end filtering requirements. |
| Operating Temp. | –40°C to +85°C - Qualified for industrial and outdoor wireless infrastructure deployment. |
| ESD Rating | HBM Class 1A (≤250 V) - Requires strict handling but supports robust PCB-level ESD protection design. |
Pinout & Package
Package: RoHS-compliant MSOP-8 (3.0 × 3.0 × 1.1 mm), matte tin-plated copper alloy leadframe, MSL1 rated (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | Single-ended RF port; requires 50 Ω matching network and DC blocking capacitor. |
| 2 | LO Input | Single-ended LO port; accepts +10 to +13 dBm drive; must be AC-coupled and matched. |
| 3 | IF Output | Differential IF output; internal center-tap grounded-external balun or transformer needed for single-ended IF. |
| 4 | GND | RF ground connection; must be soldered directly to PCB ground plane with multiple vias. |
| 5 | GND | RF ground connection; same as Pin 4-dual grounding improves high-frequency return path integrity. |
| 6 | GND | RF ground connection; third dedicated ground pin enhances thermal and RF stability. |
| 7 | GND | RF ground connection; fourth ground pin ensures low-inductance return for all internal baluns. |
| 8 | NC | No connect; internally unconnected-must remain floating per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Passive GaAs MMIC architecture | No bias required-simplifies power design and eliminates quiescent current, thermal drift, and startup delay. |
| Integrated planar transformer baluns | Enables on-chip RF/LO/IF balance without external hybrids-reduces board area and insertion loss. |
| Ultra-small MSOP-8 footprint | 3.0 × 3.0 mm body enables dense RF module integration in PCMCIA cards and portable wireless devices. |
| High LO–IF isolation (≥17 dB) | Minimizes LO feedthrough into IF chain, reducing need for additional IF filtering and improving dynamic range. |
| Spurious output suppression | Typical nLO + mRF spurs ≤ –38 dBc at 1.1 GHz LO-meets spectral mask requirements for cable modem and base station IF stages. |

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 (0.3–4.0 GHz), higher conversion loss (10.5 dB), larger 3×3 mm QFN package. | Better suited for multi-band SDR and test equipment requiring extended frequency coverage. | Select when broader bandwidth outweighs size and loss constraints; not pin-compatible with HMC208AMS8E. |
| LT5560IDDB#TRPBF | SiGe active mixer, +5 V supply required, 12.5 dB conversion gain, lower IP3 (+12 dBm), DC–3 GHz IF. | Preferred where gain is critical and DC power is available; unsuitable for passive, zero-bias designs. | Choose only if system can accommodate active biasing and trade IP3 for gain; different topology and pinout. |
Compared with HMC208AMS8E, HMC1048LP3E offers wider frequency coverage but sacrifices size and efficiency, while LT5560IDDB#TRPBF provides conversion gain at the cost of linearity and bias complexity-neither is pin-compatible, and each requires distinct layout and filtering strategies.

FAQ
What is the recommended LO drive level for optimal performance of the HMC208AMS8E?
The HMC208AMS8E achieves best conversion loss (9 dB), noise figure (9 dB), and IP3 (+17 dBm) at +13 dBm LO drive. Performance degrades below +10 dBm (loss increases ~1.5 dB, IP3 drops ~4 dBm). Drive above +13 dBm yields diminishing returns and risks accelerated aging. The HMC208AMS8E datasheet specifies +13 dBm as the nominal LO condition for all key specs.
Does the HMC208AMS8E require DC bias or external power?
No, the HMC208AMS8E is a fully passive GaAs MMIC mixer with no DC bias pins or supply requirements. It operates solely on RF and LO signal energy. All four ground pins (Pins 4–7) must be soldered to the PCB ground plane, but no voltage or current is applied to the device. This eliminates quiescent power draw and thermal management concerns in the HMC208AMS8E design.
Can the HMC208AMS8E be used for both upconversion and downconversion?
Yes, the HMC208AMS8E is bidirectional and functions identically as an upconverter or downconverter due to its symmetric double-balanced topology. When RF and LO ports are swapped, it translates IF to RF (upconversion); when used conventionally, it translates RF to IF (downconversion). The HMC208AMS8E's datasheet explicitly lists both roles, and its isolation specs apply regardless of directionality.
What is the meaning of "MSOP-8" and how does it differ from standard SOIC-8 for the HMC208AMS8E?
MSOP-8 (Mini Small Outline Package) measures 3.0 × 3.0 mm with 0.65 mm lead pitch-40% smaller than SOIC-8 (4.9 × 6.0 mm). The HMC208AMS8E uses MSOP-8 to minimize parasitic inductance and enable high-frequency RF routing. Its leadframe is copper alloy with matte Sn plating (RoHS), and all ground leads must be soldered to ensure RF return integrity-unlike SOIC-8, which lacks optimized RF grounding provisions.
Is the HMC208AMS8E still in active production, and what is its obsolescence status?
The HMC208AMS8E is marked OBSOLETE by Analog Devices per official documentation, but Aetrix Electronics maintains active inventory and offers lifecycle support including last-time buy planning and cross-reference guidance. While no new wafer starts are scheduled, existing stock is traceable and qualified for continued use in legacy designs and repair programs through Aetrix Electronics' managed supply chain.
