Product details
Overview
HMC399MS8ETR 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, and +23 dBm input P1dB for GSM/CDMA/W-CDMA infrastructure receivers and transmitters.
For engineers reviewing the HMC399MS8ETR datasheet, HMC399MS8ETR pinout, HMC399MS8ETR application, or HMC399MS8ETR equivalent, this device supports low-external-part-count RF front-ends requiring high linearity, wide IF bandwidth, and no DC bias in compact 14.8 mm² footprint.
Technical Context
The HMC399MS8ETR is a single-ended passive FET mixer with monolithic GaAs construction. Its architecture relies on balanced switching without active biasing, enabling zero quiescent current and inherent robustness against LO drive variation (+16 to +18 dBm typical).
LO injection is AC-coupled via external series inductor L1 (15–27 nH), while RF and IF ports are DC-coupled and 50 Ω matched across band. LO-to-RF isolation ranges 23–35 dB and LO-to-IF isolation reaches 29–35 dB, supporting clean signal translation in dense spectral environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 700–1000 MHz - fully specified operation for cellular bands including GSM850, DCS1800, and PCS1900 |
| LO Frequency Range | 540–900 MHz - supports low-side injection downconversion and upconversion with optimized L1 tuning |
| IF Frequency Range | DC–250 MHz - enables baseband and low-IF architectures without external DC blocking at IF port |
| Input IP3 (Downconv.) | +35 dBm @ +17 dBm LO - enables reception of strong interferers without distortion in BTS receivers |
| Conversion Loss | 8.5 dB typical - defines minimum gain budget required in cascaded receiver chain before IF amplification |
| LO to RF Isolation | 23–35 dB - reduces LO leakage into antenna path, easing filter requirements in TDD/FDD systems |
| P1dB (Input) | +23 dBm - allows direct connection to power amplifier output stages or high-level signal sources |
Pinout & Package
Package: RoHS-compliant MSOP-8 (14.8 mm²), 100% matte Sn lead finish, MSL1 rated, max reflow 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | AC-coupled 50 Ω input; requires external series inductor (L1 = 15–27 nH) for impedance matching across LO band |
| 2, 4 | N/C | No internal connection; must remain unconnected per datasheet to avoid parasitic coupling |
| 3, 6, 7 | GND | RF ground terminals; all must be soldered directly to PCB ground plane with low-inductance vias |
| 5 | IF | DC-coupled output; supports DC–250 MHz; limited to ±40 mA DC current to prevent damage |
| 8 | RF | DC-coupled 50 Ω input; matched across full 700–1000 MHz RF band without external components |
Key Features
| Feature | Design Value |
|---|---|
| No DC bias required | Zero quiescent current simplifies power design and eliminates thermal drift from bias networks |
| +35 dBm input IP3 | Enables coexistence with strong adjacent-channel signals in multi-carrier base stations |
| Ultra-small MSOP-8 footprint | 14.8 mm² area reduces PCB real estate vs. SOIC or QFN alternatives in space-constrained modules |
| Single external inductor (L1) | Minimizes BOM count and layout complexity while maintaining LO frequency flexibility |
| DC-coupled IF port | Supports true baseband I/Q demodulation and eliminates need for DC-blocking capacitors in IF path |
Applications
| GSM/EDGE Base Station Receiver | W-CDMA Femtocell Transmitter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF range (1.7–2.7 GHz), higher conversion loss (9.5 dB), same MSOP-8 package | Targets LTE/5G FR1 bands instead of sub-1 GHz legacy cellular | Select when operating above 1 GHz; verify LO drive compatibility (+13 to +17 dBm) |
| LT5560IMS8E#PBF | Active mixer, +22 dBm IP3, +12 dB conversion gain, requires +5 V bias and consumes 20 mA | Suitable for low-IF or zero-IF receivers where gain and lower LO drive are prioritized over linearity | Choose only if DC power and thermal management are available; not drop-in compatible |
Compared with HMC399MS8ETR, HMC1048LP3E extends frequency coverage but sacrifices linearity and efficiency, while LT5560IMS8E trades passive simplicity for active gain and higher power consumption-neither is pin-compatible, and both require layout and bias redesign.

FAQ
What is the recommended LO drive level for optimal performance of the HMC399MS8ETR?
The HMC399MS8ETR achieves best IP3 and conversion loss at +16 to +18 dBm LO drive, with +17 dBm specified as typical test condition. Deviating below +16 dBm degrades IP3; exceeding +18 dBm risks reliability due to absolute maximum LO rating of +27 dBm. The HMC399MS8ETR does not require precise LO level control but benefits from stable, clean LO sources.
Can the HMC399MS8ETR be used for upconversion, and what is its upconversion IP3?
Yes, the HMC399MS8ETR supports upconversion with +32 dBm input IP3 at +17 dBm LO drive, as confirmed in the datasheet's electrical specifications table and upconverter characterization plots. Its symmetric passive topology enables bidirectional use, though LO-to-RF isolation (19–25 dB) must be considered in transmit chain filtering.
Is an external inductor required for the LO port of the HMC399MS8ETR, and why?
Yes, an external series inductor (L1 = 15–27 nH, depending on LO frequency) is mandatory on Pin 1 (LO) to form a resonant matching network with internal capacitance. Without L1, LO return loss exceeds –5 dB and conversion performance degrades significantly. The HMC399MS8ETR's "low external part count" claim assumes inclusion of this single critical component.
Does the HMC399MS8ETR support DC-coupled IF operation, and what are the current limits?
Yes, Pin 5 (IF) is DC-coupled and supports operation from DC to 250 MHz. However, the HMC399MS8ETR specifies a strict ±40 mA absolute maximum DC current limit at the IF port. Exceeding this may cause permanent damage; external current-limiting or AC-coupling is required if IF-stage DC bias exceeds this threshold.
What is the thermal operating range and storage limit for the HMC399MS8ETR?
The HMC399MS8ETR is rated for continuous operation from –40 °C to +85 °C ambient, with storage temperature spanning –65 °C to +150 °C. These limits apply to the RoHS-compliant MSOP-8 package (HMC399MS8E variant); the Pb-free matte Sn finish supports lead-free reflow up to 260 °C peak, consistent with J-STD-020 MSL1 classification.
