Product details
Overview
HMC399MS8E from Analog Devices (formerly Hittite Microwave) is a high-dynamic-range passive GaAs MMIC mixer in an 8-lead MSOP package, operating from 700–1000 MHz RF, 540–900 MHz LO, and DC–250 MHz IF. 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 infrastructure transceivers without DC bias.
For engineers reviewing the HMC399MS8E datasheet, HMC399MS8E pinout, HMC399MS8E application, or HMC399MS8E equivalent, this device is selected for GSM/CDMA/W-CDMA base station receivers and cable modem termination systems where high linearity, small footprint (14.8 mm²), and single-inductor LO tuning are critical design requirements.
Technical Context
The HMC399MS8E is a single-ended passive FET mixer using GaAs Schottky diode architecture, optimized for low-side LO injection in downconversion mode. Its RF and LO ports are 50 Ω matched across band, while the IF port is DC-coupled with ±40 mA current limit.
LO drive sensitivity is narrowband-tuned via external 15–27 nH inductor (L1); no internal biasing or active circuitry is used. Performance is specified at TA = +25°C, LO = +17 dBm, and IF = 200 MHz, with guaranteed operation from –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 740–960 MHz - covers full GSM/EDGE (880–960 MHz) and CDMA (824–894 MHz) bands |
| LO Frequency Range | 540–900 MHz - supports low-side injection for 700–1000 MHz RF with ≥100 MHz IF spacing |
| IF Frequency Range | DC–250 MHz - enables direct baseband sampling and IF filtering down to DC |
| Input IP3 (Downconv.) | +35 dBm typical - suppresses third-order intermodulation in dense multi-carrier environments |
| Conversion Loss | 8.5 dB typical - defines signal attenuation from RF to IF; impacts receiver noise figure budget |

Pinout & Package
Package: 8-lead Mini Small Outline Package (MSOP), RoHS-compliant, matte tin finish, body material is low-stress injection-molded plastic. Dimensions per JEDEC MO-187 variant, with all ground pins (3,6,7) requiring direct connection to RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | AC-coupled 50 Ω input; requires series inductor (L1 = 15–27 nH) for frequency optimization |
| 2, 4 | N/C | No internal connection; must remain unconnected on PCB |
| 3, 6, 7 | GND | RF ground reference; all three must be soldered directly to solid ground plane with multiple vias |
| 5 | IF | DC-coupled output; supports DC–250 MHz; limited to ±40 mA current; DC-blocking cap required if DC not needed |
| 8 | RF | DC-coupled 50 Ω input; matched across 700–1000 MHz; accepts +25 dBm max RF input |
Key Features

FAQ
What is the absolute maximum LO input power for the HMC399MS8E?
The HMC399MS8E has an absolute maximum LO input power rating of +27 dBm. Exceeding this level risks permanent damage to the GaAs FET junctions. Operation at the recommended +16 to +18 dBm LO drive ensures optimal conversion loss, IP3, and LO isolation performance across temperature and process variation. Always verify LO source output impedance matches 50 Ω to avoid standing-wave voltage spikes.
Does the HMC399MS8E require external DC biasing?
No, the HMC399MS8E is a passive GaAs MMIC mixer and requires no DC biasing. It operates solely on RF and LO signal energy. The only external component needed is a series inductor (L1) on the LO pin for frequency response tuning. This eliminates bias networks, reduces heat generation, and improves system-level reliability in always-on infrastructure equipment.
Can the HMC399MS8E be used for upconversion applications?
Yes, the HMC399MS8E supports both downconversion and upconversion. Its +32 dBm input IP3 is specified for upconversion mode. When used as an upconverter, the IF port becomes the input and the RF port the output, with LO injected at the designated LO pin. Performance depends on proper impedance matching and LO drive level (+16 to +18 dBm remains optimal).
What is the recommended inductor value for LO tuning at 850 MHz RF?
For 850 MHz RF operation with low-side LO injection (e.g., LO ≈ 650 MHz), the recommended LO inductor (L1) value is 15 nH, per the application table on page 9-229. Use a high-Q, 0805-size RF inductor rated for ≥200 MHz self-resonant frequency. Tolerance should be ≤5% to maintain consistent LO match and minimize conversion loss variation across production units.
Is the HMC399MS8E still in active production?
The HMC399MS8E is marked "OBSOLETE" in the provided documentation, indicating it is no longer in active production by Analog Devices. However, Aetrix Electronics maintains legacy inventory and offers extended lifecycle support, including traceable sourcing and obsolescence mitigation planning for ongoing manufacturing programs reliant on this proven high-IP3 mixer.
