Product details
Overview
HMC208AMS8 from Hittite Microwave Corporation (now part of Analog Devices) 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 at +13 dBm LO drive-ideal for compact wireless transceivers requiring high linearity and broadband mixing.
For engineers reviewing the HMC208AMS8 datasheet, HMC208AMS8 pinout, HMC208AMS8 application, or HMC208AMS8 equivalent, key selection criteria include its passive architecture, temperature-stable performance across –40°C to +85°C, ultra-small MSOP-8 footprint, and suitability for up/downconversion in space-constrained RF front-ends.
Technical Context
This passive GaAs Schottky diode-based mixer uses on-chip planar transformer baluns to achieve inherent double-balanced operation-rejecting even-order harmonics and suppressing LO leakage without external filtering. Its RF and LO ports are matched to 50 Ω, while the IF port supports DC-coupled operation.
The device functions as an upconverter, downconverter, biphase modulator, or phase comparator. Performance remains stable over temperature and LO drive level (+10 to +15 dBm), with P1dB input compression at +10 dBm (typ.) and >20 dB LO–RF isolation across its full 0.7–2.0 GHz band.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range (RF/LO) | 0.7–2.0 GHz - Enables coverage of cellular bands (e.g., GSM 850/900, DCS 1800, PCS 1900) and ISM 2.4 GHz in single device |
| IF Bandwidth | DC–0.5 GHz - Supports baseband I/Q demodulation and low-IF architectures without AC coupling constraints |
| Conversion Loss | 9 dB (typ.) at +13 dBm LO - Low loss preserves SNR in receiver chains and reduces required IF gain stages |
| Input IP3 | +17 dBm (typ.) at +13 dBm LO - High linearity mitigates intermodulation distortion in multi-carrier base station receivers |
| LO–RF Isolation | 24 dB (typ.) - Reduces LO radiation into antenna path, easing EMI compliance and simplifying front-end filtering |
| 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 per ESD-sensitive device protocols during assembly |
Pinout & Package
Package: MSOP-8 (Mini Small Outline Package), 3.0 × 3.0 mm body, 0.65 mm lead pitch, Sn/Pb lead finish, MSL1 rating. Ground leads (pins 1, 2, 7, 8) must be soldered directly to PCB RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 7, 8 | Ground | RF and DC return paths; all four pins require low-inductance connection to solid ground plane for optimal isolation and loss |
| 3 | RF Input | 50 Ω matched single-ended RF port; accepts 0.7–2.0 GHz signals for downconversion or upconversion |
| 4 | LO Input | 50 Ω matched single-ended LO port; requires +10 to +15 dBm drive for specified conversion loss and IP3 |
| 5 | IF Output | Differential IF output (internally center-tapped); DC-coupled, supports 0–500 MHz baseband or low-IF signals |
| 6 | IF Output (Complement) | Complementary IF terminal; used with Pin 5 to extract balanced IF signal or terminate for single-ended use |
Key Features
| Feature | Design Value |
|---|---|
| Passive GaAs MMIC Architecture | No bias required-eliminates DC power supply, quiescent current, and associated noise in sensitive receiver paths |
| On-Chip Planar Transformer Baluns | Enables intrinsic double-balancing without external hybrids or ferrites-reducing board area and component count |
| Ultra-Small MSOP-8 Footprint | 3.0 × 3.0 mm outline fits high-density RF modules including PCMCIA cards and miniaturized cable modems |
| Temperature-Stable Conversion Loss | Variation < ±0.5 dB from –40°C to +85°C at +13 dBm LO-ensures consistent link budget across environmental extremes |
| High LO–IF Isolation | 17 dB (typ.)-minimizes LO feedthrough into IF processing stages, reducing dynamic range compression in ADCs |
Applications
| Base Station Transceivers | PCMCIA Wireless Cards |
|---|---|
Use Scenario: LTE/FDD and TD-SCDMA macrocell and microcell transceivers requiring compact, high-linearity downconversion from 1.8–2.0 GHz RF to 70 MHz IF. IC Role / Device Role / Timing Role: Passive double-balanced downconverter providing RF-to-IF translation with minimal added noise and distortion. Use Value: +17 dBm IP3 and 9 dB conversion loss enable robust adjacent-channel rejection and improved receiver sensitivity without active gain compensation. |

IC Role / Device Role / Timing Role: Single-chip up/downconverter enabling full-duplex operation in half-duplex WLAN PHY layer. Use Value: MSOP-8 package and no-bias operation reduce PCB real estate and eliminate DC-DC converter requirements in battery-powered designs. |
| Cable Modem DOCSIS Front-End | Portable Test Equipment Receivers |

IC Role / Device Role / Timing Role: Broadband RF-to-IF mixer translating channelized spectrum to fixed 44 MHz IF for digitization. Use Value: DC–500 MHz IF bandwidth supports wide instantaneous bandwidth capture; 24 dB LO–RF isolation prevents LO leakage into upstream path. |
Use Scenario: Handheld spectrum analyzers and signal analyzers requiring low-profile, calibrated RF front-end mixing below 2 GHz. IC Role / Device Role / Timing Role: Precision downconverter in first IF stage, delivering repeatable conversion loss and spurious-free response. Use Value: Stable performance across temperature and LO drive enables factory calibration retention and field reliability without recalibration. |
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 typ.), same MSOP-8 package | Better suited for multi-band test equipment needing sub-1 GHz coverage; less optimal for narrowband 1.9 GHz cellular due to higher loss | Select when broader frequency coverage outweighs 1.5 dB conversion loss penalty and IF bandwidth remains sufficient |
| ADL5801ACPZ-R7 | Active mixer (requires 5 V bias), 0.4–6.0 GHz RF/LO, 8.2 dB conversion gain, +24 dBm IIP3 | Provides gain instead of loss-reduces need for IF amplification but adds power consumption and noise figure trade-off | Choose for receiver chains where system NF budget allows active device noise; avoid if zero-bias operation is mandatory |
Compared with HMC208AMS8, HMC1048LP3E extends frequency reach at the cost of conversion efficiency, while ADL5801ACPZ-R7 trades passive simplicity for gain and higher linearity-requiring DC bias and careful noise figure allocation.

FAQ
Does the HMC208AMS8 require DC bias voltage or current to operate?
No, the HMC208AMS8 is a fully passive GaAs MMIC double-balanced mixer and requires no DC bias. It operates solely with LO drive (typically +10 to +15 dBm) applied to Pin 4. This eliminates power supply design complexity, quiescent current draw, and associated thermal management in the HMC208AMS8 signal path.
What is the recommended LO drive level for optimal performance of the HMC208AMS8?
The HMC208AMS8 achieves best conversion loss (9 dB typ.), IP3 (+17 dBm), and isolation (24 dB LO–RF) at +13 dBm LO drive. Performance degrades below +10 dBm (higher loss, lower IP3) and shows diminishing returns above +15 dBm. The absolute maximum LO drive is +27 dBm-exceeding this risks permanent damage to the HMC208AMS8.
Can the HMC208AMS8 be used for both upconversion and downconversion?
Yes, the HMC208AMS8 is bidirectional and functions identically as an upconverter (IF→RF) or downconverter (RF→IF). Its symmetric RF/LO port design and broadband 0.7–2.0 GHz specification allow flexible use in either direction-verified in HMC208AMS8 application notes for GSM transmitters and WLAN receivers.
Is the HMC208AMS8 pin-compatible with the HMC208AMS8E variant?
Yes, the HMC208AMS8 and HMC208AMS8E share identical pinout, footprint, and electrical specifications. The only difference is lead finish (Sn/Pb vs. 100% matte Sn) and MSL reflow profile (235°C vs. 260°C peak), making them drop-in replacements in assembly-both labeled "H208A" on package marking.
What layout guidelines are critical for achieving specified HMC208AMS8 performance?
To meet HMC208AMS8 datasheet specs, all ground pins (1, 2, 7, 8) must connect directly to a solid RF ground plane via multiple low-inductance vias. RF, LO, and IF traces require controlled 50 Ω impedance; keep RF/LO paths short and isolated. Evaluation board 101828 (Rogers 4350 substrate) demonstrates proven layout practices for the HMC208AMS8.
