Product details
Overview
HMC399MS8TR from Analog Devices (formerly Hittite Microwave) is a high-dynamic-range passive GaAs MMIC mixer in MSOP-8 package, operating RF 700–1000 MHz, LO 540–900 MHz, and IF DC–250 MHz. It delivers +35 dBm input IP3 (downconversion), 8.5 dB typical conversion loss, 23–35 dB LO isolation, and +23 dBm input P1dB - enabling robust signal mixing in cellular base station receivers.
For engineers reviewing the HMC399MS8TR datasheet, HMC399MS8TR pinout, HMC399MS8TR application, or HMC399MS8TR equivalent, this device supports high-linearity downconversion in GSM/CDMA/W-CDMA infrastructure where low external part count, no DC bias, and ultra-small 14.8 mm² footprint are critical design constraints.
Technical Context
This monolithic passive FET mixer uses GaAs Schottky diode architecture with single-ended RF and LO ports and DC-coupled IF output. Its performance relies on external LO matching via a series inductor (L1) and optional IF AC coupling, with all ground pins (3, 6, 7) requiring direct connection to RF ground plane.
It operates without DC bias, distinguishing it from active mixers, and achieves high linearity through optimized GaAs process and impedance-matched RF port (50 Ω, 700–1000 MHz). LO drive range is tightly specified at +16 to +18 dBm for optimal IP3 and conversion loss across temperature (−40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 700–1000 MHz - fully specified band for 50 Ω matched RF input; enables direct integration into 850/900 MHz cellular front-ends. |
| Input IP3 (Downconv.) | +35 dBm @ TA = +25°C, LO = +17 dBm - supports high-signal environments like BTS receivers without compression or intermodulation distortion. |
| Conversion Loss | 8.5 dB typical - defines signal attenuation from RF to IF; lower than many passive mixers, reducing post-mixer gain requirements. |
| LO–RF Isolation | 23–35 dB - suppresses LO leakage into antenna path, easing filtering requirements in TDD/FDD architectures. |
| IF Bandwidth | DC–250 MHz - supports baseband and low-IF receiver designs including zero-IF and 200 MHz IF plans used in EDGE/GPRS. |
| P1dB (Input) | +23 dBm - sets maximum undistorted RF input level; aligns with high-power cellular transmit leakage scenarios. |
| Package | MSOP-8 (14.8 mm²) - industry-standard surface-mount footprint with thermal and RF grounding optimized for PCB layout. |
Pinout & Package
Package: MSOP-8, plastic body, RoHS-compliant (HMC399MS8TR corresponds to RoHS version per marking "H399" and MSL1 rating; max reflow 260°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | AC-coupled 50 Ω input; requires external series inductor (e.g., 15–27 nH) for LO frequency optimization per application table. |
| 2, 4 | N/C | No internal connection; must remain unconnected and unstubbed to avoid parasitic resonance. |
| 3, 6, 7 | GND | RF ground terminals; all three must be soldered directly to solid PCB ground plane with multiple vias for low-inductance return path. |
| 5 | IF | DC-coupled output; sinks/sources ≤ ±40 mA; use series capacitor if DC blocking required for IF frequencies >0 Hz. |
| 8 | RF | DC-coupled 50 Ω input, matched across 700–1000 MHz; no external matching needed for nominal operation. |
Key Features
| Feature | Design Value |
|---|---|
| No DC bias required | Eliminates bias network complexity, reduces BOM count, and removes quiescent power consumption - critical for low-power remote radio units. |
| +35 dBm input IP3 | Enables coexistence with strong adjacent-channel interferers in dense spectrum deployments such as urban macrocells. |
| Single external inductor (L1) | Minimizes external component count to one RF inductor for LO tuning - simplifies layout and improves repeatability vs. multi-component matching networks. |
| Ultra-small MSOP-8 footprint (14.8 mm²) | Reduces PCB area by >50% vs. SOIC-8 or QFN alternatives - ideal for space-constrained small-cell and distributed antenna systems. |
| LO drive tolerance (+16 to +18 dBm) | Allows flexibility in LO amplifier selection and accommodates gain variation across temperature and process corners without retuning. |
Applications
| GSM/EDGE Base Station Receiver | W-CDMA Femtocell Downconverter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive high-IP3 mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4E | Wider RF range (1.7–2.7 GHz), higher conversion loss (9.5 dB), same MSOP-8 package. | Targets LTE/TD-LTE bands; not suitable for sub-1 GHz GSM/CDMA without external matching. | Select when operating above 1.7 GHz; verify LO drive compatibility (+13 to +17 dBm). |
| LT5560IMS8E#PBF | Lower IP3 (+24 dBm), wider IF (DC–400 MHz), requires DC bias (5 V), different pinout (8-lead MSOP but non-compatible). | Used in general-purpose IF sampling and instrumentation; lacks GSM-optimized linearity. | Choose only for cost-sensitive, lower-dynamic-range applications where DC bias is acceptable. |
Compared with HMC399MS8TR, HMC1048LP4E extends frequency coverage but sacrifices sub-1 GHz optimization and linearity, while LT5560IMS8E trades linearity and bias-free operation for broader IF bandwidth and higher integration - making HMC399MS8TR uniquely suited for high-reliability 700–1000 MHz infrastructure mixing.

FAQ
What is the recommended LO drive level for optimal performance of the HMC399MS8TR?
The HMC399MS8TR achieves best-in-class IP3 and conversion loss at LO drive levels between +16 dBm and +18 dBm. Operating outside this range increases conversion loss or degrades linearity; +17 dBm is the reference condition for all key specs including +35 dBm IP3 and 8.5 dB conversion loss. The device does not require precise LO amplitude control, allowing tolerance for amplifier gain drift across temperature.
Does the HMC399MS8TR require DC bias voltage or current to operate?
No, the HMC399MS8TR is a passive GaAs FET mixer and requires no DC bias. It operates solely on RF and LO signal energy. This eliminates bias network components, reduces power consumption, and avoids potential failure modes associated with bias circuitry - a key advantage over active mixers in high-reliability infrastructure applications.
Can the HMC399MS8TR be used for upconversion, and what is its upconversion IP3?
Yes, the HMC399MS8TR supports upconversion with verified +32 dBm input IP3 under standard test conditions (LO = +17 dBm, RF = 950 MHz, IF = 100 MHz). Its symmetrical passive architecture allows bidirectional operation, though LO–RF isolation (19–25 dB) is lower than LO–IF isolation, requiring careful filtering in transmit paths.
What is the maximum allowable IF current for the HMC399MS8TR's IF pin (Pin 5)?
The IF pin (Pin 5) of the HMC399MS8TR must not sink or source more than ±40 mA of DC current. Exceeding this limit risks permanent damage. For DC-coupled IF interfaces, ensure downstream circuitry (e.g., op-amp input or ADC driver) presents appropriate DC load; for AC-coupled operation, use a series capacitor sized per desired IF low-frequency cutoff.
Is the HMC399MS8TR pin-compatible with the obsolete HMC399MS8 or HMC399MS8E variants?
Yes, the HMC399MS8TR shares identical MSOP-8 pinout, footprint, and electrical interface with both HMC399MS8 (Sn/Pb) and HMC399MS8E (100% matte Sn). All three variants use the same pin functions, absolute maximum ratings, and application circuit - enabling drop-in replacement in existing designs without PCB changes.
