Product details
Overview
HMC175MS8 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer in MSOP-8 package, operating from 1.7–4.5 GHz RF/LO and DC–1.0 GHz IF. It delivers 8 dB typical conversion loss, +18 dBm input IP3, 30 dB LO/RF isolation, and supports up/downconversion in compact SMT designs.
For engineers reviewing the HMC175MS8 datasheet, HMC175MS8 pinout, HMC175MS8 application, or HMC175MS8 equivalent, key selection criteria include broadband RF/LO frequency coverage, low conversion loss at +13 dBm LO drive, high LO-to-RF/IF isolation, thermal stability across –40°C to +85°C, and compatibility with 50 Ω RF layout practices on Rogers 4350 substrates.
Technical Context
The HMC175MS8 is a passive, diode-based double-balanced mixer architecture using GaAs Schottky barrier diodes integrated into a monolithic MMIC. It requires no DC bias and operates solely on LO injection, enabling true zero-bias operation with minimal power overhead.
Its balanced topology suppresses even-order harmonics and LO leakage, delivering 32 dB LO/IF isolation and >30 dB LO/RF isolation across its full 1.7–4.5 GHz band - critical for dense-signal environments like mini-base stations and portable wireless transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 1.7–4.5 GHz: Full operational bandwidth for PCS, ISM, and LTE bands without external tuning. |
| IF Frequency Range | DC–1.0 GHz: Supports baseband and low-IF architectures including I/Q demodulation. |
| Conversion Loss | 8 dB typ.: Predictable signal attenuation enables accurate link budget planning with margin. |
| Input IP3 | +18 dBm typ.: High linearity reduces intermodulation distortion in multi-carrier systems. |
| LO/RF Isolation | 30 dB typ.: Minimizes LO feedthrough into antenna paths, easing filter requirements. |
| Operating Temp | –40°C to +85°C: Validated performance across industrial temperature range without derating. |
| ESD Rating | HBM Class 1A: Requires strict ESD handling but supports standard PCB assembly with care. |
Pinout & Package
Package: MSOP-8 (0.118″ × 0.190″ × 0.040″), RoHS-compliant variant HMC175MS8E uses 100% matte Sn lead finish; non-RoHS HMC175MS8 uses Sn/Pb. All ground leads must be soldered directly to PCB RF ground plane per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 6, 7, 8 | Ground | RF and DC return paths; must connect to solid ground plane via multiple vias. |
| 4 | RF Input | Differential RF port requiring 50 Ω matched trace; sensitive to layout asymmetry. |
| 5 | LO Input | Single-ended LO port; accepts +13 dBm drive; not DC-coupled. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small MSOP-8 footprint | 0.118″ × 0.190″ area saves board space in portable and PCMCIA form factors. |
| No DC bias required | Zero-power quiescent state simplifies power domain design and eliminates bias network noise. |
| High LO-to-IF isolation | 32 dB typ. reduces IF-stage desensitization and eases post-mixer filtering. |
| Thermal stability | P1dB and IP3 vary <±1 dB over –40°C to +85°C, enabling stable RF performance without calibration. |
Applications
| Mini-Base Stations | Portable Wireless Terminals |
|---|---|
Use Scenario: Compact macrocell and microcell transceivers requiring low-profile, high-isolation mixing in 1.8–2.6 GHz PCS/UMTS bands. IC Role / Device Role / Timing Role: Downconverter for receive path and upconverter for transmit path, replacing discrete balun+diode solutions. Use Value: 30 dB LO/RF isolation reduces front-end filter complexity; 8 dB conversion loss maintains receiver sensitivity. | Use Scenario: Handheld radios, military comms, and battery-powered test equipment needing low-power, small-footprint RF mixing. IC Role / Device Role / Timing Role: Passive mixer core in direct-conversion or low-IF architectures with zero-bias operation. Use Value: No DC bias eliminates standby current; MSOP-8 size fits tight PCB real estate constraints. |
| PCMCIA Wireless Cards | ISM Band Transceivers (2.4/5.8 GHz) |
Use Scenario: Legacy laptop expansion cards requiring SMT-compatible RF front-end integration within strict mechanical envelope. IC Role / Device Role / Timing Role: Dual-role mixer supporting both TX modulation and RX demodulation in half-duplex mode. Use Value: Single-device solution replaces discrete mixers and baluns, reducing BOM count and assembly cost. | Use Scenario: Industrial IoT gateways and Wi-Fi coexistence test fixtures operating in 2.4 GHz ISM band. IC Role / Device Role / Timing Role: Frequency translator between baseband processor and 50 Ω antenna interface. Use Value: +18 dBm IP3 handles adjacent-channel interference; DC–1 GHz IF supports flexible digital IF processing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC174MS8 | Narrower 1.7–2.7 GHz RF/LO range; 9 dB conversion loss; same MSOP-8 package. | Optimized for PCS band only; less suitable for 3.5 GHz TDD-LTE or 4.5 GHz point-to-point links. | Select when operating strictly below 2.7 GHz and higher conversion loss is acceptable. |
| ADL5801ACPZ-R7 | Active mixer with 5.5 dB conversion gain; requires +5 V bias; 0.5–2.5 GHz RF range; LFCSP-24 package. | Enables gain instead of loss but adds power, heat, and layout complexity; incompatible pinout and biasing. | Choose only if system requires conversion gain and can accommodate active bias and larger footprint. |
Compared with HMC175MS8, HMC174MS8 trades bandwidth for marginal LO drive efficiency, while ADL5801ACPZ-R7 shifts from passive simplicity to active complexity - making HMC175MS8 optimal for wideband, zero-bias, space-constrained SMT designs.

FAQ
What is the recommended LO drive level for optimal performance of the HMC175MS8?
The HMC175MS8 is characterized at +13 dBm LO drive, delivering 8 dB typical conversion loss, +18 dBm input IP3, and 30 dB LO/RF isolation. Lower LO drive increases conversion loss and degrades IP3; exceeding +13 dBm yields diminishing returns and risks compression. Absolute maximum LO is +27 dBm, but sustained operation above +15 dBm is not recommended for reliability.
Does the HMC175MS8 require DC bias or external baluns?
No, the HMC175MS8 is a passive double-balanced mixer with no DC bias requirement. It integrates on-chip baluns and operates with single-ended LO and differential RF ports. External baluns are unnecessary - RF and LO traces must be impedance-matched to 50 Ω, and all ground pins must connect directly to the PCB ground plane.
What is the thermal performance of the HMC175MS8 across its operating temperature range?
The HMC175MS8 maintains stable RF performance from –40°C to +85°C. Conversion loss varies ≤0.5 dB, P1dB shifts <1 dB, and IP3 changes <1.5 dB across this range under +13 dBm LO drive. No thermal compensation or recalibration is needed for most applications, supporting unattended industrial deployment.
Can the HMC175MS8 be used as a biphase modulator or demodulator?
Yes, the HMC175MS8's double-balanced architecture supports biphase (I/Q) modulation and demodulation. When driven with quadrature LO signals on its RF port and baseband data on its IF port, it functions as a modulator; reversed, it acts as a demodulator. This capability is documented in Hittite application notes and validated in evaluation board testing (e.g., Eval Board 101650).
Is the HMC175MS8 still in active production, and what is its obsolescence status?
The HMC175MS8 is marked "OBSOLETE" in official documentation, but functional units remain available through authorized distributors and Aetrix Electronics' legacy inventory. It is supported for life-of-program continuity in existing designs; no second-source replacement has been officially designated by Analog Devices.
