Product details
Overview
HMC400MS8E from Analog Devices (formerly Hittite Microwave) is a high-dynamic-range passive GaAs MMIC mixer in an 8-lead MSOP package, operating from 1.7–2.2 GHz RF, 1.4–2.15 GHz LO, and DC–300 MHz IF. It delivers +36 dBm input IP3 (downconversion), 8.8 dB typical conversion loss, and +21 dBm input P1dB at +17 dBm LO drive-enabling robust signal mixing in GSM/UMTS base station receivers.
For engineers reviewing the HMC400MS8E datasheet, HMC400MS8E pinout, HMC400MS8E application, or HMC400MS8E equivalent, key selection criteria include its no-bias operation, ultra-small 14.8 mm² footprint, 50 Ω matched RF/LO ports, and suitability for low-side LO architectures in infrastructure transceivers requiring high linearity and wide IF bandwidth.
Technical Context
This single-ended passive FET mixer uses GaAs Schottky diode-based topology with no DC bias required. Its RF and LO ports are internally AC-coupled and 50 Ω matched across full band; the IF port is DC-coupled and supports operation to DC (≤ ±40 mA).
Performance is specified at TA = +25°C with +17 dBm LO drive and 200 MHz IF (downconversion mode). LO isolation exceeds 20 dB (RF-to-LO) and 16 dB (LO-to-IF); spurious outputs are suppressed ≥24 dBc for dominant mRF±nLO terms at 2 GHz RF / 1.8 GHz LO.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 1.7–2.2 GHz - fully specified performance across entire band for cellular infrastructure bands. |
| LO Drive Level | +16 to +18 dBm - fixed optimal drive range; no external tuning or level control needed. |
| Input IP3 (Downconv.) | +36 dBm typ. - enables reception of strong interferers without distortion in dense RF environments. |
| Conversion Loss | 8.8 dB typ. - defines signal attenuation from RF to IF; impacts system noise figure and gain budget. |
| LO–RF Isolation | 22–33 dB - reduces LO leakage into antenna path, easing front-end filter requirements. |
| IF Bandwidth | DC–300 MHz - supports direct-conversion and low-IF architectures up to UMTS/PCS channel bandwidths. |
| P1dB (Input) | +21 dBm typ. - sets maximum undistorted RF input level before compression degrades dynamic range. |
Pinout & Package
Package: 8-lead MSOP (Mini Small Outline Package), RoHS-compliant, matte Sn finish, MSL1, 14.8 mm² body area. Exposed paddle must be soldered to PCB RF ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | AC-coupled, 50 Ω matched input; requires external DC blocking if LO source has non-zero DC potential. |
| 2, 4 | N/C | No internal connection; must remain unconnected per design. |
| 3, 6, 7 | GND | RF ground terminals; all must be soldered directly to PCB ground plane with low-inductance paths. |
| 5 | IF Port | DC-coupled output; supports DC–300 MHz; current-limited to ±40 mA for safe operation. |
| 8 | RF Port | DC-coupled, 50 Ω matched input; accepts RF signals up to +27 dBm absolute max rating. |
Key Features
| Feature | Design Value |
|---|---|
| No external components or DC bias | Reduces BOM count and layout complexity; eliminates bias network design, filtering, and thermal drift concerns. |
| +36 dBm input IP3 (downconversion) | Outperforms many active mixers in linearity while avoiding associated noise and power consumption penalties. |
| Ultra-small MSOP footprint (14.8 mm²) | Enables high-density RF module integration where space is constrained, e.g., multi-channel RRUs and small-cell radios. |
| DC–300 MHz IF bandwidth | Supports both zero-IF and low-IF receiver architectures without external IF transformers or baluns. |
| High LO–RF isolation (up to 33 dB) | Minimizes LO radiation back through antenna path, reducing need for additional suppression filters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1040LP3E | Wider RF band (0.5–6 GHz), higher conversion loss (9.5 dB), +32 dBm IP3, 16-pin QFN package. | Better suited for multi-band lab equipment; larger footprint and higher loss reduce suitability for space-constrained infrastructure. | Select when broad frequency coverage outweighs size and linearity trade-offs. |
| ADL5801ACPZ-R7 | Active double-balanced mixer; 7–1200 MHz IF, +27 dBm IP3, +13 dBm P1dB, requires +5 V bias and external matching. | Offers better noise figure but lower linearity and higher power; needs bias circuitry and layout tuning. | Select only when IF bandwidth >300 MHz or integrated LO buffer is required; not drop-in compatible. |
Compared with HMC1040LP3E and ADL5801ACPZ-R7, the HMC400MS8E provides superior IP3 and smaller footprint for 1.7–2.2 GHz infrastructure use cases, while eliminating bias complexity-making it optimal for cost- and size-sensitive high-linearity downconverters.

FAQ
What is the recommended LO drive level for optimal performance of the HMC400MS8E?
The HMC400MS8E is characterized and optimized for +16 to +18 dBm LO drive, with +17 dBm used for all typical specifications including +36 dBm IP3 and 8.8 dB conversion loss. Operating outside this range degrades linearity and increases conversion loss; the device does not require external LO amplification or attenuation when driven within this window.
Can the HMC400MS8E be used in upconversion mode, and what are its key upconversion specs?
Yes, the HMC400MS8E supports upconversion with +29 dBm input IP3 and 8.8 dB conversion loss at +17 dBm LO drive. Its DC–300 MHz IF bandwidth and 1.7–2.2 GHz RF range make it suitable for translating baseband or low-IF signals to PCS/GSM bands; LO–IF isolation remains ≥16 dB, minimizing feedthrough in transmit paths.
Is DC coupling supported on all ports of the HMC400MS8E, and what are the limits?
The RF and IF ports are DC-coupled; the LO port is AC-coupled. The IF port must not sink or source more than ±40 mA DC current to avoid damage. The RF port tolerates +27 dBm RF input (absolute max), but DC voltage on RF or IF pins must be limited to prevent junction breakdown-external DC blocking is required only on LO if source has non-zero DC offset.
What is the thermal operating range and reliability classification of the HMC400MS8E?
The HMC400MS8E operates from –40°C to +85°C and is rated for storage from –65°C to +150°C. It carries MSL1 moisture sensitivity, allowing unlimited floor life before reflow. The RoHS-compliant matte Sn finish supports peak reflow up to 260°C, and the exposed paddle must be soldered to PCB ground for thermal and RF performance.
Does the HMC400MS8E require external matching components or baluns for 50 Ω system integration?
No. The HMC400MS8E integrates internal 50 Ω matching on RF and LO ports across 1.7–2.2 GHz and 1.4–2.15 GHz respectively; no external matching networks, baluns, or transformers are needed. The IF port is DC-coupled and 50 Ω compliant-only a series capacitor is required if DC blocking is desired above the IF bandwidth of interest.
